Today my Great Pyrenees went to get a follow-up appointment at the vet's. DH and I had a scheduling misunderstanding, and dog ended up in day care for half a day. Which is fine, we like him to be socialized with other dogs occasionally. The thing that had me sorta uneasy and considering a different vet/day care is that at this place they have about 100% turnover every 9 months or so. It's a big chain of vets, and they move the vets around frequently. The day care, who knows where their people go, they never seem to last all that long. Maybe the pay is lousy? But I'm SO annoyed right now. Either they don't know how to discipline big dogs or they don't care. Every time we've had him in day care, the past three times, he comes home and he's EVIL. We drop him off, and he is a good dog whose only instances of selective hearing occur in the presence of squirrels. When we pick him up, suddenly he's jumping, nipping, challenging, pulling on his leash, doesn't listen to a word we say. DH said the last time he was dropped off, right there in the play room a big Newfie tried to do the nasty to him. DH scowled at the lady (who is supposedly one of their trainers!) and she just shrugged and said, "it's a dominance thing, it happens." When I get him home and attempt to re-establish discipline, he clearly thinks that if he just stops for two seconds to give me a big smile, then goes back to being a jerk, it'll all be OK. Today both he and our other dog got bones. Per their usual antics, they had to steal each others' bones several times over, then wrestle over the same bone. To re-establish who was in charge of this rodeo, I took the bone they were wrestling over. The other dog, being good, immediately backed up and sat down. The Pyr, who had been in day care, turned around and bit me on the head. We're not talking, a gentle nip, I mean, "grrrrr!" *chomp* and I had to check to make sure I really wasn't bleeding. He got stood over and held firmly until he submitted, of course, and he did submit quickly, but What. The. Heck? How does he go from the sweet boy who pulls a sled, warms my feet and babysits chickens for me to giving me a good bite, in a few hours at the day care? Do dogs really learn that quickly how to misbehave? Does it honestly take only a few hours of non-discipline? Does it come from interacting with a lot of other dogs, many of whom are likely poorly trained? Or is this something squarely on the shoulders of the day care dog-sitters? Seriously, I am not a big person and when dogs that outweigh me decide to give me a real challenge, I am in big trouble. This isn't a chihuahua trying to nip my ankle, this is a Big Dog and the consequences for bad behavior are severe. If this is a thing I should expect from him playing with other dogs, then I need to keep him away from other dogs. If this is a thing I should expect from lousy dog-sitters, then I will find another dog-sitter service.
