Keeping your dog’s hips and joints healthy comes down to a combination of weight control, the right supplements, appropriate exercise, and medical treatment when needed. No single approach works as well alone as several strategies used together, and the best starting point depends on whether your dog is showing early stiffness or already dealing with diagnosed osteoarthritis or hip dysplasia.
Weight Loss Makes the Biggest Difference
If your dog is carrying extra weight, shedding even a modest amount can dramatically reduce joint pain. A study on obese dogs with hip and elbow osteoarthritis found that lameness improved significantly once dogs lost just 6 to 9 percent of their body weight. For a 70-pound dog, that’s roughly 4 to 6 pounds. By the time dogs in the study had lost about 9 percent of their body weight, the force measurements in their affected limbs returned to normal ranges, meaning they were walking more evenly and bearing weight more symmetrically.
Improvements showed up surprisingly fast. Dogs in the study began showing less lameness within two weeks of starting a weight-loss program, even before the biggest changes on the scale. This makes weight management one of the most effective, lowest-risk things you can do. Your vet can help you set a calorie target, but the principle is simple: feed less, choose a lower-calorie food, cut back on treats, and increase gentle activity as your dog’s comfort allows.
Glucosamine, Chondroitin, and MSM
Joint supplements are the most popular over-the-counter option, and there’s reasonable logic behind them even if the clinical evidence in dogs is still limited. Glucosamine supports collagen production in cartilage and has mild anti-inflammatory properties. Chondroitin sulfate works differently: it blocks enzymes that break down cartilage and joint fluid. Together, they help produce the building blocks your dog’s body uses to maintain and repair cartilage.
There’s no firmly established therapeutic dose for glucosamine in dogs, but chondroitin is generally suggested at 15 to 30 mg per kilogram of body weight. Most commercial joint supplements combine both ingredients (and often add MSM, which may further reduce inflammation), so check the label to see if the amounts fall in a reasonable range for your dog’s size. These supplements tend to be very safe, but they work slowly. Expect to wait four to six weeks before seeing any noticeable change, and they’re most useful for mild to moderate joint issues rather than severe arthritis.
Omega-3 Fatty Acids From Fish Oil
Fish oil is one of the best-supported supplements for canine joint inflammation. The active components, EPA and DHA, reduce the production of inflammatory molecules in the joint, which translates to less swelling and pain over time. Colorado State University’s veterinary hospital publishes dosing guidelines specifically for dogs with osteoarthritis, based on metabolic body weight. A few reference points from their chart:
- 20-pound dog: up to 1,623 mg combined EPA/DHA per day
- 50-pound dog: up to 3,227 mg combined EPA/DHA per day
- 80-pound dog: up to 4,591 mg combined EPA/DHA per day
These are maximum doses. Starting at about a quarter of these amounts and increasing gradually helps avoid digestive side effects like loose stools. Read the label carefully: you need the combined EPA and DHA content, not just the total “fish oil” amount. A standard fish oil capsule sold for humans often contains only 300 mg of EPA/DHA per 1,000 mg capsule, so larger dogs may need a concentrated veterinary formula to hit therapeutic levels without swallowing a fistful of pills.
Underwater Treadmill and Low-Impact Exercise
Exercise is essential for joint health, but the type of exercise matters. High-impact activities like jumping for frisbees or running on hard surfaces can accelerate joint damage in dogs with hip problems. Low-impact movement, particularly in water, builds muscle around the joint without stressing it.
Underwater treadmill therapy is one of the most effective options. Buoyancy reduces the load on painful joints while the water’s resistance makes muscles work harder, strengthening the support structures around the hip. A typical program involves 20-minute sessions twice per week for five consecutive weeks. The physical properties of water provide benefits that land-based exercise simply can’t replicate, which is why underwater therapy is specifically recommended for dogs dealing with pain, obesity, or degenerative joint disease.
At home, leash walks on soft surfaces (grass, dirt trails) are a good daily option. Swimming in a pool, lake, or calm body of water works well too, as long as your dog can enter and exit safely. The goal is consistent, moderate movement rather than intense bursts. Short walks twice a day are better for joints than one long weekend hike.
Anti-Inflammatory Medications
When joint pain is moderate to severe, your vet may prescribe a nonsteroidal anti-inflammatory drug (NSAID). These medications block the enzymes that produce inflammation and pain in the joint. Several are designed specifically for dogs, and they vary in how precisely they target inflammation versus affecting other body systems like the stomach and kidneys.
NSAIDs can be very effective, but long-term use requires monitoring. Your vet will typically run blood work before starting treatment and recheck periodically to watch for changes in liver and kidney values. Signs of trouble at home include vomiting, decreased appetite, dark or tarry stools, and increased thirst.
A newer option is a monthly injection that uses a monoclonal antibody to neutralize a specific pain-signaling protein called nerve growth factor. In a clinical trial comparing this treatment to a traditional NSAID, both groups showed significant pain reduction, with the antibody group averaging a 19.7-point improvement on a validated pain scale versus 17.1 points for the NSAID group. The difference between the two wasn’t statistically significant, meaning they performed comparably. Side effects with the antibody were uncommon, though increased thirst (and associated increased urination) has been identified as a rare reaction through post-approval monitoring. This option is particularly useful for dogs that can’t tolerate oral NSAIDs due to kidney or digestive issues.
Injectable Joint Protectants
A prescription injectable called polysulfated glycosaminoglycan works differently from pain medications. Rather than just reducing symptoms, it targets the disease process itself by inhibiting cartilage-destroying enzymes and supporting the joint’s repair mechanisms. The standard protocol is an intramuscular injection given twice weekly for up to four weeks (a maximum of eight injections total), dosed at 2 mg per pound of body weight. Many dogs then receive periodic maintenance injections. This treatment is most effective in the earlier stages of joint disease, before cartilage loss becomes severe.
CBD Oil
A Cornell University study found that CBD oil at 2 mg per kilogram twice daily significantly decreased pain and increased activity levels in dogs with osteoarthritis. Both owner-reported scores and veterinary assessments confirmed the improvement. No behavioral side effects were reported, though blood work did show elevated alkaline phosphatase (a liver enzyme) during treatment. The clinical significance of that enzyme change isn’t fully understood yet, so periodic blood work is a reasonable precaution if you use CBD long-term. Look for products with a certificate of analysis from a third-party lab, since the CBD pet market is poorly regulated and actual contents often don’t match the label.
Surgery for Severe Hip Problems
When conservative treatments aren’t enough, two surgical options are most common for hip problems in dogs.
Total hip replacement is the gold standard. The damaged ball and socket are replaced with artificial components, and studies show that nearly all treated limbs recover normal function. Gait analysis in dogs after hip replacement found that the operated limb returned to pre-disease function within about four months. Dogs typically begin partial weight-bearing within two weeks of surgery and resume normal activities within several months to a year.
Femoral head ostectomy (FHO) is a less expensive alternative where the ball of the femur is removed entirely, and the body forms a “false joint” from scar tissue. It has a reported success rate of about 93 percent, but the outcomes are more variable. Studies have found that 75 percent of dogs after FHO still had some muscle wasting, 74 percent had a restricted range of motion, and about a third experienced pain during passive movement of the joint. FHO tends to work best in smaller, lighter dogs and is often chosen when hip replacement isn’t financially feasible or when the dog’s size makes it a reasonable option. For larger dogs with significant hip disease, total hip replacement generally delivers a better long-term result.
Combining Approaches
Most dogs with hip and joint problems do best with a layered strategy. Weight management and fish oil are good foundations for virtually any dog. Adding a joint supplement is low-risk and may help maintain cartilage over time. Low-impact exercise, especially underwater therapy when accessible, builds the muscle support that takes pressure off damaged joints. Medications or injections can then be added based on severity, and surgery reserved for cases where the structural damage is too far advanced for conservative management to keep your dog comfortable.
