Cosmo

Poor Cosmo has been hobbling around the house off and on.  One day, his legs gave out on him, and he couldn't even stand up.  Then a few minutes later he was fine and has been OK other than some occasional limping. .  Sometimes only bearing weight on 3 legs.  Poor guy - we're hoping it's not hip dysplasia. 

Update: June 14 - He's got an ACL injury.  He's got pain meds for now, and he'll go in for x-rays tomorrow.  Cross everything you've got and hope that it won't require surgery.
