The problem is, we're having trouble keeping weight on him. He is like skin and bones. He gets fed 3 times a day, all mushy stuff. Senior feed watered into a mush, alfalfa cubes in mush form, sometimes applesauce just because he loves it, but he never seems to get fatter. This summer has been the worst, because the winter really did him in. He goes out daily and runs like a fruit (he is still soundish and will trot everywhere when he's happy, like after a bath).
He tends to eat more when we give him loads of attention, like he's doing us the favor of eating in exchange for grooming and scratching.
Anyone know a good way to help him put on weight?
