Meet the breeder
I'm Haley, the breeder behind Cain Kennels Mastiffs located in North Port, FL. We raise our dogs and puppies In our home with a strict desensitization program. It is important to us that our puppies are happy, healthy, and provided the best care while they are with us so that when they go to their loving homes, they have the best start possible.
Q. & A. with Haley
Why did you start breeding?
I began to show an interest In breeding because of my love for dogs at a super young age. I always thought it was beautiful to be able to provide a family with a loving pet and family friend with my puppies. I have grown and learned a lot of new things about breeding programs since the beginning , and I am excited to continue to further my education, experience and more!What makes your program special?
We spend several hours a day with our puppies. We even begin potty and crate training before they go home. We begin desensitizing with ENS at only 3 days old. Our puppies come with an awesome puppy care pack , a wonderful health guarantee, microchipped, UTD on shots and dewormings, a health certificate, super loved and from the best parents!What are the different breed coat colors in your program?
Our puppies include apricot, fawn, and brindle. Colors will vary depending on the parent dogs.Where do your breeding dogs live?
They live in my home.
