Our dog has changed personality over the last few days and I don't know if something has perhaps gone wrong. It isn't obviously medical, or something we can show the vet but it is really strange.
Background, he is an old boy, 14.5, and over the last two years has become increasingly lazy, as you'd expect, sleeping most of the day, wanting only short walks. A few months ago he became occasionally incontinent and he has a collection of minor ailments, but none quite bad enough to cause him pain or be life limiting.
However, the last few days he has paced around the house constantly - round and round in circles, he might move room but then starts his circles again. I've tried taking him out a lot in case it was a UTI or something, but no other indications. He actually has his tongue hanging out, he's so unused to this level of exertion, he's been going three solid hours. Has anyone seen this in their elderly dog? Did it have a cause? How did you stop it (it might be driving me ever so slightly insane, I'm trying to work)!!
