One of our neighbors has a yellow lab and she did something to her hip (she likes to play in the lake and the rocks near it, so I think she may have slipped) and had to have surgery and be in a full-leg cast for 6 weeks. This family lives on the second floor and they had (OK, dad did most of it) to carry her down the two flights 2-3 times daily.So, I was walking my mutt last friday and he suddenly yelped and started limping. I tried to carry him home, but he insisted on walking, limping all the way back to the house.
Ended up taking him to the vet and turns out he tore his ACL (yup, just like athletes do) So, he gets excellent pain meds and anti-inflamatory pills for the next two weeks.
Oh, and no steps or jumping, which means *I* have to sleep in the living room, so he does not try to get on the bed.
It seems you have it easy.
