Is it normal for elderly dogs to get hungrier?
I have a 15 year old terrier cross. He has never been particularly food oriented but maintained a good weight. Over the last few months I've noticed his spine is more obvious, which I assumed was age related muscle wastage. In the last few days he's seemed hungrier. He usually has half a small tray of scrumbles wet food with some chopped chicken on top twice a day, a few treats, and has access to biscuits but doesn't usually eat many but I don't know if that's because he doesn't have many teeth. Tonight I've given him the whole tray because he was eating biscuits, and he ate the lot. Is this a thing in old age? I would've thought the opposite would happen?
