Limping is a sign of pain and if there legs are uneven then one may be swollen if there was trauma or an injury or one may be small from atrophy from not getting used as much. At that age it may be a soft tissue injury from playing and jumping or it may be a genetic or growth problem such as panostitis or hip dysplasia. The best thing to do for today is rest him and do not let him run and play to make it worse. He does need a check by your vet to evaluate for these problems to see what medicines you can get to help him

    Poor Zeus! I recommend resting him for the next 48 hours. No running, jumping, or playing. Take him out to toilet on a leash, 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, which the vet can prescribe. Please do not give him any human pain medications, as many are toxic to dogs and can be fatal if given. Best of luck.

    He could have some arthritis in is joints, issue with his knee cap, partial cruciate tear, etc. You could put him on a joint supplement, like Dasuquin, and see if that helps. Otherwise, have your vet take a look at him. Your vet can take x-rays to help diagnose and then prescribe medications to help treat. He may need an anti-inflammatory and pain medications.

    If he is limping and painful on his front paw I recommend a veterinarians. The reason for this is they can dispense medication to help with pain. In the mean time I would recommend rest (like what you are doing) and only leash walks to go to the bathroom. I hope Remington feels better soon and thank you for using Petco Pet Education Center, formerly Petcoach.
