I've noticed Indie can do this in the evenings, not after exertion or anything.
Last night he was breathing really really quickly, and his tongue was hanging out a bit too. He hadn't been exercising or running, and was well hydrated. He seems to have this quite often in the evenings, during the day he's fine, and breathes normally, maybe 30 resps a minute, but at night this happens maybe three or four times a week.
Should I be worried? He's been at the vet as recently as last week, and his heart is fine.
Shona :?:
