Hello everyone!

I have a 9 year old husky and very recently I'm noticing some behavior change. So a couple of things have been happening. I have just gotten into exercising so her exercise has at least doubled in the past few weeks. But it seems like shes eating less and being less active when we are not outside. She gets really excited to go on the walks and doesn't seem to be tired during them but when we get home she's pretty much done until her next walk.

I can't tell if she's sick, adjusting to the new exercise, or just getting old. Her eating less I find very concerning. I made her eat yesterday by mixing treats in with her food but I don't think she has touched her food since then.

Any ideas? Thanks in advance!
