MY 14 yrs old pom with no teeth is not interested in most of the food I try to feed her. She acts as if she's very hungry but then turns up her nose @ the food in her dish. I've tried meat (cooked & raw), warmed her canned food, added meat juice & gravy, & even feeding each bite by hand. I'm wondering if her sense of smell has diminished & that is contributing to the lack of interest. Any suggestions for additives that might entice her?
