Arthritis is the likeliest culprit for weak hind legs. Larger breeds and overweight dogs are most likely to deal with arthritis as they age. Some signs of arthritis include difficulty getting up, lethargy, and pain when being pet or touched.^{[2]

This hormonal condition causes general muscle loss. The early signs of the disease include increased thirst and more frequent urination, but as it progresses, it causes muscles to deteriorate. Older beagles, poodles, and dachshunds are more likely to have this disease.^{[4]

Canine Degenerative Myelopathy: This uncommon genetic neurological disease is fatal, and unfortunately, there is currently no treatment available. If your dog frequently scuffs its nails and toes while walking, and seems to have spasms of weakness in its hind legs, this may be an early sign of the disease.^{[5]

1
Use Passive Range of Motion (PROM) exercises to increase muscle flexibility. With your dog laying on its side, lift one hind leg. Place a hand above the leg’s joint to stabilize it, and then use your other hand to move the lower portion of the limb. Gently bend your dog’s leg at the joint, and move it forward and backwards as far as it can naturally go. Repeat the exercise on the other hind leg, and then repeat it a few times each day.^{[8]

- PROM exercises decrease inflammation, help in the production of joint fluid, and stretch out your dog’s muscles. When done regularly, they can help mitigate arthritis, and bring back mobility to your dog.^{[9]

Practice sit/stand transitions to work out hind legs. These exercises often get used in physical therapy in order to improve strength and stability. Have your dog move from sitting to standing a few times in a row, and give it treats for doing so. If your dog is able, repeat this exercise twice a day.^{[11]

- Proper positioning is important for this exercise to be most effective. While sitting, your dog should be in a ‘sphinx’ position, with its body on the floor and paws close to it. Then, to stand, it should keep its front feet planted, while moving its hind legs forward.^{[12]

Walk your dog a few times a day to improve its strength. Exercise is critical for dogs to remain healthy, especially as they grow older. A short walk, even for 5 minutes, can help your dog regain strength. Keep an eye on your dog to make sure it isn't pushing itself too hard. Collapsing or showing signs of pain means your dog should take a rest.^{[13]

- Walking on an uneven surface can help your dog regain coordination and balance. Try getting your dog to walk on a mattress, which will allow it to use a different set of muscles while moving.^{[14]

- If your dog enjoys swimming, this can be a great way for it to build strength without putting pressure on the joints. Take your dog for a swim in a pool or non-moving body of water, but be sure to watch it carefully, in case it overexerts itself. If you see your dog struggling to stay afloat, immediately pull it out of the water.^{[15]

The variety of supplements available can be a little overwhelming, but many veterinarians recommend two products in particular: Glucosamine Hydrochloride and Chondroitin Sulfate. Although the science behind supplements has come under some debate, there’s a lot of anecdotal evidence that these products work. If you’re interested, talk with your vet about what dosage and combination might be right for your dog.^{[16]

Maintain a healthy weight to ease joint pressure. Diet is the best way to keep a dog from becoming overweight. Keep your dog eating nutritious, protein-rich food. Feeding your pet lean meats, such as chicken, and using veggies as snacks can keep your dog at a healthier weight. Dogs that are overweight or obese are more likely to experience hind leg weakness.^{[17]

- For a quick check to see if your dog is overweight, try the rib test. Run your fingers gently along the sides of your dog’s rib cage. You should be able to easily feel, but not see, each rib. If you can pinch more than an inch of skin and fat about the ribs, it’s likely time to try and reduce your dog's weight.^{[18]
