Our 3 1/2 female Newf Ziva has normally been a picky eater. We bought some new treats and she is the only one of the 3 who will eat them. The other two take them and spit them out. She snarfs them up! I thought bonus for her she gets more treats. Then I started thinking and her eating habits have been changing. She has started barking at us to hurry up and finish while we are making their meals. I mean loud barking. She also finishes first of the 3 when she used to eat more leisurely. She isn't drinking more or urinating more but should I take her into the Vet?
