My wife's POM has stopped eating her food. Her energy level seems to be ok, but she has lost 1/2lb over the last few months. Her coat doesn't seem to shine, and she seems sad. We are waiting on bloodwork from the vet, but she eats people food. She has been going to the bathroom ok, no vomitting or diahreah. We are starting to get very concerned. This little dog is the life of my wife, she will not be able to handle a loss.
