Hip dysplasia in dogs


  • Hip dysplasia is a condition in which the hip joint doesn’t fit together properly.
  • The bones inside the joint rub, causing swelling, pain and eventually arthritis.
  • Most dogs inherit hip dysplasia from one of their parents.
  • Symptoms often start at around 5-6 months old.
  • It most commonly affects medium - large breed pedigree dogs.
  • Management involves careful exercise, weight control and pain relief.
  • Severely affected dogs require surgery.
  • Schemes are in place to check for hip dysplasia before a dog has a litter of puppies. This reduces the number of puppies born with the painful condition.

What is hip dysplasia?

The hip is a 'ball and socket' joint which normally fits together perfectly. Hip dysplasia causes the hip joints to grow into an abnormal shape causing the bones to rub up against each other.

Hip dysplasia causes swelling, pain, stiffness and eventually arthritis.

Dogs with hip dysplasia usually start to show symptoms at around 5-6 months of age.

The condition tends to be worse in:

  • Medium - large breed dogs
  • Fast growing dogs
  • Overweight dogs (extra weight puts more strain on joints)
  • Dogs who have been over exercised when young.

Hip dysplasia causes the hip joint to grow into an abnormal shape.


  • Running with both back legs moving together - 'bunny hopping'
  • Limping
  • Stiffness
  • Difficulty getting up and lying down
  • A wobbly or swaying walk
  • Difficulty jumping or going up or down stairs
  • Less interest in walks
  • Skinny hips - a sign of small, weak muscles in the back legs and hips.

Some dogs with mild hip dysplasia won’t show signs until they are much older and they’ve developed arthritis.

Symptoms of hip dysplasia can be improved with:

Weight control

Anti-inflammatory pain relief

Controlled exercise

  • Unless your vet advises otherwise, regular, short lead walks are ideal.
  • Ensuring that your dog doesn't over-exercise is important. Avoid jumping, skidding, chasing, racing around, and walking or running for very long periods of time.


  • Periods of rest may be necessary when hip dysplasia is causing pain and discomfort.

Fortunately, dogs with mild hip dysplasia often improve a lot with the treatments above. If your dog responds well to this treatment it is likely your vet will advise you to continue caring for your dog at home without surgery.


  • If your dog has severe hip dysplasia that doesn’t respond to rest and medication your vet may suggest surgery.
  • There are a few different surgical options, your vet will help you select the best one for your dog. Most of the surgeries will mean that your dog will need to be referred to a specialist veterinary hospital.

Ongoing care

The symptoms of hip dysplasia usually continue throughout a dog’s life and they will often need additional ongoing care to control their pain. Your vet will be able to advise which of these options may be beneficial for your dog:


  • Physiotherapy can help build up muscle and take pressure off your dog’s hips.


  • Hydrotherapy is a great way to exercise your dog without putting strain on the joints.

Joint supplements


  • Acupuncture might help relieve pain caused by hip dysplasia.


Some dogs respond very well to treatment and their symptoms improve as they become an adult. Unfortunately, these dogs often still develop arthritis in their hips as they get older.

Some dogs don’t respond well to medical treatment and hip dysplasia continues to cause pain throughout their life. In these cases, stronger pain relief or surgery may be suggested.

If your dog’s pain becomes uncontrollable it may be necessary to consider making the very difficult decision to put them to sleep.

Preventing hip dysplasia 

The only way to prevent hip dysplasia is to avoid breeding from dogs with the condition. 

  • Always speak to your vet before choosing a new dog.
  • Take a look at PDSA’s PetWise quiz to help make sure you pick the most suitable pet for your lifestyle. If you choose to buy a pedigree breed ask the breeder about the parents' hip scores
  • There are lots of lovely, deserving dogs in rescue centres across the UK. You may be able to find the perfect pal in a 'breed specific rescue centre'. Please consider giving a rescue dog their forever home.
  • Always speak to your vet before considering breeding from your dog.

If your puppy is at risk of hip dysplasia or already has the condition:

  • Speak to your vet about how much exercise your puppy needs to ensure they receive the correct amount of exercise when they are young. It’s important to keep them fit but too much or the wrong type of exercise can make hip dysplasia worse. 
  • Ensure they are fed appropriate food for their size, breed and age. Your dog is more likely to have problems later in life if they don't have the correct nutrition as a puppy. Contact your vet practice for more information. 

When to contact your vet

Contact your vet if your dog is showing any of the symptoms listed above or you are worried about hip dysplasia.

You know your dog best. If they don’t have the symptoms listed above but you are still concerned it’s always best to contact your vet.

Before you consider breeding from your dog speak to your vet about screening for hip dysplasia and other inherited diseases.

Breeds at risk

Any breed of dog can develop hip dysplasia but it is much more common in medium to large breed pedigrees including:

  • Labrador
  • German Shepherd
  • Golden Retriever
  • Rottweiler
  • Bernese Mountain Dog
  • Newfoundland.

Certain breeds are more likely to get hip dysplasia.


Treatment for hip dysplasia can mount up to thousands of pounds over a dog’s lifetime. Think about insuring your dog as soon as you get them, before any signs of illness start. This means you will have all the support you need to care for them if they become poorly or develop a condition such as hip dysplasia.

It’s also very important to speak openly to your vet about your finances, the cost of treatment, as well as what you think is right for your dog. There are often several treatment options so if one doesn’t work for you and your pet then your vet may be able to offer another.
