Salty AND oily, bad for dogs. Many processed foods, particularly fried and overly seasoned (and particularly spicy) foods are bad for dogs. So are cooked bones (they crumble and break into sharp splinters) and chocolate, raisins and grapes, and all forms of the onion/garlic family. Chives, green onions, onions, garlic... etc.
It's surprising how many things are bad for dogs and cats. It's best not to find out the hard way, with a trip to the vet.
