Teddy is walking around all crunched up in the "poopy" position. He keeps looking back at his right back leg and trying to lick back there, but he won't let me touch it or even get close enough to look at it. And he's panting like crazy. He was ok this morning when I left for work, but then when my daughter got up for school he was acting a little weird and when she got home from school she found him acting this way. My vet can't see him till tomorrow, I don't know what to do.
