Harv will always try and steal food given half a chance and boy, is he quick!!! A few months back we had friends round for Sunday dinner (beef and all the trimmings), when my friend picked up her glass of wine this little golden dart shot towards her plate and then disappeared in the blink of an eye. We all peered at my friend's plate to try and work out what was missing - she was gutted because it was a yorkshire pudding!!
We have now found a solution - Harv has to have a spot to be told to sit - ie his bed. We move the bed into the dining room and tell him to lie down on it, we've done this now for a few months and he is finally going on his bed, without being told, when he sees us sitting down for a meal.
This works well, but I won't even go into the events over Christmas when we had little kiddies running round the house with handfuls of crisps and Iceland mini pavlovas - I'm afraid that was a free for all and I gave up trying to stop Harv pinching food and tucked into a bottle of wine instead!!!
