Antonio was very responsive and kept us up to date as we waiting our arrival of our new fur baby. Our little girl is healthy, happy, and beautiful! Grateful to have found Antonio!

I got my Border Collie from Antonio, and I couldn’t be happier. He is not only knowledgeable and dedicated but also genuinely cares about the dogs he raises. Even after bringing my pup home, he has stayed in touch and been incredibly supportive. Highly recommend!
