Testimonials
Our Australian Shepherd, Elvis, completed the Puppy Scholar training with Diamond K9, and it was a wonderful experience. He learned all his basic commands, and just as importantly, we learned the fundamentals of training and communicating with our dog. Now that Elvis is an adolescent, we’ve encountered reactivity issues, and I knew right away he needed to see Kati and her team again. I have full confidence they’ll help us get back on track!

Kati is an absolutely incredible trainer! We sent our French bulldog to her for 3 weeks of boarding for reactivity to other dogs. We’d gone through a few trainers before, so he had a decent foundation for obedience, but nothing to really enforce it. The e-collar changed EVERYTHING. Our dog is so calm and well-behaved around other dogs now. He walks so much better in heel. He had terrible recall before and now always comes when called. If any reactivity does start to come up, it’s a simple correction and very easy to bring him back into focus and calm. Kati and Joyce really walk you through all the steps at the go-home session. If you’re able to implement the structure and training, it will do wonders for your dog and set them up for success!
– Client
My dog went here for a three week board and train program and I am very happy with the results. She is now ecollar trained, comes when called, knows place, etc., but the biggest change is how this has affected our relationship for the better. She is more confident now and I trust her more as she continuously looks to me for direction. The trainers are wonderful and very comprehensive. When I picked up my dog they did a thorough training session for me as well. I loved that my dog stayed with Kati in her home at night and felt she was well taken care of. I would definitely recommend.
