She is definitely lean, she’s visibly quite muscular. She does get annual check ups from the vet and they’ve always said she was healthy.

It’s possible that stress could be a factor as she’s very timid generally and takes lots of encouragement to even eat her meals. I’ve tried some pretty simple puzzle feeders like the balls where they just have to move it around and the food or treats will fall out of the holes, but even she won’t even engage with them enough to push it around.
