We had what was probably a mountain dog and maybe not even a cross except his coat seemed a bit thicker. We found him in a shelter being claimed as a rott cross when he definitely didn't look or act like it as he grew up. Finally after much wondering and guessing over his breed someone showed pictures of mountain dogs and it matched perfectly. The size, shape, ears, tail, color including the white down the front, and even personality. He was wonderful with all the animals. If he found baby kittens or rabbits he'd carry them to us without any harm except some slobber. He did start out chasing the horses as a puppy until my ornery mare decided she wouldn't stand for it and he quickly gave that up. Little guinea pig pups would follow him around the yard when we let them eat grass. My sister would clean her dwarf hamster cages and leave the hamsters in an open top container while she walked off to wash the bottom of the cage. We'd find the dog laying near the container guarding them from the cat. There wasn't any animal he wasn't good with and I used him as my 4-h dog project and took him to obedience and agility classes. The only annoying thing was he hated to be alone. We'd have to lock him in a stall when we rode the horses off property or he'd insist on following. He couldn't be in a different room from you or he'd whine and scratch at the door. He got rather annoying sometimes. We finally had him put down last year at 9years old after 2 cancer surgeries and some joint problems.
