Oh Pam, I'm so upset that Bella wasn't any better today...I hope the vet has some answers. Perhaps she did strain or sprain it?? I was thinking the same thing; maybe a combo. of Lymes and a strain??? I hope she/he prescribes some enteric coated aspirin or other anti-inflammatory for the pain. We'll all be waiting anxiously for your report. Please get well soon, beautiful Bellla. Star and Cody send you get well licks. And we loved your precious pictures; a little bittersweet, seeing Bella holding her leg up
