I was basing his feeding on our previous 55lb dog who never ate more than a cup per meal even when offered and put herself through fasts a couple times a month.
We have increased Gim's food and started giving him extra stuff, like meat and veg on top. He seems to be happier, though he's always happy with food
He's also getting treat balls and kongs full of different stuff like frozen pumpkin and wet food.
We found his one ear had a mild infection too which has been flushed out now. He had a hard couple days, poor guy.
