As you can see from my yelp history, I am not into writing negative reviews, so mark my word, it takes a lot for me to have written this one. Nexgen K9 only gets two stars (which is the "could've been better" rating according to Yelp standards), but would have gotten the "not good" rating if it hadn't been for the sheer fact that I respect anyone willing to help train aggressive dogs. So that being said, my nonaggressive dog was sadly referred here by a wrong assessment by a vet employee who thought my dog needed this level of training. I didn't appreciate that Nextgen essentially lied to me about the pricing model they have when I made my appointment on the phone. I paid $400 bucks to have my dog assessed in a two hour session. The owner spent the first hour plus talking and filling out an intake form for me which could have easily been done beforehand or online etc. I also think they could have definitely taken down behavioral info beforehand then spent the time in a more constructive way assessing my dog. Over the phone I was told that I would be paying $400 for an assessment (two hour training/assessment) and I would be paying for a package of 3 lessons that amounted to something like $150-160 per lesson. I was very adamant over the phone with Samantha to make sure she knew that I was a single mom, and that I was very much wanting to know the cost of sessions going forward; I mean who the heck wants to pay $400 bucks and drive to Vallejo and give up their Saturday to find out the training is above their budget/too expensive. They spent an overall max 30 minutes of actually handling my dog/training. They put him on a spike/prong collar (don't remember the name but it was made in Germany and over $60 bucks) and tried a Martingale collar on him for just a second to see that it was not useful (well, my dog was used to harnesses so they didn't really give him a chance and quickly said he needed the more restrictive collar). They didn't ask if I was comfortable with this method or explain over the phone that their entire training depends on the use and purchase of e-collars that cost $249.99 that you are required to purchase to train with them along with a myriad of other items. I was told only at the end of my 2 hour appointment that the cost of the training would be $2000 for 8 lessons (that is $100 more per lesson than the quote over the phone) OR $3900 for two weeks at their Board & Train in Winters, CA., and I would have to purchase the following items as well: $55 for prong, $249.99 for their 400 e-collar, $35 for winged probes, $25.99 for walking leash, and $14.99 for martingale. When I showed my discontent with their communication over the cost (since I specifically mentioned over the phone that cost was very integral to my decision!) they backed each other up (Rob and Samantha) by saying "we said the minimum you may need is the three lessons but that after the assessment it could go up from there since we said the minimum is three lessons." I don't know what the heck they were saying, but I am sure that if I was their mom or wife they would go down to that shop and hella tell off the owners if this happened to their family. But you know what, it's ok for them --they got $400 bucks and they went about their day while I had to drive my ass back to Berkeley extremely saddened by this experience as I am really a woman of my word and they need to be upfront on the phone with people who are paying 400 bucks for their first assessment for their dog. I also didn't like that when I requested Rob, the owner, instead of Samantha I had to wait a couple more weeks for that appointment and I showed up to find out Samantha was the trainer anyhow. I had read some negative stuff online about her in another post, so I just wanted to play it safe and choose the owner. Samantha actually seemed fine and was the one mainly handling my dog. But in the end, she was dishonest with me on pricing in a very large way over the phone. She should have said the training would be $250 per lesson at a minimum of $2000 to start. I also didn't like that the owner put the ecollar on my hand and didn't turn it on to see if I felt it, and then turned it on later and to prove to me that it doesn't hurt. Either way, in the end, this place may be a great last resort for folks with dogs who are super aggressive as there a very few trainers willing to train these type of dogs, so kudos to them for taking on this venture, but they are not upfront with their cost system and that will eventually "bite" them, but for now, it bit me! What made it worse was they seemed like they could give a shit about losing my business or lying to me. I am sure they have had similar reactions from others. Either way, do your research above and beyond, and make sure to get the pricing in an email or written text about their costs. I think they should be ashamed of wasting my hard earned money. This place is not for nonaggressive dogs! PERIOD read more
