We have a lab almost a year old. She wont eat out of her bowl. She will eat the dog food if we put it in our hand but she wont eat it out of her bowl. She will eat other treats and table food. She also seems very lethargic per her usual self. We have been watching to make sure she is still pooping but something just seems off. What should our next steps be? Should we try changing dog food? Could she be going into heat?
