Why are my senior dog's hind legs weak and wobbly, but no pain?

Updated On September 23rd, 2025

Pet's info: Dog | Pug | Female | spayed | 11 years and 4 months old | 22 lbs

My dog (10 yo female pug) has intermittent rear leg problems that started today. When it happens, her hind legs work but don't seem to have the strength support her body weight. The dog seems a bit confused, but gives no indications of pain when it happens and we can touch and rub her hind legs and haunches without her flinching, whimpering, or giving any indication of discomfort. Otherwise her temperament, eating and bathroom habits are normal.

Have Hopper examined by your veterinarian. Spinal x-rays may reveal arthritic changes that could cause low back pain and home end weakness. Pain management, physical therapy, swim therapy and/or cold laser therapy may all be options depending on the diagnosis.

    Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Chronic pain in hind legs is often related to arthritic changes in the hips, knees or lumbar spine. This is common problem in dogs and can be treated with pain killers, anti-inflammatory medications, food supplements, physiotherapy, acupuncture and more. Please, take Cooper to your local vets, he may need an x-ray of his back legs, pelvis and spine to find out what is hurting and then the treatment can be started.

    It's not normal for dogs to get weak in their hind end just due to old age. She could have arthritis in her hips or back that is causing the weakness. Luxating patella typically causes lameness in the affected limb and they will hold the leg up when it pops out, so I'm not sure that that fits. I would have her checked out by your vet, they may want to take x-rays of her hips and back to help determine what is going on.
