Arthritis in Dogs and Cats: Signs, Treatment, and Management

Watching your pet struggle to get up, hesitate before jumping, or lose interest in walks can be worrying. Many pet parents assume these changes are simply part of getting older, but they often point to another painful issue rather than old age itself. Yes, we’re talking about arthritis. This common joint condition affects both dogs and cats and can gradually reduce their mobility and quality of life.

Fortunately, with early diagnosis and the right management, many pets with arthritis can continue to lead happy, active lives. In this informative guide, we’ve covered everything you need to know about arthritis in pets, from its causes and symptoms to diagnosis and treatment.

What is Arthritis in Pets?

Osteoarthritis, commonly called arthritis, is a chronic degenerative joint disease that affects the cartilage and other structures within the joints. As the protective cartilage gradually wears away, the bones begin to rub against each other, causing pain, inflammation, stiffness, and reduced mobility. It is a progressive condition, meaning it worsens over time if left unmanaged.

While the damage cannot be reversed, early diagnosis and appropriate treatment can help slow its progression, reduce discomfort, and improve your pet's quality of life. Although arthritis is most commonly associated with old age, it can develop in pets of any age. There are several factors that can contribute to the early onset of arthritis.

Common Causes of Arthritis in Pets

Arthritis isn’t just an old age problem in pets; it can develop because of several reasons. Let’s discuss some of these here:

Genetics

Unfortunately, some breeds are genetically predisposed to developing arthritis or joint issues. Due to their size and weight, certain dog breeds such as Labradors, Great Danes, German Shepherds, and Retrievers are at greater risk. Some of the cat breeds that are more prone to developing arthritis include Scottish Folds, Persians, Siamese, and Maine Coons.

Age

The most common cause of arthritis in pets is ageing. As pets grow older, the natural wear and tear on their joints causes the protective cartilage to gradually wear away, leading to inflammation, pain, stiffness, and reduced mobility.

Development issues

Some pets are born with or develop joint abnormalities during growth that increase their risk of arthritis later in life. Conditions such as hip dysplasia, elbow dysplasia, patellar luxation, and osteochondritis dissecans (OCD) can affect normal joint development. These conditions cause uneven wear on the joints, leading to chronic inflammation and the early onset of osteoarthritis.

Obesity

Obesity is becoming one of the leading contributors to joint problems in pets. Excess body weight places additional stress on the joints, particularly the hips, knees, and elbows. Over time, this increased pressure accelerates cartilage wear, raises the risk of arthritis, and can worsen existing joint pain.

Previous injury or trauma

Pets that have sustained an injury or had surgeries are also at a higher risk of developing osteoarthritis. This includes previous fractures, ligament injuries, muscle injuries, or joint infections. Such accidents or injuries can leave the joint unstable, which may lead to the development of arthritis later.

Symptoms of Arthritis in Dogs and Cats

The following are some of the most common signs that will help you recognise osteoarthritis in pets.

• Reduced activity
• Difficulty getting up and altered gait
• Limping or preferring one leg
• Slow walking or stiffness, especially after resting
• Swollen or enlarged joints
• Hiding or avoiding interaction
• Increased irritability
• A hunched posture or arched back
• Resistance to exercise or play
• Difficulty in using litter box
• Hesitation to jump

Spotting these signs early can help make a great difference in preserving your pet’s quality of life. So, if you notice these signs, promptly book an appointment with your veterinarian and take your pet for a check-up.

Diagnosis of Arthritis in Pets

When you are at the vet, they will start the diagnosis with a physical examination. The vet will do a thorough examination to assess your pet's symptoms, mobility, and level of pain. They will also enquire about the onset and severity of the symptoms and the medical history of your pet to ascertain the underlying cause.

To get a better picture (literally) of the condition, they will also recommend diagnostic imaging tests such as X-rays and CT scans. This helps evaluate the joint damage and rule out other possible conditions.

In some cases, the vet may employ a diagnostic tool called force plate analysis. This tool helps locate where the lameness is within the joint and understand its severity. In this test, the pet walks over a specially designed force plate, which measures the reaction forces exerted by a dog’s limbs. It can provide an insight into the pet’s gait, limb usage, and any abnormalities.

Treatment Options for Arthritis in Pets

Unfortunately, there’s no cure for arthritis. Therefore, treatment focuses on managing the condition, relieving pain, and slowing its progression to improve your pet’s quality of life. Depending on your pet’s age, overall health, and the severity of the arthritis, your veterinarian may recommend a combination of the following:

Weight management

Maintaining a healthy body weight is one of the most effective ways to reduce the strain on your pet's joints. Even modest weight loss can noticeably improve comfort and mobility. Your veterinarian can recommend a suitable weight management plan based on your pet's age, breed, and health condition.

Regular, controlled exercise

Low-impact activities such as short walks, swimming, or gentle play help maintain muscle strength, improve joint flexibility, and prevent stiffness. Avoid intense or high-impact exercise that may worsen joint damage.

Balanced diet

A nutritious, well-balanced diet supports overall health and helps maintain an ideal body weight. In some cases, your veterinarian may recommend a therapeutic diet specifically formulated to support joint and cartilage health.

Pain relievers

Your veterinarian may prescribe non-steroidal anti-inflammatory drugs (NSAIDs) or other pain-relieving medications depending on your pet's needs. Always use medications exactly as prescribed and never give human pain medicines to pets, as many can be toxic.

Nutritional supplements

Joint supplements containing ingredients like glucosamine, chondroitin sulphate, omega-3 fatty acids, or green-lipped mussel extract may help support cartilage health and reduce inflammation. They can be beneficial when used as part of a comprehensive treatment plan.

Physical therapies

Physical rehabilitation can help improve strength, flexibility, and mobility while reducing discomfort. Depending on your pet's needs, your veterinarian may recommend physiotherapy, hydrotherapy, massage, stretching exercises, laser therapy, or acupuncture.

Surgery

In severe cases where medical management is no longer effective, surgical options such as joint repair, joint replacement, or joint fusion may be considered. Your veterinarian or a veterinary orthopaedic specialist can determine whether surgery is appropriate for your pet.

Arthritis Management at Home

Along with veterinary treatment, making a few changes around your home can help keep your arthritic pet comfortable, improve their mobility, and make daily activities easier.

• Provide a soft, supportive bed to cushion painful joints and keep your pet comfortable while resting.
• Keep your pet warm, as cold weather can make joint stiffness worse. Place their bed away from cold areas and provide warm bedding during winter.
• Use non-slip mats or rugs on slippery floors to prevent falls and make walking easier.
• Install ramps or pet stairs to help your pet get onto beds, sofas, or into vehicles without jumping.
• Keep essentials within easy reach, including food, water, bedding, and litter trays, so your pet doesn't need to move a lot.
• Raise food and water bowls for larger dogs if bending becomes uncomfortable.
• Trim your pet's nails regularly to improve grip and reduce the risk of slipping.
• Provide gentle daily movement, but allow your pet to rest whenever needed. Avoid excessive exercise or rough play.
• Schedule regular veterinary check-ups so your pet's condition and treatment plan can be reviewed and adjusted as needed.

Parting Words

Living with arthritis can be challenging for pets, but your care and support can make a world of difference. If your pet has started slowing down or seems reluctant to jump, it's worth arranging a veterinary check-up sooner rather than later. With early intervention and right care, you can help reduce your pet's discomfort and improve their quality of life.
