I'm sure he's going senile but this is one habit I really find hard to cope with. He is 9.5 and we've had him 8 years. He used to do this very occasionally when stressed, ie if he'd been in kennels but then stopped. Now he does it all the time - I have to be really quick to get to it first. He's always been a scavenger and wears a muzzle when out to stop him eating all sorts. Its hard with two toddlers and trying to stop him licking them and round the kitchen table.
Any ideas anyone?
He's had blood tests to check liver and kidney function which are OK.
