aggression

We are dog sitting (for an extended period of time) for our neighbor's dog who gets along wonderfully with our dog. They play outside all day but have not "lived together" til now. Twice now in the last new days - our dog has nipped this dog while we were giving them both a treat. They growl and bark and even yelped - they have played like this many times in the past both at our neighbor's house, our house and outside. ????
