Elbow dysplasia in dogs is a common joint condition that affects many dogs, particularly larger breeds. It occurs when the bones in the elbow joint don't fit together properly, leading to pain and mobility issues.

The bones in a dog's front legs are called the humerus, the radius and the ulna. The humerus sits between a dog's shoulder and their elbow. The radius and ulna sit below their elbow and carpus joints (equivalent to our wrist).

Elbow dysplasia in dogs occurs when there's abnormal development of the elbow joint, and therefore it's generally seen in young dogs.

What Does Elbow Dysplasia Look Like in Dogs?

There are different types of elbow dysplasia in dogs, and treatment depends on the specific type and its severity. The most common types include:

• Fragmented medial coronoid process: This occurs when the coronoid process, a bony triangular structure part of the ulna, fractures due to abnormal joint movement and stress, leading to pain and discomfort.
• Ununited anconeal process of the ulna: In this type, a bone fragment called the anconeal process fails to fuse properly with the ulna, causing pain and hindering normal joint function.
• Osteochondritis (osteochondrosis of the medial humeral condyle): This occurs when cartilage separates from the bone at the end of the humerus, resulting in inflammation, joint instability, and pain.

Treatment for these conditions can range from conservative management to surgical intervention, depending on the type and severity of the dysplasia.

What are the Signs of Elbow Dysplasia in Dogs?

Dogs affected by elbow dysplasia typically show symptoms from a young age, usually between 5 and 18 months. You might notice your dog limping or 'bobbing' its head to one side as it walks. They may appear stiff when getting up or be reluctant to play.

Some dogs may sit with their elbows pointed outward rather than held against their body. In time, they may even walk with their front legs turned outwards, which can affect their overall gait, movement and range of motion.

What Causes Elbow Dysplasia in Dogs?

Elbow dysplasia is a genetic condition that should be screened for before breeding to prevent passing the condition to future generations.

Large and giant breed dogs are most commonly affected, often due to their rapid growth and heavier body weight, which puts extra stress on their joints. Young dogs, especially those that grow too quickly, and overweight dogs are also at an increased risk.

Which Dogs are Most Likely to Develop this Condition?

These dog breeds are more predisposed to developing canine elbow dysplasia due to their size and genetic factors:

• German Shepherds
• Mastiffs
• Labrador Retrievers
• Golden Retrievers
• Rottweilers
• Basset Hounds
• Newfoundlands
• Bernese Mountain Dogs

How to Diagnose Elbow Dysplasia in Dogs

Your vet will start with a thorough clinical examination, checking your dog's overall health and manipulating their joints to check for pain, stiffness, or discomfort.

X-rays are usually necessary to diagnose a dog with elbow dysplasia, as they provide a clear image of the joint's structure. Sometimes, additional imaging like a CT scan or MRI might be recommended to get a more detailed view of the joint and assess any damage more precisely.

Your vet will discuss the typical symptoms of elbow dysplasia in dogs with you and may ask you to keep a record of any lameness, changes in movement, or difficulty with daily activities.

What is the Treatment for Elbow Dysplasia in Dogs?

Elbow dysplasia in dogs' treatment varies depending on the severity of the condition in affected dogs. In mild cases, management may include weight control, controlled exercise, and medication, like anti-inflammatories or platelet-rich plasma, which help with pain and inflammation. Physical therapy and hydrotherapy can also help. 

Surgery for Elbow Dysplasia in Dogs

In severe cases, surgical treatment may be required. Veterinary surgeons have different surgical techniques depending on the damage caused to the joint from elbow dysplasia. For example, a fragmented medial coronoid process may require surgery called arthrotomy to remove the broken bone fragments.

For osteochondrosis, treatment of the medial humeral condyle could involve removal of the separated cartilage.

Another treatment option is an ulnar osteotomy. Your veterinary surgeon will be best to advise you on the most suitable surgery or treatment for your pet.

Can Elbow Dysplasia in Dogs be Cured?

Surgery can provide a long-term solution, but it's not a cure. Many dogs suffering from elbow dysplasia will also develop arthritis and experience ongoing joint damage, which will require continued management.

While elbow dysplasia is a lifelong condition, it doesn't impact a dog's life expectancy. With the right care, dogs with elbow dysplasia can live happy, active, and fulfilled lives.

For affected dogs, providing a comfortable, supportive bed is essential. You may also want to consider using ramps or steps to help your dog access furniture or get into the car without putting strain on their joints.

Exercise should be moderate to avoid overloading the joints. Swimming and hydrotherapy can be excellent forms of low-impact exercise that offer both physical activity and mental enrichment. Your vet can guide you in choosing joint supplements and effective pain management options to support your dog's quality of life.

How to Prevent Elbow Dysplasia in Dogs?

To help prevent and manage elbow dysplasia in dogs, they should be checked and have their elbows screened before breeding.

If you're buying a puppy from one of the at-risk breeds, check with the breeder that the parents were screened before breeding. If a dog shows any signs of elbow dysplasia, they should not be used for breeding, as it's likely that their offspring will also suffer from the condition, which affects a dog's quality of life.

Although many cases of elbow dysplasia cannot be prevented, managing their exercise while young will prevent the condition from rapidly becoming worse.

Dogs at risk of elbow dysplasia shouldn't be allowed to exercise in excess. Large breed puppies that are rapidly growing can be helped by having a good quality diet with joint supplements. Discuss suitable diets and an exercise plan for large breed puppies with your vet.

Does Elbow Dysplasia in Dogs Come and Go?

Elbow dysplasia is a common condition in dogs, but each case is unique. The dog's response to treatment will vary depending on the severity of the disease, their overall health, and their stage of growth.

Working closely with your vet is essential to developing the most effective treatment plan tailored to your pet's specific needs. While elbow dysplasia is a lifelong condition, there are numerous management options available, including medication, exercise adjustments, and possibly surgery.

With the right care and lifestyle changes, many dogs with elbow dysplasia can live a long, active, and fulfilling life.
