Dog Arthritis: Symptoms and Long-Term Treatment

Arthritis is one of the most common long-term conditions seen in dogs, especially as they get older. It can affect mobility, comfort and overall quality of life, but with the right support many dogs can continue to enjoy happy, active lives for years.

For many owners, the first signs are easy to miss. A dog with arthritis may simply seem to be slowing down, becoming less playful or taking a little longer to get up after a nap. Recognising these early changes can make a real difference, as prompt veterinary advice and long-term management can help keep pain under control and support your dog’s joints.

At Vetscriptions, we help UK pet owners access genuine pet medicines, supplements and healthcare products in a simple and affordable way. This article explains the common symptoms of dog arthritis, how it is diagnosed, and the treatment and mobility support options that may help.

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 arthritis in dogs?

Arthritis, often called osteoarthritis, is a painful condition that affects the joints. It happens when the smooth surfaces within a joint begin to wear down, leading to inflammation, stiffness and discomfort. Over time, this can make movement more difficult and painful.

Arthritis can affect any joint, but it is often seen in the hips, elbows, knees, shoulders and spine. It is more common in older dogs, but younger dogs can develop it too, especially if they have had a joint injury or have an underlying orthopaedic problem such as hip dysplasia or elbow dysplasia.

What causes arthritis in dogs?

There is not always one single cause. In many dogs, arthritis develops gradually over time as joints age and experience wear and tear. In others, there may be a contributing problem that damages the joint earlier in life.

• Age-related joint wear and tear
• Previous injuries to a joint
• Hip dysplasia or elbow dysplasia
• Cruciate ligament disease
• Obesity, which puts extra strain on joints
• Joint instability or abnormal joint development

Large breed dogs are often more prone to joint problems, but arthritis can affect dogs of any size or breed.

Common symptoms of arthritis in dogs

Arthritis symptoms can come on gradually, so they are sometimes mistaken for normal ageing. However, ongoing stiffness or reluctance to move should not be ignored. Dogs are often very good at hiding pain, which means the signs can be quite subtle at first.

Signs to look out for

• Stiffness, especially after rest or first thing in the morning
• Limping or favouring one leg
• Slowing down on walks
• Reluctance to jump into the car or onto furniture
• Difficulty climbing stairs
• Finding it hard to stand up or lie down
• Less interest in play or exercise
• Changes in behaviour, such as grumpiness or seeming withdrawn
• Licking at joints or sensitive areas
• Muscle loss, especially around the back legs

Some dogs may also sleep more, seem less enthusiastic about daily routines or become unsettled at night because they are uncomfortable.

When to contact your veterinary surgeon

If you notice any of the signs above, it is a good idea to book an appointment with your veterinary surgeon. Early assessment is important, because stiffness and limping are not always caused by arthritis. Other conditions, including injuries, spinal problems or more serious illnesses, may need to be ruled out.

You should seek veterinary advice promptly if your dog:

• Has sudden or severe lameness
• Cries out in pain
• Stops bearing weight on a leg
• Seems distressed, lethargic or generally unwell
• Has a rapid change in mobility

How arthritis is diagnosed

Your veterinary surgeon will usually start by asking about your dog’s symptoms, daily routine and medical history. They will examine your dog’s gait, joints and muscles, checking for stiffness, pain, swelling or reduced range of movement.

In some cases, X-rays may be recommended to assess the joints and look for signs of wear and tear. Sometimes further tests are needed depending on your dog’s age, symptoms and overall health.

A proper diagnosis is important because it helps make sure your dog receives the most suitable treatment plan.

Long-term treatment options for dog arthritis

Arthritis is usually managed rather than cured, which means treatment focuses on reducing pain, improving mobility and helping your dog stay comfortable over time. Many dogs benefit from a combination of approaches rather than one single treatment.

Prescription pain relief and anti-inflammatory medication

Prescription medication is often a key part of arthritis management. Anti-inflammatory medicines can help reduce joint inflammation and relieve pain, making it easier for dogs to move comfortably. Other pain relief options may also be recommended depending on your dog’s individual needs.

These medicines should only be given under veterinary guidance. Human painkillers can be extremely dangerous to dogs, so never give your pet medication intended for people unless your vet has specifically advised it.

If your dog has been prescribed treatment, you can browse dog prescription products through Vetscriptions. If you are unsure about the process, our guide on how to order a prescription medicine and our prescription FAQs may also be helpful.

Joint supplements

Some dogs may benefit from joint supplements as part of their long-term care plan. These are often used to support joint health and mobility alongside other treatments, rather than replacing prescribed medication when pain relief is needed.

Ingredients commonly included in joint supplements may include glucosamine, chondroitin, green lipped mussel, omega-3 fatty acids and other nutrients that support joint function. Results can vary between dogs, so it is worth asking your veterinary surgeon what may be most suitable.

We stock a range of dog joint care products, as well as our own brand premium supplements, which may be useful for dogs needing ongoing joint support.

Weight management

Keeping your dog at a healthy weight is one of the most important parts of arthritis care. Extra body weight puts added pressure on already sore joints, which can make symptoms worse.

If your dog is overweight, even a small reduction in weight can make a meaningful difference to comfort and mobility. Your veterinary surgeon can advise on a safe weight-loss plan and whether a specific diet would be helpful. Choosing appropriate nutrition from our dog food and treats range may also support overall health as part of a vet-guided plan.

Controlled exercise

Regular, gentle exercise helps maintain muscle strength and joint movement. Complete rest is not usually recommended for arthritis unless your vet advises it for another reason.

Helpful approaches often include:

• Short, steady walks rather than occasional long walks
• Low-impact activity on non-slip surfaces
• A consistent daily routine
• Avoiding sudden bursts of high-impact exercise if painful

Some dogs also benefit from hydrotherapy or physiotherapy, which your veterinary surgeon may recommend.

Home and mobility support

Simple changes at home can make day-to-day life more comfortable for an arthritic dog.

• Use non-slip rugs or mats on slippery floors
• Provide a warm, supportive bed in a draught-free area
• Consider ramps for cars or steps to reduce jumping
• Keep food, water and sleeping areas easy to access
• Dry your dog well after wet walks to help keep joints warm

Supportive items from our dog accessories collection may help improve comfort at home, particularly for dogs who struggle with stairs, jumping or getting settled.

Monitoring your dog over time

Arthritis often changes gradually, so regular check-ins with your veterinary surgeon are important. Your dog’s treatment may need adjusting over time as symptoms progress or as their needs change.

It can help to keep a simple diary of:

• How easily your dog gets up and lies down
• How far they are comfortable walking
• Any limping or stiffness
• Changes in behaviour or sleep
• How well medication seems to be working

This information can make it easier for your vet to assess whether your dog’s arthritis is stable or whether treatment needs to be reviewed.

Can arthritis be prevented?

Arthritis cannot always be prevented, but some steps may reduce the risk or help delay its progression. These include maintaining a healthy weight, feeding a balanced diet, providing suitable exercise and addressing joint injuries or developmental problems early.

For dogs already showing stiffness or reduced mobility, early treatment is often the best way to help preserve quality of life for as long as possible.

Supporting your dog with confidence

Living with arthritis does not mean your dog cannot still enjoy life. With careful monitoring, veterinary support and the right combination of medication, supplements and practical changes at home, many arthritic dogs remain bright, comfortable and engaged in family life.

If your dog is showing signs of joint pain or stiffness, speak to your veterinary surgeon for advice on diagnosis and treatment. If you already have a prescription in place, we can help you order genuine medication responsibly through our dog collection and wider prescription medicines range.
