I didn't mean that exercising her would improve this particular issue, I was referring to your previous posts and why you seem to get so frustrated with your dog. Exercise will help those energy levels though. Even if you're doing as much as you can, she's clearly still a little ball of energy and could use more.
Regardless, like other have said, I think this is probably a reaction to the meds and/or any food changes if applicable.
You're probably going to have to wait it out. My male gets horrible diarrhea when he's on any kind of antibiotic, so it's not uncommon. Try giving some plain canned pumpkin to help ease her stomach but I bet this will get better once the meds are out of her system and she has readjusted.
As for the experience, I think it's awesome that you do so much to help animals in your community, but your posts speak for themselves...
