lisajl has it correct - baking chocolate is the worst for dogs. No two dogs will react the same - it could range from mild seizures to coma. Milk chocolate will only cause (most) dogs to have an upset stomach.
It seems like the pug ate the most candy or at least is affected the most. Now that the vomitting has calmed down, the other end is starting up. She's sitting looking longingly at the water bowl - I keep telling her it's her own fault! She eats snow as soon as she goes outside. She'll be in her kennel for the night.
Last Christmas the cats knocked a platter of sugar cookies off the table and she pigged out. It took her a few days to recover from that episode. We work very hard to keep her weight down, so she'll be dieting for the next few weeks. Her sister (owned by friends) weighs 10 pounds more than she does. DH is adamant about keeping her weight at a healthy level. Pugs will eat everything!!
Wondering why you cant give her any water, that seems so cruel ?
