My Shih Tzu is limping, struggling to jump. What's wrong with her leg?

Updated On September 23rd, 2025

Pet's info: Dog | Shih Tzu | Female | spayed | 4 years and 9 months old | 210 lbs

My 4 year old shih tzu has started to limp on right hind leg. She's hesitant to jump up or go upstairs and the limp is far more noticeable when she first moves or gets up. When she walks or lies on her back the right hind leg falls in towards the left to the point of almost touching. What could this be?

Poor Mischa! It could be that she strained or tore a ligament, or she could be suffering from a condition known as a luxating patella. This is when the kneecap moves out of it's correct anatomical position, and it is common in toy and small breed dogs. I recommend resting Mischa for the next 48 hours. No running, jumping, or playing. Take her out to toilet on a lead only, and bring her right back in when she's done. If she still appears painful after this time, then I would take her into the vet for an exam. The vet can diagnose where the pain is coming from, and can dictate a treatment plan for it. She may also benefit from some pain medications, which the vet can prescribe. Please do not give her any human pain medications, as many are toxic to dogs and can be fatal if given.
