Testimonials
Our dog Chevy is treated so well here. He is growing in terms of his reactive and anxious personality and we appreciate the grace they have for our furr baby. We used to do doggy day care but more recently use there boarding services. Call at least a month ahead and 2 or more for time around the holidays.
– Client
I am so so grateful to Oscar’s!!! From puppy classes to training to boarding, they have been exceptional in dog behavior/breed knowledge and how well they care for my fur kids. I have been using them for almost 5 years and cannot recommend them enough! Thank you OPR!
– Client
We had our first training this evening in puppy kindergarten with Kristina… Wow! I am not only inspired… but in awe of her knowledge base, her ability to read dogs, her genuine personality and her desire to connect with clients and their furry family member. We left after just one session with a packet of great information and goals for the following week.
