Old dog losing weight, can't get her to eat more volume; what can I safely add to her food to help her gain weight back?
is losing weight again, but her tests come out as normal as can be expected. Among her various other issues, she has a jaw condition that means she doesn't like to open her mouth or chew. I give her as much canned food as I can get her to eat, but she gets tired of eating after a while, and what she will eat over the course of a day is clearly not enough now.
She's got some food allergies (primarily beef); this is about the only canned food I can get on a regular basis that won't make her sick and lose even more weight. I checked, and the senior and puppy varieties have fewer calories than the adult, dratitall, so I can't just switch to a higher-cal version of the same thing.
Is there a good oil, perhaps, or powder maybe, that I can add to her food to help her gain weight back? What's good for old dogs? If it's too hard to eat she will just walk away, so it can't make the food too soupy or too chewy or sticky. I tried giving her some peanut butter yesterday--she used to like it--but it's too much trouble now.
She's in reasonably good shape all things considered, has even been playing more since we adopted another dog a couple of weeks ago--I think maybe the additional activity is burning too many calories.
