Junior gets leftovers, Sausage Biscuits, hash browns, the cheapest hamburgers I can get, home fries (French Fries are his favorite) and sometimes I will raid the buffet line for him. Turkey puts him to sleep!
He also loves beef gravy over his dry dog food, whatever it is this month. I almost never give him canned dog food. Once in a while he will get at the cats' food before they do and then he eats Fancy Feast.
And he's NOT fat at all. I walk him three or four times a day (or HE walks ME) which is good for both of us. We wrestle from time to time ("Kill the doggie!") and play with his ever-present ropes. The tennis ball gets squeezed some but we can't chase it very well in the truck and there's NO WAY he's getting off the leash in a truck stop.
