I know this is an old thread but my sweet Lexie is displaying the exact same symptoms. When i came home lastnight she was like this, and was perfectly fine, happy and energetic before i left. Now she yelped when picked up, won't come when called, just wants to sit around and not play which is not like her at all. I touched her all over to check for the pain but i don't know where it's coming from. I'll be taking her to the vet but i'm so worried, the only thing she has ever had is an ear infection, she's been very healthy and energetic all her life. She turns 6 in a few days, my poor baby what's happened
