We spent most of the rainy day indoors - grooming pups and mom in the garage. Melon and Naranja managed to keep them selves busy 😃

Verified owner · Sept. 2025
Marina was very nice, she was knowledgeable and was able to answer all my questions regarding diet and grooming quickly. She ensured that my visit to pick up my puppy was smooth and that all the paperwork was in order for my puppy to be ready to come back with me to her new home and family.
Health testing is one key piece of responsible breeding and is performed on breeding dogs to prevent the presence of heritable conditions in their puppies.
