I can eat anything with them right on my lap and beside me and they never beg. I do share my cold stone ice-cream when we go up to Trader Joes. They LOVE "cream-cream" (roll the r's and pronounced like crem-crem) Got that from my husbands grandfather who was Italian.
Dogs mouth is cleaner than any humans for sure. How do you think they are able to lick wounds and heal them!
Humans have the nastiest mouths and we can get a serious infection from a human bite.
