I’ve been working with Kathleen for the last three months with my 7 year old pit lab mix. Connor was a foster/rescue dog with reactivity issues especially with the random runner or even person that would waltz by. It’s been really insightful to learn new techniques and tricks to help boost Connor’s confidence and knock down the hyperness when needed.

Kathleen’s classes have been a great experience for us and our Golden puppy. I expect we will have an ongoing training relationship for sometime to come. Kathleen is an absolute pleasure and joy to work with. I think she understands dogs better than any other person I have ever met. Truly a dog behaviorist.. she just gets them. …maybe she was one in a past life☺️.. She has taught us so much about how to communicate with our dog. I have had many dogs before our current pup, but I don’t think I have ever really understood what my dog is thinking or why he is doing what he is doing like I do now. This is not your average doggy class……… This is more about behaviors, understanding why dogs do what they do and learning to respond to what your canine companion needs are and what they are trying to tell you. Every time we leave a class, we have a little something new that helps us understand each other a bit more. At six months, after attending several classes, we have a very well behaved golden retriever who sleeps through the night, who crates well, who behaves well around other people and animals, who walks very well on and off leash and is very responsive to us. His focus is us. Puppies are work!!.. It’s important to lay a solid foundation early on, then you will have a great dog that is easy and a pleasure to have in your life. Kathleen will help you lay that foundation and help you with any and all issues. She’s amazing!! I cannot say enough positive things about her, plus she’s just the kindest most real genuine human being I’ve met in a very long time! She’s good for the dog and she’s good for you too!

We hired Kathleen to help us work through some resource issues we were having with our two large male dogs. We are so grateful to have found her! She is helping us to better understand our dogs and how to help them be more well adjusted and joyful. She is nonjudgmental and a very clear communicator. We have also found her website's blog section to be super helpful and an inexpensive way to deepen our understanding and get ideas! We highly recommend Kathleen!
Kathleen is so knowledgeable and great at communicating the specific positive playful training that is needed for my dog. We have been working with our 3 year old dog and after the first training and exercises we went home with, we began to see a difference. I highly recommend Kathleen and Cosmic Dog.

It's been such an enjoyable time spent with our new pup and Kathleen at Cosmic Dog Training. She is so informative not just on methods and procedures, but also on the deeper explanation why the dog is behaving in such a way. She offers options, thoughts, and positive reinforcement on how to help us and our pup navigate their growth. She is very professional, prompt, and knowledgeable in helping us and our pup. She is highly recommended for any training needs you may have.
