My dog has sudden, intermittent back leg and hip pain. What is it?

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Intermittent, painful lameness in dogs of her breed is often related to slipping patella, hip problems (for the hind leg) and sometimes elbow dysplasia (for the front leg lameness). A visit at your local vets is recommended. Full clinical examination should allow making the diagnosis and starting treatment, if required.

Wow, that is terrible! Unfortunately hip and joint problems are very common in large breed dogs, and it could be that they are suffering from hip dysplasia and/or joint problems such as a tear of their cranial cruciate ligaments. It may just be a terrible coincidence that they both aggravated this conditions around the same time. I recommend resting them for the next 48 hours. No running, jumping, or playing. Take they out to toilet on a lead only, and bring they right back in when they are done. If they still appears painful after this time, then I would take them into the vet for an exam. The vet can diagnose where the pain is coming from, and can dictate a treatment plan for it. They may also benefit from some pain medications, which the vet can prescribe. Please do not give them any human pain medications, as many are toxic to dogs and can be fatal if given.

The most common reason for lameness of a back leg in a small breed dog is a luxating patella - a knee cap that does not stay in place. Without examining him myself this is my best guess. I believe this would be the most likely issue and should be easy for your vet to diagnose. If it is getting worse then he probably needs surgery to correct it. The photos do not show anything outwardly abnormal. ( https://vcahospitals.com/know-your-pet/luxating-patella-in-dogs )

Thanks for using Petco Pet Education Center, formerly Petcoach! Lameness can be an indication of an orthopedic condition. This can be due to conditions such as a soft tissue injury, ligament conditions, a fracture and even a tumor. For this reason, I recommend that you have Jo evaluated by a veterinarian for further assessment and treatment. A veterinarian should be able to perform an examination and localize where the pain is so that further diagnostics like radiographs can be performed. Treatment will be highly dependent on what is causing the lameness. At the very least your veterinarian can start Jo on pain control medications to provide comfort. In the meantime, keep Jo's activity level to a minimum avoiding any jumping, running or rough playing. I hope you find this information useful in helping Jo. Wishing Jo a speedy recovery!

This depends on the age of your dog. In older dogs, this is a classic sign of hip dysplasia. In young patients with hip dysplasia, the hip joint is often "lax" or loose. The ball of the hip does not fit well into the socket. The actual formation of the ball of the hip joint may be improperly formed at the neck or head. Young patients often have the appearance of "bunny hopping" when running as this more evenly distributes weight across both back legs. They can also be intermittently lame, like your dog. They may have trouble rising or you may hear a click when he does or walks. We also see the weight being held more on the front limbs than the rear (leaning forward) when standing. In an older dog, shifting leg lameness is a sign of arthritis. Without further information, I cannot tell you what is causing this in your dog. Depending on the cause, medication can be useful to help the signs improve but a veterinary exam would be needed.

Poor Alfie! It sounds like he has a chronic problem. This could be related to an abnormality within the bone structure of his lower back, or hips. Sometimes an issue like hip dysplasia or a pinched nerve can show up like this. It would be less common, but an injury to his cruciate ligaments could also present this way. The only way to know will be to have Alfie visit his veterinarian. The doctor will palpate all his legs to determine the cause. The doctor may also need radiographs to look for changes to the bone. Until you get him into the veterinarian, he needs strict rest, so no walks, no running, no playing and try to keep stairs to a minimum. I hope this is helpful and please feel free to post any additional questions.

Two things come to my mind when I hear about rear legs giving way suddenly. I will address both separately. 1) Luxating patellas. This is a fancy name for loose knee caps. The groove the knee cap sits in is often shallow with smaller breed dogs, especially with the Yorkie or Maltese. The knee cap can slip in and out of place on its own quite readily in some dogs. It typically is not painful but can develop arthritis with time and this causes more irritation. What typically happens is the dog goes to step on the leg, the knee cap is not in place and they cannot place weight normally. Sometimes they do not place any weight on it, almost like a little skip, or they hold the leg up. The knee cap typically goes back into place on it's own or the dog kicks backwards and this puts it back into place. The arthritis can be managed with joint supplements or anti-inflammatories but typically the knee cap problem can only be fixed surgically and is only warranted in pets with severe trouble. 2) Bone injury -- without a known trauma, such as a fall or being hit by a car, a fracture is less likely. This causes the area to weaken and can suddenly become painful. It may not break but can be difficult to walk on. If this was the case, I would expect your dog to be painful if that area of his leg is touched. If you feel up and down his leg with pressure, does he seem painful? Do you feel any areas that are swollen?
