Hip issues in dogs can cause stiffness, limping, difficulty getting up, reduced activity and changes in the way a dog walks or runs. Common causes include hip dysplasia, osteoarthritis and injuries affecting the hip and surrounding tissues.

However, a dog that appears to have painful or weak hips does not necessarily have a problem originating in the hip joint. Knee injuries, spinal conditions, muscle problems and neurological disease can produce similar changes in movement.

This is why persistent changes in your dog's gait should be assessed by a vet rather than diagnosed at home. Understanding how hip problems develop and recognising the early signs can still help you know when something needs attention.

What Are the Most Common Hip Problems in Dogs?

The two conditions owners are most likely to encounter when researching hip problems are canine hip dysplasia and osteoarthritis.

Hip dysplasia is a developmental condition involving abnormal development and instability of the hip joint. Osteoarthritis is a progressive joint disease involving changes to cartilage, bone and other structures within the joint. Hip dysplasia is one important cause of osteoarthritis, but arthritis can also develop following trauma and other joint abnormalities.

Dogs can also experience fractures, dislocations, muscle and tendon injuries, and other orthopaedic conditions affecting the hip region.

How Does a Dog's Hip Joint Work?

The hip is known as a ball-and-socket joint. The rounded head of the femur, the large bone of the upper hind leg, sits within a socket in the pelvis called the acetabulum.

In a healthy hip, these structures fit closely together while smooth articular cartilage covers the surfaces where the bones meet. The joint contains synovial fluid, which contributes to lubrication, while the joint capsule, ligaments and surrounding muscles help provide stability.

The hip must combine stability with a considerable range of movement. When the joint becomes unstable, damaged or arthritic, this carefully coordinated system can be disrupted. For a more detailed explanation of cartilage, synovial fluid and joint anatomy, read our guide to how dog joints work.

What Is Hip Dysplasia in Dogs?

Canine hip dysplasia is a developmental orthopaedic condition characterised by abnormal laxity or looseness within the hip joint. Instead of the ball and socket developing and functioning with normal stability, excessive movement can occur within the joint.

This abnormal mechanical environment can progressively damage joint tissues and contribute to the development of osteoarthritis.

According to the Cornell University College of Veterinary Medicine guide to canine hip dysplasia, the condition has an important genetic component, while environmental influences including nutrition and growth rate can affect its expression.

Which Dogs Are Most at Risk of Hip Dysplasia?

Hip dysplasia is particularly associated with medium, large and giant breeds, although smaller dogs can also be affected.

Breeds frequently associated with hip dysplasia include German Shepherds, Labrador Retrievers, Golden Retrievers, Rottweilers and other larger dogs.

Genetics are particularly important. This is why responsible breeding programmes use hip assessment schemes to reduce the likelihood of breeding from dogs with poor hip conformation.

Growth and nutrition also matter. Overfeeding a genetically susceptible growing puppy can promote excessive or rapid growth, potentially increasing expression of developmental orthopaedic disease. Large-breed puppies should therefore receive a nutritionally complete diet designed for appropriate controlled growth rather than being encouraged to grow as rapidly as possible.

Does Hip Dysplasia Always Cause Symptoms?

No. One of the complications of hip dysplasia is that the appearance of a dog's hips on radiographs and the severity of their outward symptoms do not always match closely.

Some dogs with substantial radiographic changes can remain surprisingly active, while others experience significant discomfort and impaired mobility.

Signs may appear in a young dog because of hip instability, or become more apparent later when secondary osteoarthritis develops.

What Is Osteoarthritis of the Hip?

Osteoarthritis is a progressive disease involving the whole joint. Although people often describe it simply as cartilage wearing away, the process is more complex and can involve cartilage deterioration, changes in the underlying bone, inflammation within the joint and alterations to surrounding tissues.

Hip dysplasia is one possible starting point. When an unstable hip moves abnormally over many years, repeated abnormal forces can contribute to progressive degenerative changes.

Previous trauma and other abnormalities of the hip can also eventually result in osteoarthritis.

Arthritis cannot simply be reversed by providing a particular food or supplement. Management instead aims to reduce pain, maintain function, preserve muscle and help the dog remain comfortably active.

What Are the Signs of Hip Problems in Dogs?

Signs of hip problems can include stiffness after rest, difficulty standing, limping, reduced willingness to exercise, difficulty climbing stairs and an unusual gait.

Changes are not always dramatic. Owners sometimes notice that their dog has gradually stopped doing things they previously enjoyed rather than developing an obvious limp.

Signs worth watching for include:

• Stiffness after sleeping or resting
• Difficulty rising from the floor
• Limping on a hind leg
• A swaying movement through the hips
• A bunny-hopping action when running
• Reluctance to jump into a car or onto furniture
• Hesitation when climbing stairs
• Shorter or slower walks
• Reduced interest in running or playing
• Loss of muscle around the hindquarters
• Shifting more weight towards the front legs
• Behavioural changes associated with discomfort

None of these signs proves that the hip is responsible. They tell you that your dog's movement has changed and that the cause may need investigating.

If your dog remains bright and happy despite an altered gait, our guide explaining why a dog may limp but otherwise act normally covers some of the other possible causes.

Could My Dog's Back Leg Problem Be Something Other Than Their Hip?

Yes. This is an important distinction because owners often describe any hind-limb stiffness or weakness as a problem with the hips.

The actual source could be elsewhere.

Possible causes include:

• Cruciate ligament disease affecting the knee
• Patellar luxation involving the kneecap
• Muscle or tendon injuries
• Paw or nail injuries
• Fractures or other trauma
• Spinal disease
• Neurological conditions
• Osteoarthritis affecting another joint

A dog struggling to stand may therefore have painful hips, but the same observation can occur with several very different conditions. This is one reason veterinary examination is more useful than trying to identify the problem from gait alone.

How Do Vets Diagnose Hip Problems in Dogs?

Diagnosis usually starts with a clinical history and physical examination. Your vet may ask when you first noticed the problem, whether it is worse after exercise or rest, whether an injury occurred and how the condition has changed.

The examination may include watching your dog walk and trot, assessing muscle mass, checking the range of movement in different joints and determining where pain appears to originate.

If hip dysplasia or osteoarthritis is suspected, radiographs are commonly used to assess the structure of the hip and look for abnormalities and degenerative changes. Correct positioning is important and sedation or anaesthesia may be needed to obtain suitable diagnostic images. Further investigations may be required when symptoms do not fit a straightforward hip problem.

How Are Hip Problems in Dogs Treated?

Treatment depends on what is actually wrong with the hip, the dog's age, the severity of the problem and how much it is affecting everyday life.

There is no single treatment plan appropriate for every dog with hip disease.

Weight Management

Maintaining an appropriate body condition is one of the most important modifiable factors in dogs with joint problems.

Additional body weight means additional mechanical load must be carried through the joints during standing, walking and running. Weight management is therefore particularly important in dogs already experiencing osteoarthritis or abnormal hip mechanics.

If your dog is overweight, speak to your veterinary practice about an appropriate calorie-controlled weight reduction programme rather than dramatically restricting food without nutritional guidance.

Controlled Exercise

Dogs with hip problems are not necessarily better off being completely inactive. Appropriate movement helps maintain muscle mass, cardiovascular fitness and joint function.

The type and amount of exercise should match the individual dog. Regular controlled walks may be more appropriate than occasional long walks, repetitive ball chasing or sudden bursts of strenuous activity.

A dog with significant disease may benefit from an individual exercise and rehabilitation programme developed with a vet or qualified veterinary physiotherapist.

Pain Relief and Medication

Dogs experiencing painful osteoarthritis may require veterinary medication. Non-steroidal anti-inflammatory drugs are commonly used in canine osteoarthritis, although suitability depends on the individual dog's health and other medications.

Never give human painkillers to a dog unless specifically instructed by a vet. Some common human medicines can be dangerous or potentially fatal to dogs.

Physiotherapy and Rehabilitation

Veterinary rehabilitation can form part of a multimodal treatment plan. The objective may include maintaining muscle strength, improving controlled movement and preserving useful range of motion.

Hydrotherapy may be suitable for some dogs, but it is not automatically appropriate for every hip condition. Rehabilitation should be tailored to the diagnosis rather than started simply because a dog appears stiff.

Can Dogs Need Hip Surgery?

Yes. Some dogs with severe hip dysplasia or other significant hip disease may be candidates for surgery.

The procedure depends heavily on age and the nature of the problem. In young dogs diagnosed sufficiently early, certain procedures aim to alter hip development before advanced degenerative changes occur. Other dogs with severe disease may be considered for procedures including femoral head and neck excision or total hip replacement.

Many dogs with hip dysplasia do not require surgery, but early diagnosis matters because some surgical options are only available during particular stages of growth.

Can Joint Supplements Help Dogs With Hip Problems?

Joint supplements are commonly used as part of a wider mobility programme, but they should not be confused with treatment for structural hip disease.

A nutritional supplement cannot tighten a dysplastic hip, restore normal hip anatomy or replace pain relief required by a dog experiencing significant osteoarthritis.

Ingredients used in canine joint formulations include omega-3 fatty acids, glucosamine, chondroitin, collagen, green-lipped mussel and hyaluronic acid. The quality and strength of clinical evidence varies between ingredients and products.

It is therefore more appropriate to consider nutritional joint support as one possible component of a wider plan involving healthy body condition, appropriate exercise, veterinary treatment where required and a nutritionally complete diet.

What Can I Do at Home to Help a Dog With Hip Problems?

Small environmental changes can make everyday activities easier for a dog with reduced mobility.

• Place rugs or non-slip runners over slippery flooring.
• Provide a supportive bed in an easily accessible location.
• Keep nails appropriately trimmed to improve foot placement and grip.
• Avoid sudden increases in exercise.
• Maintain a lean, healthy body condition.
• Use a suitable ramp where getting into a vehicle has become difficult.
• Monitor how your dog moves after rest and exercise.
• Follow medication and rehabilitation instructions consistently.

Our guide to making the home more comfortable for dogs with arthritis contains further practical changes for dogs experiencing reduced mobility.

Diet also matters, particularly because calorie intake affects body condition. Our guide to the best foods for dogs with joint problems explains how nutrition can fit into a broader joint-care plan.

When Is a Dog's Hip Problem an Emergency?

Gradual stiffness generally warrants a normal veterinary appointment, but sudden or severe symptoms can require more urgent assessment.

Contact a vet promptly if your dog:

• Suddenly cannot stand or walk normally
• Cannot put weight through a hind leg
• Develops severe or rapidly worsening pain
• Has suffered significant trauma such as a road accident or fall
• Develops sudden weakness or loss of coordination in the hind legs
• Cries out repeatedly when moving or being touched
• Develops paralysis or drags one or both hind limbs

Sudden hind-limb weakness is particularly important because the problem may originate from the nervous system or spine rather than the hips.

A Practical Hip and Mobility Care Checklist

Frequently Asked Questions About Hip Issues in Dogs

How Can I Tell if My Dog Has Hip Problems?

Possible signs include stiffness after rest, difficulty standing, hind-leg lameness, reluctance to jump or climb stairs, a swaying gait and reduced enthusiasm for exercise. These symptoms can also occur with knee, spinal and muscular conditions, so diagnosis requires veterinary assessment.

What Does a Dog With Hip Dysplasia Walk Like?

Some dogs develop a swaying gait or use both hind legs together in a movement often described as bunny hopping. Others simply appear stiff or intermittently lame. Gait alone cannot confirm hip dysplasia.

At What Age Does Hip Dysplasia Show in Dogs?

Signs can occur while a dog is still young, particularly when significant joint laxity is present. Other dogs may show few obvious symptoms until osteoarthritis develops later in life. The age at which symptoms become noticeable therefore varies considerably.

Can Hip Dysplasia Be Cured?

Hip dysplasia is a structural developmental condition rather than a temporary illness. Management depends on severity. Some dogs remain comfortable with weight management, appropriate exercise, rehabilitation and veterinary medication, while selected dogs may benefit from surgery.

Should You Walk a Dog With Hip Problems?

Many dogs with hip disease benefit from appropriate controlled activity rather than complete inactivity. However, the amount and type of exercise should reflect the dog's diagnosis, pain level and fitness. Ask your vet or veterinary physiotherapist for individual guidance if your dog has significant disease.

Can Hip Dysplasia Suddenly Appear in an Older Dog?

Hip dysplasia develops while the dog is growing, so an older dog does not suddenly develop the underlying developmental abnormality. However, symptoms can become noticeable later as secondary osteoarthritis progresses. Sudden lameness in an older dog should still be investigated because another injury or condition may be responsible.

Can a Dog Live a Normal Life With Hip Dysplasia?

Many dogs with hip dysplasia maintain a good quality of life, particularly when the condition is recognised and appropriately managed. The outlook depends on the severity of joint abnormalities, osteoarthritis, body condition, age and response to treatment.

The Bottom Line

Hip issues in dogs range from developmental conditions such as hip dysplasia to osteoarthritis, trauma and other orthopaedic problems. Stiffness, limping and difficulty getting up are useful warning signs, but they cannot identify the underlying cause by themselves.

The most effective approach begins with an accurate diagnosis. Maintaining a healthy body condition, providing appropriate exercise, making practical changes at home and following veterinary treatment can then help many dogs remain active and comfortable.

Most importantly, do not assume that stiffness or slower movement is simply an inevitable part of getting older. Persistent changes in mobility deserve investigation, while sudden severe pain, weakness or inability to walk requires prompt veterinary attention.
