We have a Weim, this is our 3rd. They all have been wonderful guard dogs. Very alert, almost hyper vigilant sometimes. I don’t think anyone would break in if they heard or saw the way they’re charging the window/or door when a stranger arrives. They sound ferocious.
Supposedly they were bred to take down large game, so the potential is there, but I don’t think they’d have the strength of a Rottie or Doberman.
I know the dog would protect us, to the best of it’s ability, just how far that ability goes would be the question. I will say this, for some reason, maybe their coloring, people get spooked by the breed. We’ve noticed
that for years, and that’s at a time when the dog is being
passive just walking on a leash.
A lot of people mistake Weims for light colored Dobes. I knew someone who got a fawn Dobe with natural ears and passed it off to his homeowners insurance as a Weim - because many insurance company’s won’t insure homes with Dobes.
