I have a male 2 year old newfoundland. He stopped eating 9 days ago and have had him to the vet full examination, nothing wrong. We had been away for 2 weeks but had him looked after by father in law. One of us came back I didn't. I stayed an extra week. Alfie was fine, eat while I wasn't home. Then Alan had to go away for 4 days and he stopped eating completely. Does anyone have a problem like this with their dog when they go away or leave them?
