Exceptional experience with Colorado Behavior Vets trainer, Eric Gillaspy: About 1 year ago, my (adorable) mini schnauzer puppy was completely out of control, diagnosed very early- on with severe anxiety & separation anxiety. His case was so extreme that his panic started the minute we left the apartment and he barked non-stop the entire time we were outside (epic high-pitched, very loud), at anything, everything and nothing and severely reacted to other dogs. In addition, he was hard to handle at home, never relaxing or resting, not eating his food etc... After a vet recommendation, I contacted Behavior Vets, and while waiting for our appointment with our new doctor, it was suggested that we start working with one of their professional behavior trainers. Eric was selected for us based on his years of experience and reputation for success with challenging dogs. Living in a busy downtown area and in an apartment with an interior entrance, we have multiple obstacles and distractions working against us, and I am a first- time dog owner with no experience with puppies let alone one with special needs. I was really feeling the doom and gloom, experiencing heavy complaints from neighbors, landlords & family members, it was going from bad to worse quickly. Fast forward, and Eric has been truly a blessing in our lives. He is a relentless and creative trainer who has expertly navigated us through numerous calming and engage/ disengage exercises, varying training environments and a series of 'hand over the leash' sessions where he and my dog worked 1-1. The results of his hard work and immense patience with a sincere goal to affect change in my sweet little dog have us currently at a place that I wondered if we would ever see. It's astounding to walk with my dog through our neighborhood of former 'triggers' and see him happily strutting with a stick in his mouth, not reacting to other dogs, people, air - just being a dog. The progress that we have seen while working with Eric is truly amazing. My dog and I are so much happier and less stressed, and I have gained a new skillset and mindset that help my confidence in leading and training my dog moving forward. We feel pretty lucky to have found him and highly and wholeheartedly recommend him to you and your family! read more

We rescued our first female chihuahua mix during COVID, and last year we ended up having to take in a female cattle dog/lab mix from a family member who was not able to care for her. Though things went okay in the beginning, unfortunately our cattle dog/lab mix ended up attacking our chihuahua twice with the first incident occurring in December of last year, and the second time was this past April. Luckily, with urgent attention Gracie was very well taken care of and healed completely after both attacks. However, we were still heartbroken and desperately needed assistance with how to handle Nala's (cattle dog/lab mix) behavior and aggression in order to better the situation for all of us. Since working with both Dr. Sidel and their trainer Eric G., Nala has come so far from where we started! Dr. Sidel was so friendly, professional, and absolutely amazing at analyzing her behaviors and offering a medicinal treatment plan that would help with stabilizing Nala's mood and help her brain get into more of a learning state. On top of the medicine, working with Eric G. has been such a wonderful experience, and we are so grateful to him for his patience and kindness with both us and our dogs! We unfortunately had a bad experience with a trainer in the past prior to Nala attacking our chihuahua Gracie, and Eric was such a breath of fresh air after that experience. We would absolutely recommend Behavior Vets and Eric G. to anyone who is looking for extra support, understanding, and most importantly an incredibly knowledgeable and compassionate staff who truly does care about your pups as well as you as a person. Since Nala has been on her meds consistently in combination with our training sessions with Eric G., my husband and I both feel that there has been a wonderfully noticeable positive change in Nala's behavior and interactions with Gracie. We cannot thank them enough for their help! read more

I found Behavior Vets through my regular amazing vet because I had concerns that my oldest dog was having a significant increase in anxiety and I didn't know if it was her aging, or something else. I'm a human medical professional, and I have exceptionally high standards for care, and I should mention that my dogs are my children. I was immediately impressed with the intake process, which was comprehensive and the staff that were responsive, caring, and warm...I found myself wishing that human offices had the same customer service... However, my enthusiastic review is for the professionals of Behavior Vets. Dr. Christensen is utterly amazing. Caring, funny, empathetic, she genuinely took the time to listen, examine our dog, and go through all of the options. She also helped us make choices on the path to consider and we developed a step approach with her. We were so impressed that we made an appointment with Dr. C to see our other dog who has significant dog aggression and since he is a herding breed that doesn't have a job (living in central Denver there isn't a lot of livestock...) she helped us with how to manage his issue through behavior modification and training. We highly recommend Behavior Vets-. Everyone in the organization from the front line staff, to the trainers, to the doctors are caring, loving professionals who want the best for you and your pets. read more

If I could give Eric G. more than 5 stars I would without question! I started taking my Pit Bull named Kitty to him when she was a puppy and now that she is just over a year, there is no other place I would take her! He has taught her so many good skills and knows what works for HER, which I appreciate so much. Being a Pit Bull, I worry about the judgement that other people might pin on her, just based off her breed. My girl is quite rambunctious, energized and needs A LOT of stimulus and work. She is a really good dog, friendly and listens pretty well but she is a tank and I'm always so worried that she is going to body plow herself into someone and hurt them. I've been a little lacks lately with her training and knew I needed to get her back in to see Eric. I am not exaggerating when I tell you, he is incredible when working with her, he can get her to listen and pick up training in a matter of minutes! It's unbelievable how well she learns from him, and I know with continued work, we can do it too! I love that he listens to exactly what is needed with your pet and develops an individualized training plan that is not only fun and rewarding, but works! I cannot express enough how much I love working with Eric, Kitty loves him too! read more

My dog, Thor started seeing Dr. Christensen at Behavior Vets because he was dog aggressive. Thor was especially reactive when walking on a leash. Dr. C noticed that Thor seemed to have chronic pain in his lower back so she referred us to Dr. Bartling at Animal Care Center of Castle Pines. Long story but we finally got Thor's pain under control. Once Thor felt better, we started training with Eric Gillaspy. Thor had practiced his aggressive behavior for years. Eric has been helping me learn to reteach Thor to walk on a leash without reacting. Eric has given me the confidence and tools to walk my dog. I am not sure what life would be like if we had not found Eric. I tried other trainers but no one was able to help. Eric has been a game changer. He comes to my house and we train in the Thor's environment. This was important to me. I recommend Eric to everyone who ask me about Thor's trainer. Eric is the best! read more

I am SO thankful for Dr. Sidel and Behavior Vets! Our dog is a rescue and after adoption, we realized that she had many behavior problems including dog reactivity and fear aggression. When my dog was 1 year old, she bit me multiple times and became very unpredictable. I had already spent a lot of time (and money) working with trainers, but I was worried that my dog was on a scary path and that she might not be able to stay with my family. I have a young child at home and our family vet mentioned behavioral euthanasia as an option to consider. Luckily, we were referred to Behavior Vets and WOW, my girl is a new dog! She is continuously building her confidence around new people, other dogs, and she's the most loving girl towards our family. At one time, I was truly afraid of my dog and now, she's such a loving and loved part of our family. Thank you Dr. Sidel! You have helped us save our sweet girl! read more

when I say that Eric has changed mine and my dogs lives I mean it! We were in over our head and totally unprepared with one of our pups and since going to Eric, it's been a complete turn around! He cares so deeply about animals and helps create a different and positive outlook on them. I understand my dogs so much more now and he has helped us so much and given us so many resources to make sure our babies are safe and happy! One our boys is incredibly scared of everything, but Eric has really helped change his world and he's becoming a much happier and trusting little man. I was so nervous about losing him, but now I am confident that he's gonna live a long and happy life where he won't be so scared and aggressive! Eric is the person to go to. I've never met someone so dedicated and passionate about animals! read more

Our foster german shorthair pup, Harvey, works with Jaime and Dr. Muhovich at Behavior Vets. Harvey had a rough start to his life and suffered from dog reactivity, guarding, nightmares, and leash aggression when he entered our home. We started working with Behavior Vets back in October 2021 to address these issues and get Harvey in the best position for his future forever home. Harvey is on a dual medication and training to help him become the best version of himself, and thanks to Jaime's training, he is thriving! Harvey is the sweetest pup and now knows his boundaries, how to address stressful situations, and how to have a lot of fun playing and adventuring with us. We are so thankful for Jaime's smart, caring, and positive training approach, and all of her help teaching Harvey how to live his best life! read more

Dr Maffeo was such a great and reassuring professional for our dog Murphy and us, as his caring owners. Murphy has had some aggression (we thought) and significant anxiety issues. The fact that she was able to see Murphy in all of his glory (including his response to a fake dog) in a large room that didn't feel like a vet office, was so amazing. She was able to tell us that his response was fear and not aggression; that was very reassuring to us. We have then met with Eric, the trainer, several times (both at the facility and at our home) and have learned so many helpful things to help make Murphy a more trainable and wonderful dog to be out and about with. We would highly recommend their services and look forward to continuing our training and relationship with them. read more

We've "graduated" from our dog training with Eric Gillespy of Behavior Vets, and want to give a shout out and thanks for the exceptional support he gave us and the skills and knowledge he communicated throughout our training sessions that left us and our doggie Jovie ready for our first 3 week roadtrip vacation together last fall that was a wonder experience! From our first visit on, Jovie developed a real affection for Eric and had fun working thru the instructions and repetitions in learning new behaviors and responses to her new surroundings with us. We know that Eric's work with us helped us develop our most meaningful dog-human bonding of our lives! We're forever grateful to Eric and the high quality resources Colorado Behavior Vets provides. read more

I took my dog here for medicine but she benefited most from the training with Eric. She was afraid and aggressive towards people and she had worked with a trainer before who helped her a lot but the first session with Eric she was able to take food from his hand. The second session she was wagging her tail at him. It has been 4.5 months and her behavior has improved tremendously. It is expensive and requires time and effort but it is so worth it. I enjoy my dog so much more and she no longer sees people and other dogs as threats. We still have work to do but she loves her training sessions and her practice sessions. I highly recommend going here first. Do not just try medicine. You must use a trainer. That is the most important part. read more

We adopted a loving and smart Springer who has no aggression but is fearful, anxious, noisy and obsessive. Dr. Sidel has been working on medication changes that are making life less scary, and Eric Gillaspy has been doing in-home training with us. Eric is amazing, he helps us understand Zach's needs and triggers, and provides fun games and exercises that positively reinforce calm responses. We are even loose leash walking now with only a harness. We love that Eric listens to how we live and share with our Zach, and works toward our goals. He will identify if we are reinforcing bad behavior but always shows us how to help Zach correctly. Thanks, Eric and Dr. Sidel, for helping Zach live his best life! read more

Working with Dr. Christensen and Evia Zack (trainer) has literally saved my sanity and my relationship with my dog Sadie. A big change in my life (moving to Colorado from California) left my dog anxious, afraid to be left alone and unsafe to walk. Sadie was so stressed and I did not know what to do. With the help of Dr. C and Evia I learned how to help Sadie adjust to her new home and feel safe when I left the house. We are walking again every day, safely and on a loose leash. I love Sadie so much and I will be forever grateful to this team of wonderful people for helping me and Sadie be happy in our home. I highly recommend them! read more

This Trainer is amazing. We have learned so much. He is clear and is full of information. I've had many dogs and been in training with all of them, Eric Gillaspy is my top choice. Show up ready to learn how to work with your dog. All positive. No harsh training. Dogs want to please and Eric gets that. If you want good solid training for you and your dog it's so worth it. I respect Eric because he's not training a dog out of fear but love and if your a dog lover like me you have found the perfect fit. Behavior Vets Colorado. Thank you Elizabeth Decker. read more

The doctors at Behavior Vets of Colorado are kind and compassionate, and have helped us enormously with our reactive dog. Five stars are well deserved. Eric Gillaspy, our assigned trainer, deserves 25 stars, at the very least. He is an empath who understands animals and their behaviors better than seems humanly possible. With Eric's help, we have learned so much about our dog's triggers and how to keep him below threshold. We are better dog owner's, and our dog is a better pet, thanks to Eric. read more

Eric was recommended to us by our vet when we got another pup earlier this year. We did the group classes which were great and now we have Eric coming to our home to address some individual issues with our very high energy puppy. Eric has been very helpful not only training our pup, but training us how to handle him in different situations. Eric is calm with our pup and our pup loves seeing Eric. Not only is Eric a wonderful trainer, he is a nice, kind person. We highly recommend him! read more

Eric is the best! I have a 6yo German Shepherd mix who has had issues with anxiety and dog aggression. After losing my other dog earlier this year I was worried Daphne would never be able to get along with a new housemate. Eric helped me introduce a puppy into my home & Daphne has never been happier! I was even able to take her off of her anxiety/behavior medications completely. Now both dogs are steadily improving on leash walking and obedience training :) read more

Janna and her team are a pleasure to work with. They are very knowledgable in implementing behavior plans to a wide variety of animals. Janna has visited our sanctuary several times and we are seeing improvements already! She is has introduced us very effective behavior plans that we will use to enrich the lives of our residents. I recommend working with behavior vets for all your animal behavior needs. read more

Dr. Christensen has been amazing helping treat our young lab for anxiety. She spent about 90 minutes with us the first visit gathering information and observing Sam, our interactions with him, and his overall behavior. She came up with a complete treatment plan. We have seen an improvement in his behavior. She is very responsive if we email her any questions. Highly recommend Dr. Christensen. read more
