Meet the breeder
I'm the breeder behind Sergeant Mastiffs/muddy boots cocker spaniels and cockapoos located in Indiana. We have been breeding for about 10 years now. Our dogs are our family pets first. We put a lot of energy into raising puppies to ensure they grow up to be healthy, smart loving pets. Our puppies are raised indoors and well socialized with kids, noises and other dogs before leaving. We want to make sure they are confident and happy puppies when they go with their new families.
Q. & A. with Erin
Why did you start breeding?
Our first mastiff was named Sarge. He is the reason we fell in love with this amazing breed. He was such a huge part of our family and when he passed he left a hole that we knew only another mastiff could help heal. We decided that no family is complete without one of these dogs which is why we decided to start breeding them. Our love and passion for mastiffs has only grown over the years!What makes your program special?
Our program is special because raising our puppies is our full time job. Our puppies are handled daily from birth. They exposed to new smells and noises as they grow to ensure they are confident puppies. They are raised indoors and we start working on potty training and crate training while they are with us.What are the different breed sizes in your program?
Our Cockapoo puppies are standard size. Sizes will vary depending on the parent dogs.Where do your breeding dogs live?
They live in my home.

I have the most wonderful cocker spaniel puppy thanks in a large part to Erin at Sergeant Mastiffs/muddy boots. She is a healthy, well adjusted and happy little girl. She has been well socialized and loves everyone. I highly recommend these breeders for all the extra efforts they put into raising their dogs.
