Although cats are carnivores, dogs are actually omnivores, so a well-balanced diet of meat and vegetables is good for them. Spices are unnecessary, and simple prep is better. Typically a mix of vegetables and cooked meats in a base of brown rice will do the trick, although some foods are not okay, such as grapes, onions, chocolate, etc. You can get a list of foods that are toxic to dogs from your vet. Like people, they need small amounts of oils for coat, skin, etc. Be careful with fats though, as too much can lead to pancreatitis in dogs.
Also, contrary to the post above, do NOT use vaseline on the hot spots. Vaseline should NOT be ingested - it is a pertroleum based product. You might try some of the Burt's Bees products which for the most part of safe, even if ingested.
