I'm looking to own a cattle farm in the near future, and while I already have a GSD, he's in training to be an SD. As such, I will need to get a dog that can live outside with the cattle and handle being a farm dog before a house dog first and foremost. This is mainly aimed towards knowledgable dog owners of the following breeds and/or knowledge of which breeds seems best regarding the situation.

Great Pyrenees are highly recommended for guard dogs of cattle, and normal don't venture out of the yard so they are more likely to stay with the cattle after chasing whatever foe out of the yard.

Agreed.

Pyrenees are best babies, ours just guarded chickens and the house, but they would chase vultures, coyotes, foxes, anything that got close

while we had them with the chickens, it's was like all predators vanished(minus hawks of course, they just swoop in), since we moved them to my mom's house, we see much more of everything again

I think about three of my neighbor's with cattle have Pyrenees as well

my boy Coda did quickly figure out how to open both the screen door and the main door to the house. it did have a horizontal door knob though. smart doggos. and he was a big ol lap dog.

definitely reccomend 👍

My horse trainer has a Pyrenees for her goats, and she too has said that every predator seems to have vanished. She still gets an occasional accident with the chickens when he is out away from home since he tends to wander but nothing too horrible.

I have heard (coming from livestock dog breeders and showing livestock myself) that they do tend to stray from home, so good fencing is recommended.

My second choice would be an anatolian shep. I have a half GSD half Ana and he is a fail GLD. (He chose to be an indoor dog and refused to stay in the barn). I wouldn't recommend a mix however, especially not with a GSD since the prey drive tends to be higher than a purebred.

Unless you want a dog to herd your cows, I would stay away from Collies, aussies and Cattle dogs. They were working breeding that just want to herd and nip at heels.
