Meet the breeder
I'm Liza V., the breeder behind Mineral Springs Mastiffs located in Peru, ME. We breed our dogs for health, temperment and quality. Once our females are cleared and health tested for breeding we find a stud dog of equal value. I personally meet my stud dogs checking for temperament and quality. Our puppies are created using Transcervical Insemination and delivered via scheduled C-section. The safest and best way to create these babies. ✅ We genetically health test our parents for degenerative myelopathy, canine multifocal retinopathy and progressive retinal atrophy all recommended by AKC. ✅ We do OFAs on hips, knees and elbows to make sure joints are sound and free of defect in our parents. ✅ We do cardiology clearance to make sure hearts are normal. ✅ We do opthamology clearance to make sure eyes are normal. Before our puppies go home they will have a clean bill of health from our vet, first vaccines, wormed, microchipped and have a 2 year health guarantee. We breed for temperament, quality and to better the breed. Our puppies are raised in our kid friendly home, exposed to all home life has to offer as well experience being groomed in a professional setting in my own personal shop.
