How to choose?
A Reputable Breeder
Choose a reputable breeder instead of the pet store or a casual "backyard" breeder.
Ask to see the parents of the puppy you are interested in. It is suggested that you inquire if both parents were certified clear of hip dysplasia. Make sure the surroundings are clean and that the puppy is healthy. Look for the happy, outgoing puppy. You don't want a shy, emaciated or sickly-appearing pup. Make sure the coat carries a glossy shine, a sign of good health. There should be no discharge from eyes or nose, and a pup should stand up on strong legs and good feet.
Inquire about a breeder-buyer contract, which explains what is expected of you, the buyer, and of the breeder. Your pup should come from registered parents, should have a pedigree from the breeder, a health record showing when and what had been given in the way of inoculations and medication, and care and feeding instructions.
If you're buying a puppy, it should be at least 8 weeks old. Carefully bred and cared for Great Pyrenees puppies are not inexpensive. While prices may vary, people who sell pups for much less than the average for your area probably have not put as much time or care into the breeding or rearing of their pups.
Male or female?
This is a personal choice. The male is larger, and carries more coat, but they both show the same affection for, and protection of, their family. The bitch, unless spayed will come into season every six months, the first season is usually around a year of age. The decision as to which sex is yours.
