It was an absolute pleasure working with Kayleigh and Bristol hills. They have been responsive and cared for the pups. Loved that the puppies were litter trained. Kitty has been an amazing addition to my home and she has her own fan club in the California Bay Area.

Kayleigh from Bristol Hills provided an excellent and heartwarming process for acquiring my new puppy. From regular updates to face time calls, I also appreciated them personally flying my dog out to me. I just wanted to say thank you for the easy-going experience and for my beautiful new bull mastiff puppy.
