Well, my husband has a Bernese Mountain Dog growing up that died a few years ago.
They are large dogs, but considering their size, they don't need as much exercise as other dogs. A well-bred Bernese is pretty docile.
They are EXTREMELY intelligent and need to be trained as well as having good mental stimulation.
As far as hair goes ... we have a Samoyed, and nothing anyone can say will convince me otherwise: Samoyeds shed more than any other dog on this planet. So, IN MY OPINION, a Bernese is nothing
when it comes to shedding!
Yes, they need weekly brushing, but they don't shed en masse
like the Samoyed does.
Considering you now live in Louisiana, take the heat there into consideration. Bernese like fairly cold weather and in the summer he should NOT be allowed to be outside for long periods of time and NEVER be allowed outside without water to drink.
When my husband gets home, I'll get him to say more about Puppe, his Bernese.
