I used to have a big dog growing up and we never knew dogs were not supposed to have chocolate. Or milk. I'd give her a piece of chocolate now and then, or mix her dry kibble with milk to make it more enticing
LOL. Or give her bones. She did have a stomach of steel and died at a really old age... NOW I know better and Yorkies are so small, seems anything bigger than a pea might be harmful for them...
