you should see another vet next time. dogs absolutely can get strokes, i lost a cat last year to two subsequent strokes. i don't want to freak you out, i hope your dog recovers well, sounds like the danger has passed

Hmm. Yeah. We're continuing to watch him. This would be the second "stroke" episode he's experienced in a week. The first time we went to a different vet. Who also cleared him. And then we went to another for the second episode. Documenting things as they happen. He is behaving normally atm.
