Thanks - got him to take most of it. Normally a can of sensitivity control would stop it in it's tracks but not yet
I always have a tube of diarsanyl just in case so started him on it last night too. I thought he was grand yesterday and the RC had sorted it but he was panting and grumbling at me last night and finaly (I'd been trying to coax him for ages) got up and followed me out to the garden when i shook my keys and well let's say it wasn't pretty! Same again this morning and he's been snoozing all day since - no more trips to the loo but he's only had 3/4 of a can of RC all day so nothing for him to get rid of. He's never been lethargic before when he had an upset tummy - he'd drink normally and be his usual self so keeping a close eye on him.
Our vets say not to starve them so the gut stays active/nourished - has anyone else heard that? I play it by ear tbh - see how he handles say a half portion and go from there.
EDIT - just to update he was up all night trying to get sick and had an accident in his bed with more blood so I took him to the vets earlier. If he doesn't improve over night they'll probably take him in to give him fluids. He's had about half a can of RC since this morning (feeding him small and often) and so far so good so hopefully he's on the mend and the medicine is kicking in. He got excited when i brought him home a new ball from town and was alert for a while then took it to his bed and went back asleep lol - saving it for later
