Why is my active 6-year-old Lab mix limping and won't bear weight?

Updated On September 23rd, 2025

My 6 year old labrador cross, who is very active, is unsteady and reluctant to put any weight on his rest left leg. He seems perfectly happy and still runs on it, which I've been moderating. He doesn't seem uncomfortable and is easing well, the Wells is how long this has been going on. Any ideas please?

Poor pup! In large breed dogs, joint problems are common, and it could be that he has torn or partially ruptured his cranial cruciate ligament, and/or done meniscal damage to his knee. I recommend resting him for the next 48 hours. No running, jumping, or playing. Take him out to toilet on a lead only, and bring him right back in when he's done. If he still appears painful after this time, then I would take him into the vet for an exam. The vet can diagnose where the pain is coming from, and can dictate a treatment plan for it. He may also benefit from some pain medications. Please do not give him any human pain medications, as many are toxic to dogs and can be fatal if given.
