Professional Dog Training Experts

The dogs that come to Dog University for training range from puppies learning basic obedience to dogs (of all ages) with aggression issues, and everything in between. Because we tailor our training curriculum to the specific needs of your dog rather than a set list of expectations, we recommend a behavioral evaluation before scheduling training, so we have an opportunity to come up with the best training program that we can for you and your dog.

Good help and great service; bring your dog here and you'll both learn a lot! I dealt with Joanna over the phone and email, and she was responsive, prompt, and friendly. In the office, I mostly spoke to James, the owner, and he was knowledgeable, honest, professional, and helpful. I have a senior dog, who is set in her ways, but they dealt well with her, dealt straight with me, and they gave us both practical and specific things to work on tailored to my situation and my dog. Like it says above, five stars.

Two years ago I adopted a full-grown female Rottweiler, sight unseen. It only took a day to realize that I was in over my head. She was dog aggressive and would not hesitate to knock me down and drag me across the street to fight with another dog. She weighed more than I did and I simply couldn't control her. Determined not to give her up, I learned that there was a trainer at Dog University who had an unusual ability to rehabilitate troubled dogs. What a difference! My Rottweiler is now sweet, well-behaved, and loved by all. I recommend Dog University without hesitation.

I have personally utilized James Oliver dog training for 2 of my dogs. One was for a newly acquired GSD that was acting aggressive. James conducted a home visit and I followed up with a one week board/training session. Many family members and friends were blown aways by the difference in my dog. She never acted aggressive afterwards and was a truly loyal companion. Second dog- small and scared! James helped me help her become more confident. It has taken a long time but she now let's men pet her. I have referred many people to Dog University and have complete confidence in their professionalism.
