I clean homes for my income and there is a Briard pup at one. I let him out of his crate when I can supervise, but after the second time of him seeing, barking at the vac I put him in his crate. He's fine in there and doesn't get wonky, just chills. Though I've found when I do leave him out(supervised) he destroys his toys or constantly is working on a rawhide. His owner over indulges him with so much....I'd never, ever let my dogs see his digs/toys. I felt bad that he killed a bottle crunch toy while I was there yesterday and wondered if it was my presence that made him want to shred it. Here is a photo of Henry!
