Just thinking back to this time last year when ddog stole Santa's mince pies and spent Christmas day on a drop at the emergency vet. 
Unlike chocolate, there's no way of knowing whether your dog can eat raisins safely. Some dogs can eat a whole plate of mince pies (or whatever) and be fine, others could die after 3 or 4 raisins. This is probably old news for most people, but dh wasn't aware last year, and when I started a thread venting about bloody thief ddog, a few posters commented that they hadn't realised.
Merry xmas!
