Many owners first notice arthritis as something small: a dog who hesitates before jumping into the car, takes the stairs one at a time, or needs a moment to get going after a nap. It’s easy to file these changes under “just getting older.” Often, they’re signs of osteoarthritis, a painful joint disease that is more common, and starts earlier, than most people realize.
Arthritis can’t be cured, but it can be managed well. Dogs whose arthritis is recognized early and treated with a combination of weight control, sensible exercise, and appropriate medication often stay active and comfortable for years.
Quick Answer: What Are the First Signs of Arthritis in Dogs?
Early signs of arthritis in dogs include stiffness after rest, slowness getting up, hesitation before jumping or climbing stairs, lagging behind on walks, and licking over a joint. Some dogs become irritable when touched. A veterinarian diagnoses arthritis with a physical exam and often X-rays, and it is usually managed with weight control, regular low-impact exercise, and pain medication.
What Is Osteoarthritis in Dogs?
Osteoarthritis (OA), also called degenerative joint disease, is a progressive condition in which the cartilage cushioning a joint breaks down. As cartilage thins, the joint becomes inflamed, the joint capsule thickens, and the body lays down bony spurs called osteophytes. The result is a stiffer, less stable, and painful joint.
In dogs, osteoarthritis is usually secondary, meaning something else set it in motion. Hip dysplasia, elbow dysplasia, cranial cruciate ligament rupture, kneecap luxation, and old injuries all change how forces travel through a joint, and the joint wears abnormally as a result.
Is Arthritis Only an Old-Dog Disease?
No. Arthritis is usually treated as a senior-dog problem, but research suggests it often begins much earlier. A 2024 study in Scientific Reports examined 123 dogs aged 8 months to 4 years and found radiographic signs of osteoarthritis in about 40 percent of them. Roughly a quarter showed clinical signs consistent with OA, yet their owners frequently hadn’t noticed anything wrong.
The Merck Veterinary Manual notes that although OA can be present in young dogs, clinical signs generally aren’t recognized until dogs are 5 to 13 years old. That gap matters. Early management can slow the disease and preserve muscle that is much harder to rebuild later.
Which Dogs Are Most at Risk?
- Large and giant breeds, especially those prone to hip or elbow dysplasia, such as Labrador Retrievers, German Shepherds, Golden Retrievers, and Rottweilers
- Dogs carrying extra weight
- Dogs with a history of cruciate ligament injury, kneecap luxation, fractures, or joint surgery
- Highly athletic and working dogs that put repetitive strain on their joints
- Older dogs, as joint changes accumulate over time
Small dogs get arthritis too; it’s simply easier to overlook in a dog that gets carried up the stairs. Hip dysplasia is one of the most common triggers in larger breeds, and our article on how environment and exercise affect hip dysplasia explains why the puppy months matter so much.
What Subtle Signs Do Owners Often Miss?
Dogs rarely cry out from chronic pain. Instead, arthritis shows up as changes in how they move and behave:
- Stiffness after rest that eases once the dog warms up
- Difficulty rising, sitting, or lying down
- Reluctance to jump onto furniture or into the car
- Taking stairs slowly, or avoiding them altogether
- Shorter walks or lagging behind
- Bunny-hopping with both hind legs, or a swaying gait
- Licking or chewing over a joint
- Muscle loss over the hips or thighs
- Irritability when touched, or less interest in play
- Restlessness at night or trouble getting comfortable
Video can be surprisingly useful. Record your dog getting up, climbing stairs, and walking, and show the clips to your veterinarian. Many dogs move very differently at home than they do on an exam table.
How Do Veterinarians Diagnose Arthritis?
Diagnosis starts with your observations and a hands-on orthopedic exam. Your veterinarian will flex and extend each joint, checking for pain, swelling, reduced range of motion, and muscle loss. X-rays confirm joint changes and help identify underlying causes such as dysplasia.
Many veterinarians use the Canine OsteoArthritis Staging Tool (COAST) to grade the disease from “at risk” to severe. Staging helps match treatment to the dog, because a young dog with mild signs needs a different plan than a senior with advanced disease.
Weight Control: The Most Powerful Treatment
If your dog is overweight, weight loss is the single most effective step you can take. Every extra pound adds load to already painful joints, and fat tissue itself produces inflammatory substances.
The evidence for keeping dogs lean is unusually strong. In a lifetime study of Labrador Retrievers published in 2002, dogs fed 25 percent less than their littermates stayed leaner, developed osteoarthritis later, and lived a median of nearly two years longer. Even modest weight loss has been shown to improve lameness in overweight dogs with arthritis.
Ask your veterinarian to assess your dog’s body condition score and set a daily calorie target. Treats count, and they add up faster than most owners expect.
How Much Exercise Should a Dog With Arthritis Get?
Rest feels like the kind choice for a sore dog, but inactivity leads to muscle loss and stiffer joints. Arthritic dogs usually do best with regular, moderate, low-impact exercise:
- Several shorter leash walks instead of one long outing
- Consistent daily activity rather than quiet weekdays and strenuous weekends
- Swimming or underwater treadmill sessions, which build muscle without pounding the joints
- Fewer high-impact activities such as repeated ball chasing, sharp turns, and jumping
Canine physical rehabilitation, offered by veterinarians and certified rehab practitioners, can add targeted strengthening and range-of-motion exercises tailored to your dog.
Pain Medications and Newer Treatments
Pain relief isn’t a last resort. Controlling pain allows dogs to stay active, which protects muscle and slows decline.
Veterinary Anti-Inflammatories
Dog-specific nonsteroidal anti-inflammatory drugs (NSAIDs) such as carprofen and meloxicam, along with the related drug grapiprant, are the foundation of arthritis pain management. Your veterinarian will usually recommend bloodwork before and during long-term use to monitor liver and kidney function.
Never Give Human Pain Relievers
Ibuprofen, naproxen, and acetaminophen can cause serious harm in dogs, including stomach ulcers, kidney injury, and liver damage, even at doses that seem small. Give only medications your veterinarian has prescribed for your dog.
Anti-NGF Injections
Librela (bedinvetmab), a monthly injection that targets nerve growth factor, a key driver of arthritis pain, was approved by the FDA in May 2023, and many dogs respond well to it. In December 2024, the FDA sent a letter to veterinarians about adverse events reported in treated dogs, including incoordination, seizures, and increased thirst and urination, with some cases ending in death or euthanasia. The drug remains approved, but the letter is a good reason to discuss benefits, risks, and monitoring with your veterinarian before starting it.
Add-On Medications
Veterinarians sometimes add drugs such as gabapentin or amantadine when one medication doesn’t fully control pain. Combining approaches is common and often works better than relying on any single drug.
Do Joint Supplements Work?
The evidence is mixed. Omega-3 fatty acids from fish oil, specifically EPA and DHA, have the strongest research support for easing arthritis signs in dogs, and they’re included in several veterinary joint diets. Glucosamine and chondroitin are widely used, but studies have produced inconsistent results.
Supplements aren’t regulated like drugs, so quality varies from brand to brand. Ask your veterinarian to recommend a product and dose, and treat supplements as an addition to weight control, exercise, and pain relief rather than a substitute.
| Approach | What It Does | Strength of Evidence |
|---|---|---|
| Weight loss | Reduces joint load and inflammation | Strong |
| Controlled exercise and rehab | Maintains muscle and mobility | Moderate to strong |
| Veterinary NSAIDs | Reduce pain and inflammation | Strong |
| Anti-NGF injection (Librela) | Blocks a key pain signal | Good, with post-approval safety reports to discuss |
| Omega-3 fatty acids | May reduce joint inflammation | Moderate |
| Glucosamine and chondroitin | Proposed cartilage support | Mixed |
Simple Home Changes That Help
- Rugs or runners on slippery floors
- Ramps or pet steps for cars, beds, and couches
- A thick, supportive orthopedic bed in a warm, draft-free spot
- Regular nail trims, since long nails change how a dog bears weight
- Toe grips or traction booties for dogs that slip
- Baby gates to block stairs when you’re not home
Conclusion
Arthritis is common, often starts earlier than owners expect, and is easy to mistake for normal aging. Watch for subtle changes in how your dog moves, keep your dog lean, and talk to your veterinarian early. Arthritis often shows up alongside other age-related problems, so regular senior checkups matter; our guide to dental disease in dogs covers another painful condition that older dogs tend to hide. With the right plan, most arthritic dogs can keep walking, playing, and enjoying life.
Arthritis in Dogs FAQs
Can arthritis in dogs be cured? No. Osteoarthritis is progressive, but it can usually be managed well enough for dogs to live active, comfortable lives.
How long can a dog live with arthritis? Many dogs live for years with arthritis. Life expectancy depends more on a dog’s overall health and how well pain is controlled than on the arthritis itself.
Should a dog with arthritis still go for walks? In most cases, yes. Short, regular walks on soft surfaces help maintain muscle and joint mobility. Your veterinarian can tailor the amount to your dog’s stage of disease.
What is the best treatment for arthritis in dogs? There isn’t a single best treatment. The most effective plans combine weight control, regular low-impact exercise, and veterinary pain management, adjusted as the disease progresses.
