We left our 5 yr old female lab with family while we were away for 2 weeks. In that time she refused to eat (only 1/2 cup total in 2 wks). They took her to the vet and diagnosis was depression. She is drinking water, but has lost a lot of weight and has no energy. We will be taking her to the vet here at home, but do you have any suggestions to get her to eat until then ?
