i have a 10 y.o husky.
the other day, and many times before this but never so severe, she was walking, and all of a sudden her back legs just seemed to give out from under her...like, she would fall over and kind of roll around. and i would have to sit her up and hold her for a minute until she was able to stand up again. and then it would happen 2 minutes later...
she doesnt seem to notice that it happens, which i guess is good because i dont think it hurts her or anything.
i really have no clue as to whats going on..
