Alfie (pointer) has been drooling loads in the past few days which is odd as he doesn't usually.  I've posted under this board as I wondered if it could be health related as it's started so suddenly.  Has anyone else got a drooly dog where it just started overnight?

Think he may have a mouth problem, something stuck in the teeth or may be a broken tooth or an ulcer in the mouth or throat. Get your vet to check him out.
