Trixie started limping last night after a rough game of tennis ball on the hill down the street from our house. This morning, it was worse - during our morning walk, she hopped on three legs and struggled to do her business gracefully. Now the vet says her knee is officially sprained and she can only have bathroom breaks in the yard, on leash, for two weeks. No walks at all! She is so active, I am afraid she will lose her mind (and maybe I will too...) Any ideas from anyone who's had to enforce "rest" before??
