Arthritis in dogs can cause limping, stiffness and changes in everyday behaviour. In a young dog, joint problems may be linked to abnormal development or an earlier injury. If your puppy or young dog is moving differently, arrange a veterinary check rather than assuming it is a normal part of growing up.
Understanding canine arthritis
Arthritis means inflammation of a joint. Osteoarthritis is the progressive joint disease often associated with it, causing discomfort and changes in movement. It can affect more than one joint.1
Joint pain secondary to arthritis in dogs is highly variable. A dog's X-rays are only part of the picture: your vet will also assess how they move, examine their joints and ask about changes you have noticed. Arthritis is often associated with larger dogs, but small dogs can develop painful joint problems as well.3
Luxating patellas, or slipping kneecaps, can cause limping, skipping or bunny-hopping in the hind limbs and may contribute to arthritis. Painful joints can also make a dog less willing to exercise or more sensitive to being touched. Changes such as irritability or withdrawing from play are worth mentioning to your vet.2
What can cause arthritis in young dogs?
A common underlying problem is joint dysplasia. Dysplasia means abnormal development: the joint does not form or fit together normally, which can increase the risk of arthritis. Hip and elbow dysplasia are important causes of pain and lameness in young, particularly large-breed, dogs.2
Hip and elbow dysplasia have an inherited component, with growth and other factors also influencing how the condition develops. Appropriate nutrition and an exercise plan suited to a growing dog are important. Ask your vet about suitable food and activity rather than trying to accelerate growth or adding extra nutrients yourself.
Hip dysplasia affects the back legs. It involves a loose or poorly fitting hip joint and may cause difficulty rising, reduced interest in jumping or loss of muscle around the hindquarters. A young dog can have painful hip dysplasia before established arthritis is visible.3
Elbow dysplasia affects the front legs. The term describes several developmental problems in the elbow, which can occur alone or together. It may affect both elbows, so a change in gait is not always an obvious one-sided limp.5
Joint injuries and other developmental abnormalities can also contribute to early arthritis. Your vet will investigate the cause because limping in a young dog can have many explanations, including problems that need a different treatment.
Alongside your vet's care plan, you can explore our pet joint supplements and discuss which, if any, suit your dog's age, diet and individual needs.

Arthritis in dogs: symptoms to look out for
Look out for changes in your dog's behaviour or everyday routines: are they doing anything differently, has their movement changed, or do they seem less interested in affection or games? These signs can occur with arthritis, but do not confirm a diagnosis on their own.
| Possible sign | What you may notice | What to do |
|---|---|---|
| Limping or a changed gait | Favouring a leg, skipping or moving stiffly | Arrange a vet check, even if it comes and goes. |
| Stiffness after resting | Taking longer to get up or moving cautiously at first | Note when it happens and tell your vet. |
| Reluctance to exercise or jump | Less interest in games, stairs or getting into the car | Discuss changes in activity rather than pushing through them. |
| Licking or sensitivity | Repeatedly licking a joint or reacting when touched | Ask your vet to check for pain, injury or a skin problem. |
| Muscle or behaviour changes | A narrower hind end, sleeping more or becoming withdrawn or irritable | Report the change as part of your dog's overall assessment. |
| Severe pain or inability to bear weight | Not putting a leg down or being suddenly very distressed | Contact your vet immediately. |

My young dog has arthritis. What next?
Early assessment helps your vet identify the underlying problem and plan care. Treatment may include veterinary pain relief, weight management, changes to exercise and rehabilitation. Surgery is considered in selected cases, depending on the joint problem, age and severity; it is not automatically required for every young dog with arthritis.
Arrange follow-up appointments so the plan can be adjusted as your dog grows or their symptoms change. Give medicines exactly as prescribed, and never give human painkillers unless your vet has specifically instructed you to do so.1
Manage their weight
One of the most important ways to care for a young dog with arthritis is to maintain a healthy body condition. Excess weight adds strain to joints and can make movement harder. For a growing dog, your vet can help you balance joint care with their nutritional needs.
Use body shape as well as the scales: you should generally be able to feel the ribs with light pressure and see a waist from above. Coat, breed and build can make this harder to judge, so ask your veterinary team to show you how to assess your own dog.7
Choose the right bed and home setup
Dogs with painful joints benefit from a comfortable, supportive sleeping surface. Choose a bed that is easy to step onto and large enough to stretch out on. A well-supported foam bed may be useful, but comfort and easy access matter more than one particular filling.
Rugs or non-slip mats can make smooth floors easier to walk on. A suitable ramp may also help with access to the car or other raised areas, reducing the need to jump.1
Maintain muscle mass with suitable exercise
It is important for young dogs with arthritis to maintain healthy muscle mass. Muscle helps support joints, but repeated jumping, sudden turns and high-impact activity may be uncomfortable. Ask your vet to recommend the length and type of walks for your dog.6
Veterinary physiotherapy and supervised hydrotherapy may be helpful. Swimming or an underwater treadmill can provide exercise while water supports the body, but the programme needs to suit your dog's condition. Discuss a qualified rehabilitation service with your vet rather than assuming unrestricted swimming is appropriate.8
The importance of nutrition
Start with a complete food appropriate for your dog's life stage and size. A growing puppy's diet needs to support steady development, and portion sizes should be reviewed as they grow.
Joint supplements for dogs offer different formulations, including glucosamine, chondroitin and other ingredients. Compare the label and feeding guidance with your vet to choose an option that fits your dog's care plan. Supplements are an addition to suitable food and veterinary treatment, and your vet can help you monitor whether they are useful for your individual dog.6
Arthritis in young dogs FAQs
Can young dogs and puppies get arthritis?
Yes. Arthritis is more common as dogs get older, but joint disease can begin during growth. Developmental problems such as hip or elbow dysplasia, or joint injuries, can increase the risk. Persistent limping in a puppy deserves a vet check.
What age do dogs get arthritis?
There is no single starting age. Risk increases with age, but an underlying joint problem may cause symptoms in a young dog. For example, elbow dysplasia can cause lameness from around five months; those signs do not by themselves prove arthritis is already present.5
How do I know if my dog has arthritis?
Watch for stiffness, limping, reduced interest in walks or games, and changes in behaviour. A vet will assess the joints and movement and may recommend imaging. Keep notes of when the signs appear, as other conditions can look similar.
Can arthritis affect a dog's front legs, back legs or paws?
Yes. Different joints can be affected, including elbows in the front legs, hips or knees in the back legs, and joints in the toes. Paw licking or a limp can also come from a claw injury, a foreign body or another problem, so the location needs a veterinary assessment.
Are Labradors more likely to develop arthritis?
Labradors are among the breeds predisposed to hip and elbow problems that can lead to arthritis. Breed is only part of the picture: body condition, joint development and previous injuries also matter. Mention changes in movement even if your Labrador is still young.6
Should I still walk my dog if they have arthritis?
Usually, an individually planned exercise routine is useful for maintaining movement and muscle. Your vet can advise on shorter, regular walks and suitable surfaces. If your dog develops a new limp or cannot bear weight, seek advice before continuing the usual routine.
How can I help my dog with arthritis at home?
Focus on comfortable bedding, good grip on floors, a healthy body condition and the exercise your vet recommends. Keep a simple record of mobility, enthusiasm and comfort so you can discuss progress at reviews. You can also ask about suitable pet joint supplements.
Can arthritis in young dogs be cured?
Established osteoarthritis cannot usually be reversed, but a tailored plan can improve comfort and quality of life. Some underlying developmental problems have treatment options, including surgery in selected cases. Early assessment helps your vet choose the right approach.
