I have 3 yr old dog and lately I have noticed she won't touch her food. I've been watching her closely this week and she's hasn't eaten in at least 2 days, she'll still play with me some but not as much as she used to and acts a little different. In the last few months we've been through a few changes like one of our other dogs died, we moved into an apt (she's all ways been inside tho) and my fiancee got a job in another city and has been gone. I'm not sure if I should try to change her food or encourage her more to eat the normal food.
