There's something up with my dog. 8 years old, Tibetan Terrier.
About a week ago he had bad diarrhoea in the night. I presumed something he ate and he was back to normal within a day. He's still eating and pooing ok, he's just acting a bit strangely.
His day is usually: breakfast, long walk in the morning, mooching and sleeping through the day, supper, shorter walk in the evening, bed.
The last few days he's ok to go for a walk but not running around like he usually does - sometimes just stopping and not going any further. I've had to put him on the lead to keep him going. A couple of times in the evening, I've only got to the end of the road and he's turning round wanting to come home. At home, he can't seem to settle. He's either standing in the middle of the room, tail down, looking like he doesn't know where he is. Or, quite often, he's behind the sofa (this is usually only when there's fireworks). In the garden, he's doing a lot of digging, then lying in the hole, or squeezing himself behind a bush. The digging's not out of the ordinary, but it's usually to bury or find a chew, not to lie down.
I read that dogs can take themselves off to hide if they're not well. But he has no other symptoms - as I say, eating and drinking, pooing, tail is still up most of the time.
Any ideas? Should I be looking for something else? Or pop to the vet on Monday?
