Plenty of ways to ensure, but here are a few: 1. All breeders represented here are USDA Certified & Inspected and those inspections keep the riff-raff out of breeding. 2. Breeders must have current Vet checks and current vaccinations. 3. Parents of pups must also be current on vaccinations, Vet checks and free of any congenital defects before they are bred. 4. Breeder's designated puppy-raising areas must be kept clean and available for inspection at any time. 5. All puppies must be dewormed every two weeks from birth according to AAHA & CAPC guidelines 6. All puppies must be home-raised with tender loving care & done with a abundant love of the breed. 7. All breeders must have 5+ years of experience with many of our breeders at over 20+ years experience. 8. Our pups are given premium kibble, delicious protein-packed supplemental meals & fresh spring water every day to ensure puppy growth targets.
