As you said nobody wants a huge hairy white house dog, and if you think they'd be hopeless working dogs and can't be 'yard dogs', then what other options are left?
The only other option is a "pet" that is ALWAYS confined.
I never said they would be "hopeless". I said
if you NEED a working dog.
The OP gives the impression the dog will have free range of 60 acres, which is probably fenced with 4 ft wire that will NOT contain a Pyr.
If a dog is obviously a Great Pyrenees chances are it has some
livestock guardian instinct, unlike
overly-popular breeds that have had all usefulness bred out of them by backyard breeders and puppy mills.
Buying a dog from a breeder is not an absolute guarantee that a dog will do the job it is intended for, and even the best dog is hopeless with bad/no training.
Many Pyrs
have had the instincts bred out of them. They are the most common LGD breed in the US, and a large number of them are crossbred with who knows what.
While it is a possiblility this dog could have the instinct, if you will notice, the OP has never mentioned owning ANY livestock, and if she does, THEY must also roam over the whole 60 acres
Buying a true LGD breed from a GOOD breeder with working dogs IS a guarantee, because most will be from long
lines of dogs with proven ability, and they will have experience on how to work out problems.
It will cost a little more, but you KNOW what youre getting.
I can give you five generation pedigrees on all my dogs, and if they dont WORK, I will take them back.
I've never had one returned.
Theres no way to know if that shelter dog has ever even SEEN any livestock.
Mine were born in a barn, and have never been outside the pasture
These are 12 weeks old and are doing "on the job training" right now:
