The dog has already got into the less welcome aspects of the Christmas spirit. I don't know WHAT he ate - or drank - yesterday, but at 3 o'clock this morning he was making vomiting noises outside the bedroom door. He obviously wanted us to share in his discomfort. He then retired to his basket for several hours, nursing what, in a human, would have looked like a hangover.
This is NOT the sort of Christmas spirit we want. I'd rather he would learn to sing carols properly, rather than howling. Or give the postman a kindly greeting rather than a snarling, territorial bark. (The tinsel on the postie's cycling helmet doesn't even help.) A little more goodwill would be good.
