Before you call a Greater Swiss Mountain Dog breeder
- Health results for both parents. Good breeders test the parents for the health problems common in the breed (hips, eyes, heart, DNA tests) and show you the paperwork. The breed club lists the tests that matter.
- See the mother with the litter, in person or on a live video call, not only photos.
- A real breeder asks you questions about your home and schedule, and often has a waitlist.
- Never wire money or pay with gift cards or crypto before you have seen the puppy. That is how most puppy scams work.
