Since Monday, my dog won't eat her dog food. She'll eat her regular treats and tries to mooch table food, which she has always done, but won't eat her food. She is very active,her tail is erect when she walks, loves to ride in the car and my UTV, and doesn't seem to be sluggish. I'm totally at a loss as to why she all of a sudden quit eating her dog food. Anyone have any ideas of what might be wrong? I have not fed her anything that she hasn't always eaten and none of her regular stuff in any different quantity. Her "bathroom" trips outside seem normal too.
