My dog has been sick for a few weeks and I had a bunch of test done on him last week, since I brough him home from the vet he hasn't;t eaten much, just maybe a few nibbles here and there. The vet suggested giving him some children's Gravol and adding some Garlic Powder into some food. She said Garlic Powder will increase his appetite. Does anyone know if this will work?? And how much should I give him considering he will MAYBE eat a few bites of food.
