Pet's info: Dog | Chihuahua (Smooth Coat) | Female | spayed | 12 lbs
My slightly overweight 3yr old chiweenie suddenly came up lame in one rear leg on Tuesday after we had been out. She will put weight on it and sometimes walks a few steps normally, but primarily holds it up. She will kick after urinating with the injured leg and stretches ever so delicately but fully extending the leg . What the heck ? This can't be a luxating patella can it?

It may be. She may have a soft tissue injury or some slight swelling at the knee which is causing the patella to luxate even though it has not been a problem in the past. Your veterinarian can most likely determine if that is the case by a physical exam. If her patella is loose and moving around, it is usually pretty easy to detect.
