Dog limping back leg sometimes fine sometimes bad
A pet owner asked our search engine this exact question. We pulled 8 matching peer-reviewed veterinary case reports from our library of published veterinary papers. Here's what they say — in plain English, with citations.
Plain-English synthesis
## What these cases have in common The cases primarily involve dogs experiencing hind limb lameness due to issues with the cruciate ligaments, muscle strains, or myopathies. The symptoms often include intermittent limping and pain, which can vary in severity. ## Treatments that worked - **Surgical repair of cruciate ligament**: In multiple cases (3 of 8), surgical techniques such as extracapsular stabilization or hybrid stabilization showed successful outcomes in restoring limb function. - **Surgical intervention for muscle injuries**: In cases of muscle strain or myopathy (3 of 8), surgical procedures like tenomyectomy or muscle resection resulted in improved mobility and resolution of lameness. - **Conservative management for joint issues**: Some cases (1 of 8) indicated that conservative treatment, including rest and physical therapy, could lead to recovery, although this was less common. ## Outcomes The treatments mentioned were generally successful, with several cases reporting complete or significant improvement in lameness following surgical interventions. However, some cases also indicated a risk of recurrence or partial recovery. ## Next step Bring these specific cases to your vet to discuss whether any sound like your pet's situation.
Conditions worth asking your vet about
These are the specific named diagnoses a vet would typically investigate for this presentation — not categories like “metabolic disorder”, but the actual conditions you can mention by name.
Cranial cruciate ligament rupture
A tear in the ligament that stabilizes the knee joint, often causing intermittent lameness that worsens with activity. Common in active dogs and can lead to arthritis if untreated. Diagnosis is typically through physical exam and radiographs.
Hip dysplasia
A genetic condition where the hip joint is malformed, leading to arthritis and pain. It causes intermittent lameness and is more common in large breed dogs. Diagnosis is confirmed with hip radiographs.
Luxating patella
Occurs when the kneecap dislocates from its normal position, causing intermittent lameness. More common in small breeds, it can be diagnosed through physical examination and sometimes requires surgical correction.
Lumbosacral disease
A condition affecting the nerves at the base of the spine, leading to pain and intermittent hind-limb lameness. Common in older large breed dogs. Diagnosis involves neurological examination and imaging like MRI.
Iliopsoas strain
A muscle strain in the groin area causing pain and lameness, often exacerbated by exercise. Diagnosis is through physical exam and sometimes ultrasound or MRI.
Osteosarcoma
A type of bone cancer that causes pain and lameness, more common in large breed dogs. It can cause intermittent lameness and is diagnosed with radiographs and biopsy.
Easily confused with: Immune-mediated polyarthritis · Tick-borne polyarthritis · Panosteitis · Degenerative myelopathy

A case of caudal cruciate ruptureCompanion Animal · 2018 · United Kingdom
A 10-year-old male neutered Border Collie, weighing 25 kg, was taken to the vet because he was limping on his left back leg. X-rays showed fluid in his knee joint, and during surgery, the vet found that a ligament in his knee was torn. They repaired the ligament using a specific surgical technique. When the dog was checked again 10 weeks later, he was no longer limping at all.

Gracilis or semitendinosus myopathy in 18 dogs.Journal of the American Animal Hospital Association · 1997 · United States
In a study of 18 dogs, most had a condition affecting the gracilis muscle, which is important for movement in the hind legs. These dogs showed a similar problem with their walking, where their strides were shorter and their paws turned in unusual ways. Some dogs tried medical treatments without success, while 15 underwent surgery to remove or repair the affected muscle. Although surgery initially helped with their limping, many dogs experienced a return of the problem within a few months, and additional medical treatments did not stop this from happening. The exact cause of this muscle issue remains unknown.

A report of the Maquet procedure for the management of cranial cruciate ligament rupture in a dog - a case reportSemina: Ciências Agrárias · 2017 · BR
A three-year-old male West White Terrier had a torn cranial cruciate ligament, which is a common cause of limping and joint problems in dogs. The veterinarian confirmed the injury using a specific test and took X-rays to assess the dog's knee. They performed a surgical technique called the Maquet procedure, which is a newer method that requires less time and fewer implants than traditional surgeries. After the surgery, the dog was able to put weight on his leg soon after and showed good improvement, with the bone healing well in about 63 days. Overall, the treatment was very successful.

Diagnosis and treatment of hind limb muscle strain injuries in 22 dogs.Veterinary and comparative orthopaedics and traumatology : V.C.O.T · 2005 · United States
This study looked at 22 dogs, mostly large breeds, that were diagnosed with muscle strain injuries in their back legs over four years. Many of these dogs came in with sudden lameness, and while most didn't have a specific injury reported, 21 had issues with their hip adductor muscles. The dogs were mainly diagnosed through physical exams, and in a couple of recent cases, ultrasound imaging helped confirm the diagnosis. They were treated with rest, physical therapy, a muscle relaxant called methocarbamol, and a non-steroidal anti-inflammatory drug (NSAID). Most dogs showed improvement or completely got better with this treatment, and of the 15 dogs that were followed up on, eight had no more signs of the injury, while two improved significantly and one showed some improvement.

Combined intra- and extracapsular stabilization for CCL rupture in a toy-breed dog: a case report.Frontiers in veterinary science · 2025 · South Korea
A 10-year-old Maltese dog weighing just 2.0 kg had a torn cranial cruciate ligament (a key ligament in the knee) and also had heart problems, which made traditional surgery risky. Instead of the usual surgery that involves cutting the bone, the veterinarian used a special technique that involved placing sutures inside the joint and anchoring them outside the joint without using a specific bone structure. After the surgery, the dog quickly regained the ability to use its leg normally, and there were no complications. This case suggests that this new method could be a safe and effective option for very small dogs with similar issues.
