11 yr old female Jack weight loss but still energetic
Our soon to turn 11 yr old female Jack Russell, Molly, has always been a little on the plump side with an enormous appetite. Over the past several year or so she has slimmed down considerably, but generally has a decent appetite, though not like it used to be. She has barely slowed down, still loads of energy, still loves to run, still in charge of everything and everybody. One weird thing she started doing a few months ago was sneak away from our house and yard, where a neighbor was feeding her, mostly just bread. One time she came running back across a field with bread in her mouth. She's never done this kind of thing before, and we always provide her with plenty of good quality food.
Molls is beloved to us and we're just getting a little worried. What could be wrong, if anything? Is the weight loss (it wasn't sudden) just part of the aging process? Today I noticed for the first time she has some drainage from her eyes, looks like she's been "crying."
Thanks for any advice. I'm going to take her to the vet next week, but in the meantime would really appreciate some input.
