My fur baby was panting in pain and couldn't walk and we were unable to figure out why. Naturally, it was a Saturday night and his regular vet was closed. Took him into Animal Emergency Clinic in O'Fallon and they were quick to help me get my 70lb boy on a stretcher and off to be examined by the vet. They were busy and had several very acute cases. They professionally juggled sick and injured pets while comforting emotional parents. I was there several hours, but that is to be expected. The wait was actually very comfortable, there were vending machines for drinks and food as well as clean restroom facilities. The vet kept me regularly updated. My boy needed blood work and imaging, all available there. He was sent home with the medication he needed and a solid plan of care until he could be seen by his regular vet. The services were reasonably priced considering it's emergency care. I feel like they were fiscally cautious when choosing the diagnostics for my pet. If you feel you could wait until business hours you'll obviously spend less at your regular vet, but unfortunately accidents and unexpected illnesses happen and I'm grateful we have great emergency care close to home. The vet we saw was outstanding in his recommendations and I have confidence in the care received. Turns out my old man has a bad back, thankfully he's doing well. We will definitely use this Emergency Clinic again if needed. read more

Animal Emergency Clinic - Thanks for the great care! - Veterinarians Near Me - O'fallon, Missouri

We called on Sunday, May 17, 2026 because one of our dogs was having uncontrolled diarrhea for multiple days They offered zero support zero help we were willing to pay for an emergency visit and the gal who answered the phone was rude disrespectful and downplayed our dog issue. She basically said not to come in . So went went to another clinic who were extremely helpful. Beware !! read more

The LAST place you want to find yourself after hours is an emergency vet. However when my furry buddy had an issue I really couldn't wait. The staff was amazing, they cared for him (and me!) and he was patched up and ready to go home. I am so thankful they let my grumpy-Gus of a cat feel safe and cared for- he even looks dapper in the cone of shame! The price was reasonable and they were all so kind, you can tell they love animals. read more

No stars actually. They sent me away because the only vet present was leaving even though my dog was bleeding.

Went there on an emergency situation as my cat starting to collapse in the morning due to weakness while awaiting our appointment which won't be until the following week. They are very supportive. They took my cat in right away and when they found out they couldn't do much about it they were very honest about the situation and did not run unnecessary tests to waste my money but referred us right away to another place that could possibly help. Even offered a towel for my cat to stay warm and comfortable in his kennel as I totally did think about it because I was freaking out and beyond worried. Definitely recommend them read more

Nothing. I wouldn't bring my dog here again. How can you call yourself "Animal Emergency" when you don't even have a single doctor on staff when someone brings their dog in? read more

I took my cat there because I thought he had a UTI. After examining him, the vet met with me to discuss her findings and my options. Exam showed no obvious signs, so I was advised I could just take him home with some medication that would soothe his tummy, or have bloodwork or other tests done to rule out other issues. I elected to have the bloodwork done, just in case, which also came up negative. I did not feel pressure to have anything done, appreciate the straightforward way it was presented, and was happy that I went ahead with the bloodwork, knowing that it ruled other things out. All the staff were very pleasant, and the icing on the cake was when I received a text message this morning from the clinic asking how he was doing. Very nice - I highly recommend this clinic! read more

Animal Emergency Clinic 334 Fort Zumwalt Square, O'Fallon, MO 63366 This past Saturday we had to rush out 3-year-old English Bulldog to an Emergency Vet because she was turning purple and was unable to breath. The vet immediately came out and took her back and told us we had to wait, and she would be back to see us shortly. The first time the vet came out she had asked me if we would want her revived if she coded and I told her absolutely. My daughter and I were distraught because this had never happened before. They put her into an oxygen "tank", ice packed her down and gave her a sedative hoping to slow her breathing. They allowed us to come back and see her, and she was still struggling to breathe. We discussed options and the vet worked up an estimate for us. I immediately agreed that whatever was needed over the next 24 hours we were onboard with. We were then able to go back and see her again and she was starting to look much better. Her face and gums were looking pinker. We could tell that every time we came back and that we were keeping her from resting because when she saw or heard us, she would have her little tail wag and then try to get up. I paid the requested amount of 75% of the estimate before leaving and they assured me they would call me if anything changed during the evening. When the vets shift had ended, she called and gave me a run down on what was going on with our Gretta and that she was resting comfortably and was able to get off the oxygen she had been on. I called during the night to check on her and then at 6am I got a call saying that all the other tests they did came back negative of any concerns. When we got there to pick her up, they had filled a prescription for her to take when she gets anxious. They went over the care they had provided and answered any questions we had and then before leaving they had refunded us a third of what we had paid because the extra services that were in the estimate did not all have to take place. I certainly hope I never have to use an emergency vet ever again but if we do, I will not hesitate to go back to this facility. Thank you for the wonderful care you provided. read more

I called to get some advice on what to do for my elderly dog as she had a bone and was throwing up everywhere. They said I should come in just to be safe so it is exactly what I did. They examined my pet and she was given a few injections as well as some fluids and medication to take home. The medication was a slurry which was an added bonus as she hates pills. I am so thankful they were open and could help me with my animal emergency. It was also a fast process-- could've taken forever. Again I appreciate them so much! read more

worst place never EVER taking my puppy here again they are a scam they make u call a number and that number just tells u to go to the hospital and that's a $90 dollar phone call then just to walk into the doors is $170 the lady at the front desk with the bangs is sitting on her phone and eating snacks and honestly had a attitude. then it's the cost of what they need at the end so i just spent $600 dollars for no reason bc the $100 test they took to know if she was ok or not they still didnt even know the vet talked so slow it was like she had to rehearse it in the back. in quote "we still um like don't know if like she did eat it but like we still um have to treat it for the worst case" read more

Animal Emergency Clinic 334 Fort Zumwalt Square, O'Fallon, MO 63366 We wanted to share our experience with our fur-baby Tank Schwartz-Tieman. This was the WORST, MOST traumatic, brutal and upsetting way we had to say goodbye to our VERY loved fur-family member. We understand the main goal is to always save an animals life. We brought our Tank in with what we were told was bloat, which if that was an accurate diagnosis he had been suffering with it for 24 hours. Tank was an 11 year old lab-great dane mix, he had OBVIOUS muscle wasting (as even the staff noticed before we got him out of the truck), he had lumps all over (which our vet had already ran tests on and they were not cancer) and obviously was not in the best of health. We met with the Vet - who told us it was probably bloat and she proceeded right into a surgery pitch. We felt immediate pressure to do the surgery. We were quiet and so she said we should do X-Rays and bloodwork to see if there is anything else going on. We did agree to that without hesitation. She then started talking about surgery plans telling us there "MIGHT" be complications - Um ... Yes he is an 11 year old giant breed unhealthy pup! We did not agree in the end to the surgery and as she got up to walk out the door she turned around and said "No guilt if you dont do the surgery" it was VERY much an afterthought. They then brought him back to us and we made the hardest decision. The vet brought in the supplies, my husband and I were on the floor with Tank. I noticed that about 1/2 way thru his leg started to swell and balloon up from the injections. When the Dr noticed that I was seeing it, she stopped and said they would need to put another line in. Tank was laying there, high on morphine and 1/2 of the euthanasia drugs. He began freaking out not knowing what was happening. In our minds we were having to hold him down while they tried unsuccessfully to place another line in another leg, on the other leg they finally got it in. Now Tank is still freaking out, but getting sleepy and confused, there is blood all over the floor, along with shaved hair, and then he was gone. It was NOT peaceful, it was AWFUL, the WORST experience that noone should EVER have to go thru. We left there without our best friend and with our final memory being disturbing. We felt guilt, shame and despair. On TOP of the cost of the X-Rays & bloodwork we were NEVER even told the results, so now we are questioning if they were even done, OR was it even bloat? We WERE impressed with 1 of the techs, she offered us care, compassion and helped us manage our guilt. She also offered to help transfer his ashes if we found a Hippo Urn. We have had 2 past experiences here that were positive and peaceful, HOWEVER after this we will NEVER be back. There are just NO EXCUSES for the series of events that occured. read more

As Devastating as losing our Fur Baby was, this place made our crushing decision today to choose peace for our Beautiful 13 year old Golden Retriever a much better journey than we ever expected. They had so much compassion and respect for our family and our Girl. We would Highly recommend, in every aspect of this heartbreaking experience. read more

This is the LAST emergency clinic that you want to take your pet to. All they want to do is schedule tests, x rays, etc. only to tell you that the "test" was inconclusive and then charge you an exorbitant amount of money for nothing. All this clinic is for is to make money. Find somewhere else to go. read more

Animal Emergency Clinic - Sylvester - Veterinarians Near Me - O'fallon, Missouri

Horrible experience at this place, I took my dog at this clinic because he couldn't walk on his right leg but he could limp off his left leg, they told us he would get better soon and gave him an injection to relax his muscles but made him completely paralyzed and couldn't walk, his feet were flipped over and he couldn't move them back and couldn't feel them. They told us he was paralyzed and needed to get surgery. The surgery was extremely expensive for a dog and me and my family tried to see what other options we had, The staff and doctors were completely unprofessional they clearly didn't know what they were doing they didn't even offer getting a X-ray and didnt even explain what was going on with him. These doctors and staff clearly don't know how there actions can affect us. I don't know how people would even trust the staff with their pets. There is no coincidence that there are other cases exactly like my dogs. This clinic was terrible we don't recommend you trusting them with your pets. read more

Took my cat to this place and waited over 3 hours bc there is only one vet at this er clinic. She was in surgery. I get that. When the vet was out of surgery, the vet didn't even come in to exam my cat, Sammy. She sent in a nurse with an estimate on the cost to sign and without even examining her and only seeing a report that I brought in from my cats vet from 2 months ago, said "it sounds like a bladder infection." Duh. What would have happened if I didn't have that report? I told the nurse I wasn't signing anything and wanted the vet to actually examine my cat in front of me. The nurse returned and said the vet wanted to stay with the animal she had surgery on (I've seen 4 other staff members in the office that could have stood by that animal for 5 minutes)and the vet said she wanted to do an ultrasound - she never even saw my cat! My cat had a freaking fever, having problems peeing and when she does it has blood in it and the vet couldn't tear herself away for 5 minutes to examine my cat. The nurse then asked if she could take my cat back for an ultrasound. I insisted on seeing the vet to actually examine my cat in front of me, which she never did. The nurse returned again said the vet wanted to stay with the other animal. I missed 5+ hours of work to not even see OR speak to the vet, or her examine my cat. I was pretty pissed. I asked the nurse for a number/email to file a complaint bc this is ridiculous. Then shocker, the vet shows up. I don't understand why this is an emergency clinic and only one vet. I'll never take my pet there again. I was sent home with my cat, pain meds and kitty Valium for my cat and a script for prescription food. Oh, yeah...my cat did NOT have a bladder infection. She has crystals in her urine. I will say that it is mainly my fault for taking my cat there bc I have to use CareCredit credit card to pay and this is one of 2 er clinics here that take it. I was told the other place has a longer wait. read more

I hope everyone reads this story before EVER going here. I had the worst experience with Dr. Lorde at AEC. I have been a Vet Tech throughout my life and have never been talked down to, had the run around or been so mad at another veterinary professional in my career. Let me explain. I brought my 4 year old cat BB here after he was urinary blocked for an overnight stay with monitoring and fluids after already having a IV catheter and a urinary catheter in place surgically at a different hospital. After getting a quote for $300 for a 24 hour stay with monitoring and fluids overnight I said my goodbyes and dropped him off. He had been there for 20 minutes, I hadn't even made it home yet, before they called me saying his urinary catheter wasn't flowing and was probably blocked and needed surgery to replace it with a LARGER rubber catheter. I informed them that his bladder was FULLY expressed less than an hour ago so there wouldn't be any flow as his bladder was 100% empty. She then informed me that it was the wrong size and needed a longer more comfortable catheter and she was just looking out for the best interest and comfort of the patient. I called my primary vet and informed them off the new and the suggested that my cat be placed on fluids and see if the catheter flowed because he was empty and hadn't had any fluids to flow aka empty bladder. Dr. Lorde then backpeddled AGAIN and said that it might not be blocked but that he'd be more comfortable with a larger rubber catheter. I asked her how it would be more comfortable for my cat to have him put under anesthesia a second time that day just to replace something that was already working. After a back and forth with Dr. Lorde and having to FIRMLY state that I don't want my cat having a second surgery and to just have him get fluids for a few hours to see if the catheter is really blocked or he's just empty she finally conceded and said she'd call me back with a estimate for that. After getting a call and a quote for $600 (double what I was originally quoted), I informed her I was not comfortable leaving my cat in their care and wished to take him home and monitor him myself overnight and take him back to my primary vet in the morning for Fluid therapy, medication and continued care. She told me I couldn't get my cat back, and refused to release him to me. Excuse me? I've taken care of cats like this my whole career and am perfectly capable of watching my own cat for a few hours until the vet I trusted was open again and can continue care. Dr. Lorde's reasoning for not releasing my own cat to me was that she couldn't release him with a IV catheter in and a urinary catheter in. I informed her AGAIN that I was a veterinary professional myself and know the risks of taking him home and would be more comfortable caring for him myself. She again REFUSED to give me my own animal back. At this point I am in tears and furious. I call my primary vet again and inform her of the situation and said that I can sign a AMA (Against Medical Advice Form) and can take him home after that so the clinic is liable. Called Dr. Lorde back and informed her I would like to do so and she then again refused to give me my animal because of his catheters in place, I told her it made no sense to have both removed (painfully) just to have them reinserted first thing the next morning, it was unnecessary pain and stress to my cat to have to put him through that. Dr. Lorde again refused. I had to call my vet at 9:00pm to get them to call AEC and Dr. Lorde and basically tell them that I'm competent enough to care for my own animal and that he will be in my primary vets care in the morning. She finally had to concede. Drove 30 minutes to pick him up just wait in the parking lot for another 30 minutes for them to bring him out. When I finally get him, they put him in the front seat, set a "bladder flush bag" on top of his carrier, shut the door and walk away. They never had me sign an AMA, never gave me any discharge. He came home totally unwrapped and his cath line detached. Never again. read more

This place basically killed my 1 year old cat. I had her in about a month ago and told them all of my concerns the vet had listened to her her heart and looked into her gums but ended our examine because she tried to bite him, he had said it doesn't seem to be anything wrong she's probably pregnant and sent me home. she had feline disease and now it is to late to stop it or do anything to help. I wish I would have picked anywhere else the night I brought her in. read more

Had to bring my cat in because she could not stand up and move her legs. From the receptionist to the doctor I experienced so much compassion. We ended up euthanizing my cat and the compassion caused continued. We wanted to bury her and because it was the middle of the night they kept her there. Once we picked her up the staff was different and again so compassionate. I even got a hug from a staff member. The situation was awful but everyone made it bareable. Thank you Animal Emergency Clinic of O Fallon. read more

Dr. Samantha Kevin was calm and empathetic as we navigated our sweet Libby having a tummy bug. She was thorough and we felt like Libby was in great hands.

Been going there for yrs but never again. Dr. Hites was extremely rude & cruel. Her exact words were ' we need to muzzle him to administer meds into his IV , if we don't muzzle him & he bites me we will have to remove his head & send to a lab " I said he had his rabies shot & she got sarcastic. My dog was being uthenized I was already crying I could not believe she said that. Extremely unprofessional, heartless & I am reporting her. read more

The place was awesome. obviously it was not a good time by no means. went in cause my dog was having uncontrollable bowl movements to then deciding to put her to sleep. but the staff was very helpful and great with us. they did take a while to keep getting back to us but they were busy so we understoo. I will say one employee was very outstanding and went out of her way to help me and make sure I was okay. I'm not going to say any names but she does deserve some extra there cause even the little small things helped with that horrible experience so god bless her. read more

Agree with other reviews: avoid this place if possible. Seems as if someone could open another Vet across the street they would do really well. On a Sunday, I had to wait over two hours to just SEE a doctor. Can I simply pay, and get other things done, as there is nothing worse than waiting that long to see what needs to be done. My dog had a laceration on her head. So, they stitched it and put a drain in. After I signed consent I left her there and didn't pick her up till around 2-3 p.m. (for stitches and a drain) FF to Wednesday and drain removal. My dog had scratched the drain out, and I just wanted to make sure nothing of the drain was left, I talked to the tech (granted on the phone) and she talked about putting her under sedation again if I wanted and doing "exploratory" surgery which is obviously nonsense. I pulled her from their care and made an appointment immediately with her normal vet at Elm point as she deserves better care. AVOID if possible, I'm told Webster ER has a better system and this would have been a better option, as we live in St Charles. You can pay them and leave if there is wait time. (Again, it was a laceration that needed to be stitched so my dog was not critical but it needed to be fixed.) in addition, they nicked her scalp and ear area with the shaver, and I'm not happy about that. read more

My kid's one year old puppy had a fall down the stairs. Very traumatic experience for everyone. Her hip was dislocated. One of the only places open on a late Sunday night we brought her ASAP. They took amazing care of her over night. They adjusted her hip. Warned me about surgery if it happens again and most importantly the surprise bill was affordable. I've heard horror stories of $2000 bills for such emergencies. This was less than half that at $850. I am very please with this facility. They even called to check up on her. read more

We brought our dog in on a Sunday afternoon for an allergic reaction. The tech and vet were incredibly friendly and informative, and we were seen quickly. Our dog was given three injections, and they kept us for about an hour to monitor her swelling. The clinic had vending machines, a coffee bar, and restrooms available while we waited, which was such a nice touch! With an emergency vet, I expected a high price tag, but our bill was just over $200. We couldn't be happier with the quality and value of care, and will absolutely be recommending Animal Emergency Clinic to family and friends. read more

This Hospital is awesome!!! They don't overcharge being they're en emergency Vet. Also if anything happens within 72 hours of going you don't have to pay again if need to be seen. That's awesome they make that apparent right away!! So the poor doc was so sick and even with HIM being sick he was still amazing!!! read more

Went there on 12/16 at 7 pm. Was told to check in on phone. I called, someone said they'd be right with me to check me in, and was placed on hold for 25+ minutes and. I called on my other (work) phone to find out the issue, the person took down my name and number and said they'd call me right back to get me checked in. In the meantime, I called another vet practice after hours and got in right away. Now it's 2 days later and they never called me back to check me in. Do yourself a favor, don't go to this place. Even if they're understaffed they can at least check guy in!! read more

My golden mix was having seizures after vet hours. My vet did answer the phone and said to take Harry to this animal hospital. They are awesome. They promptly came out and carried Harry in on a stretcher. Dr was in contact with me right away with Harry's condition and plan of action. They got going on him right away. He was released the next day in perfect health with a bottle of meds. What was even more heart warming was when I couldn't get a refill for Harry right away, they gave me another 60 pills to hold him over until we could get his prescription filled. My dogs are my children and they treated them as such. God love that staff for how and what they do for our 4 legged kids. Elaine Bilyeu read more

After having to go in late we were floored at the compassion of Dr. Nagel. She was professional, understanding, loving, and we genuinely feel that she wanted what was best for my partners cat. I am a rescuer, and know a lot of people in the animal community and will be recommending her to anyone with an emergency. We can't thank her enough for what she did for us in one of the worst moments. TBH we ran in on our pajamas, vet records in hand, looking like a mess with a cat in a blanket. We were not judged, but heard. We were in tears at her kindness. Just thank you. From the bottom of our hearts. I'm really glad you're in the field. read more

This has to be the worse vet/emergency place around so if it can be helped do not take your fur babies to this.

My kitten managed to get a hold of a sleeping pill that was likely stuck under our stove for who knows how long. She threw up and thought I saw something white in there...20 minutes later she couldn't even stand up. I drove as fast as I could to get her there. I walked in and they took her limp little body out of arms as soon as I walked in and took her back. They gave me a high/low estimate and the cost was within those limits. Dr. Brown came out and talked to me, and then brought her back out to me because she needed to stay the night for treatment...he was very kind explained everything. Dr. Erbe update us twice the following day and also, very compassionate. I would highly recommend. For the negative reviews..maybe it depends on the vet...and the time of day. People have to realize that this is emergency clinic...so when I walk in with my kitten that is practically unresponsive...they will be seen before a dog or cat that needs stitches or threw up once or twice. It is just like an ER for people...the most life threatening cases get seen first...Also..yep, emergency clinics are expensive...they all are. So you really can't give one or two stars because you had to wait, or pay the fee that is on the very first piece of paper you signed...it's just not fair. I am an ICU nurse and bedside manner is great (all doctors don't have it) but in the end all that matters is if they help your fur baby. I have no doubt that my kitten very likely could have died last night with out their swift treatment. Sadly, I only remember Courtney by name but all of the ladies there that took care of her and watched over her were just amazing. Sweet Mina...came home the following day...back to her regular/playful self read more

They took very good care of my sick lab. They were compassionate, "Call any time. We will be glad to give you an update on your dog's health." And they did and were kind with my worries. This time of COVID makes an easy excuse to avoid other people. They took care of me and my dog while maintaining COVID safety precautions. Estimate was right on. There were no unexpected changes and I came home with a great care guide. I will recommend this clinic for emergency vet care. read more

"OH NO!!!! What happened to our precious puppy Fox? She has a huge gash on her side and she is bleeding...and it's 8pm at night when all the clinics and vets are closed!!!" That is exactly what I said when it happened this week. I looked online for help and found nothing but closed animal clinics, or clinics not willing to help since they were closing in an hour. I was terrified...until...I discovered "Animal Emergency Clinic" AEC O'Fallon. I sped that direction and was met with a very friendly and compassionate staff, caring and wonderful service and a bunch of animal lovers like me. Fox had a 1.5" gash one her right flank, it was pretty bad and I was not happy. They were able to take care of her on the spot, stitch her side, provide antibiotics and a prescription pain killer for a reasonable fee. Now, it's an emergency room, so the cost is going to be higher, but it's worth it when your puppy/kitty/tyrannosaurus is hurt badly. They gave me and upper/lower estimate and they were able to stay close to the lower estimate and save me some cash. Thanks for what you do, you saved me and Fox's day!!! read more

Our14 year old dog had been sick but got worse over the holiday weekend and we knew it was time to let her go. This was the only choice around us to take her to since it was a holiday weekend. We had called the day before to ask how much it would be. They asked us how much she weighed and told us it would be $113. We went there the next day and of course very upset, we were having our dog who had been part of our family for 14 years put to sleep. They tell us it will be $147. We told them we were told $113 the day before. They said sorry you were misquoted or you did not give them the dogs weight. My dog only weighed between 10-14 pounds. Well it's not like your going to just leave and wait until the next day and go somewhere else. We knew it was time and was not going to make my baby stay in pain another day. As soon as I paid they took her to the back to put a iv in and I was not able to go with her. She was back there at least 15 min or more and I could hear her barking. That made me even more upset. I have had a couple of dogs put to sleep before and I was always able to be with them the entire time. Anyway when we got her back and it was time the vet came in. I don't remember her name but she was very nice and compassionate. I am thankful for that. Some of the other reviews have said one of the vets there was not very friendly. I am glad we did not get that one. I am still upset about the price difference and for that I would not recommend or go back there. read more
