Just getting over the rescue spaniels tooth problems with associated big bills, and little other dog just been to vet. He has been offcolour last couple of days but eating, but as weekend looming didnt want to risk emergency vet visit. He has two nasty lesions in his mouth, which could be ulcers due to some plaque on his teeth, but could be something more sinister. Booked in for further investigations on Tuesday, teeth cleaning etc. but hes 14 and got a heart murmur as well, so Im really scared now.
