So, we have a 11-year-old Toy Poodle (he weighs about 15 lbs, so not small). His name is Gerbil (long story) and his whole life he's been picky about food. He would spend hours guarding his dish but not willing to eat it. There were some weeks where we had to force feed him every day to get him started (just a piece or two and than he would eat). We would boost his blood sugar with peanut butter and/or honey some days. We moistened his food and put yummy gravy or chicken or other foods on it to encourage him.
A couple years ago we took Gerbil to the vet for his teeth to be cleaned and they said he had an abnormality in his canine teeth that causes pain while eating. They pulled his top canines along with cleaning his teeth. It seemed to help for a little while, but now he's back to his poor eating habits. He has good energy, potties fine, and drinks.
The whole purpose of this was because I noticed that sometimes Gerbil will lick furniture when he seems to be feeling perhaps some discomfort. I read that it can mean health problems such as gastrointestinal issues. We plan on taking him to the vet for an over-all senior dog check-up soon, but I was wondering if anyone had any idea what kind of tests or questions we should ask.
He is drinking more than usual, skipping some meals (will eat food he likes, but not what is healthy for him. Maybe try a different diet? He is picky, even when we tried new foods). He has an old dog cough (the vet said most likely a sign of early stage congestive heart failure) and there is a lump on his throat we want to get checked out (he has fatty tumors elsewhere, but since it was so close to important things we wanted to be sure).
Thanks for any advice!
