He's doing his best to keep cool, has a cooling mat which he sleeps on or part on but I've noticed he's not been drinking much.
He's not panting or anything so I'm guessing he's coping- but I do worry.
I've got an old calpol syringe which I've loaded with water and have gently given him a few loads of water that way which he's accepted so all good I suppose.
I've left a few bowls of water around the house so there is plenty available.
