Horace is now 15 and I suspect can't smell his food as well any more. He has always eaten dry food, his teeth are good, his health is good, but he has lost weight (from 12# to 10.5#) over the past few months, because he just doesn't want to eat anything but treats. Is it time to start feeding him canned food to supplement his dry food? I hate to see him wasting away. Any suggestions appreciated. I know we haven't much more time with him.
