What Is Osteoarthritis in Dogs?

Osteoarthritis in dogs is a common long-term joint condition that can affect comfort, movement and quality of life. It is especially common in older dogs, but it can also develop in younger dogs after injury, joint problems, or repeated wear and tear. The good news is that, with the right support, many dogs with osteoarthritis can continue to enjoy a happy, active life.

In this guide, we explain what osteoarthritis is, the signs to look out for, how it is diagnosed, and the treatment and mobility support options that may help. If you are concerned about your dog’s movement or joint health, it is always best to speak to your veterinary surgeon as early as possible.

This article is intended for general guidance only and should not replace professional veterinary advice. If your pet is unwell or showing concerning symptoms, please contact your veterinary surgeon.

What is osteoarthritis?

Osteoarthritis, sometimes called arthritis or degenerative joint disease, happens when the smooth cartilage inside a joint starts to wear down. Cartilage acts like a cushion, helping the bones in a joint move smoothly against each other. When this protective layer becomes damaged, the joint becomes inflamed, stiff and painful.

Over time, the body may also try to repair the joint by forming extra bone around it. Unfortunately, this can make the problem worse by reducing movement and increasing discomfort.

Osteoarthritis can affect any joint, but it is often seen in the hips, elbows, knees, shoulders and spine. Some dogs develop it because of age-related changes, while others are more at risk because of:

• Hip or elbow dysplasia
• Cruciate ligament injuries
• Previous fractures or trauma
• Excess body weight
• Breed-related joint problems
• Developmental orthopaedic conditions

Which dogs are most at risk?

Any dog can develop osteoarthritis, but some are more likely to be affected than others. Larger breeds, older dogs, overweight dogs and those with previous joint injuries are commonly at higher risk. Breeds known for joint issues, such as Labrador Retrievers, Golden Retrievers, German Shepherds and Rottweilers, may be more prone to developing arthritis as they age.

That said, smaller dogs are not immune. We also see arthritis in small breeds, particularly if they have had kneecap problems, spinal issues or past injuries.

Symptoms of osteoarthritis in dogs

The signs of osteoarthritis can come on gradually, which means they are sometimes mistaken for “just getting older”. In reality, slowing down is often a sign that a dog is uncomfortable.

Common symptoms include:

• Stiffness, especially after rest or first thing in the morning
• Limping or lameness
• Reluctance to jump, climb stairs or get into the car
• Slowing down on walks
• Difficulty getting up from lying down
• Reduced interest in exercise or play
• Changes in posture or the way they sit
• Muscle loss, especially around the back legs
• Licking at joints or sensitive areas
• Irritability or changes in behaviour due to pain

Some dogs become quieter and sleep more, while others may seem grumpy when touched in certain areas. Cats and small pets can also develop arthritis, although the signs are often more subtle. If you have other pets at home, you can browse our collections for cats and small pets for general healthcare support.

When should you contact your veterinary surgeon?

It is important to contact your veterinary surgeon if your dog is showing any signs of pain, stiffness or reduced mobility. Early diagnosis can make a real difference, as treatment may help slow further joint damage and improve day-to-day comfort.

You should seek veterinary advice promptly if your dog:

• Has a sudden limp
• Seems in significant pain
• Cries out when moving or being touched
• Stops eating or becomes unusually quiet
• Has weakness, wobbliness or collapsing episodes

These signs may not always be due to osteoarthritis and could indicate another problem that needs prompt assessment.

How is osteoarthritis diagnosed?

Your veterinary surgeon will usually start with a full history and physical examination. They may ask when you first noticed changes, whether the problem comes and goes, and whether certain activities make it worse.

During the examination, they will assess your dog’s gait, joint movement, muscle condition and signs of pain. In many cases, X-rays are used to look for changes within the joints. Sometimes sedation may be needed so the joints can be assessed more comfortably and accurately.

Not all dogs with arthritis show dramatic changes on X-rays, and sometimes the level of pain does not perfectly match the imaging. That is why your vet will consider the whole picture, including symptoms at home.

Treatment for osteoarthritis in dogs

There is no single cure for osteoarthritis, but there are several ways to manage it well. Most dogs benefit from a combination of treatments rather than one approach alone.

Pain relief and anti-inflammatory medication

Many dogs with osteoarthritis are prescribed pain relief, often in the form of anti-inflammatory medicines. These help reduce inflammation within the joint and improve comfort and mobility.

Some dogs may need additional pain relief alongside anti-inflammatory treatment, depending on the severity of their condition. Prescription medicines should only be used under veterinary guidance, and you should never give your dog human painkillers unless your vet has specifically told you to do so, as many are dangerous to pets.

If your dog has been prescribed treatment, you can find information on ordering safely through our prescription medicine guide, browse dog prescription products, or read our prescription FAQs.

Weight management

Keeping your dog at a healthy weight is one of the most important parts of arthritis care. Even a small amount of excess weight places more strain on sore joints. If your dog is overweight, a carefully managed weight-loss plan can significantly improve mobility and comfort.

Your veterinary surgeon or veterinary nurse can advise on the right body condition for your dog, suitable feeding amounts and whether a joint-friendly diet may help. You can also explore our range of dog food and treats if you are reviewing your dog’s everyday diet.

Joint supplements

Some dogs may benefit from joint supplements as part of their long-term support plan. These may include ingredients such as glucosamine, chondroitin, omega-3 fatty acids, green-lipped mussel or other joint-supporting nutrients. While supplements do not replace prescribed pain relief when this is needed, they can be a helpful addition for some dogs.

You can browse our dog joint care range, dog supplements, and our premium supplements collection if you are looking at ways to support your dog’s mobility alongside veterinary advice.

Exercise and physiotherapy

Gentle, regular exercise is usually better than occasional intense activity. Short, steady walks can help keep joints moving and muscles strong without overloading the body. Swimming or hydrotherapy may also help some dogs, especially if recommended by your vet or a qualified canine physiotherapist.

It is often best to avoid:

• Sudden bursts of high-impact exercise
• Repeated ball chasing
• Long walks on difficult terrain if your dog is struggling
• Weekend-only overexertion after a quiet week

Your veterinary surgeon may also suggest physiotherapy, rehabilitation exercises or referral to a mobility specialist if needed.

Mobility support at home

Simple changes at home can make a big difference to dogs with osteoarthritis. The aim is to reduce strain on painful joints and help your dog move around more safely and comfortably.

Helpful home adjustments

• Use non-slip rugs or mats on hard floors
• Provide a supportive, well-padded bed in a warm area
• Use ramps for cars or steps where appropriate
• Keep food and water bowls easy to reach
• Try a harness for extra support on walks
• Keep nails trimmed to improve grip

Supportive accessories can also be useful for some dogs, especially as their mobility changes. You can browse our dog accessories collection for practical day-to-day support items.

Can osteoarthritis be prevented?

Not every case can be prevented, but there are sensible steps that may reduce the risk or help delay progression:

• Maintain a healthy body weight throughout life
• Feed a balanced diet appropriate for age and breed size
• Avoid excessive exercise in growing puppies
• Seek early treatment for joint injuries
• Attend routine veterinary check-ups
• Monitor for subtle changes in movement as your dog gets older

Prevention also includes paying attention to your dog’s overall health. Routine parasite control, for example, helps support general wellbeing and activity levels. If needed, you can explore our dog flea and worming products as part of your pet’s wider preventive care plan.

Living well with an arthritic dog

Many dogs with osteoarthritis continue to enjoy life for years with the right care. The key is recognising the signs early, staying in touch with your veterinary team and reviewing treatment as your dog’s needs change.

Arthritis management is often ongoing, and what works well at one stage may need adjusting later. Regular check-ups can help make sure your dog remains as comfortable and mobile as possible.

If your dog has been prescribed long-term medication, we can help make the process straightforward through our online pet pharmacy. You can also learn more about us, review our postage and delivery information, or contact us if you need help with an order.
