3 Maremma's at the moment. They keep the wildlife away from the farm animals and live in the barn, except for our oldest. She's semi-retired at 12 and spends most nights or days below -10C inside now. She was out one night at -25C this winter but was smart enough bed down in the straw in the barn.
I like the breed though, as I think they've had a few thousand years of natural selection in the mountains of Italy improving them for the job, and no Kennel Club garbage genetics influence.
It's almost like you have a wild animal helping you keep your livestock safe, as they take care of themselves, and aren't over active so they don't eat alot. They are a good farm dog and it would be cruel to have one in the city, as its only a dog to have with some acres and some animals for them to take care of.
