Hip Dysplasia in Dogs: Signs, Causes, and Treatment Options

What Is Hip Dysplasia in Dogs?

Hip dysplasia is a common skeletal condition that develops during a dog’s growth stage. This progressive disorder occurs when the ball and socket of the hip joint don’t develop properly, resulting in joint laxity – meaning the hip joints are looser than they should be. As a puppy grows, this abnormal development causes the joint to deteriorate over time, leading to painful arthritis, decreased mobility, and reduced quality of life.

While hip dysplasia is often associated with large and giant breed dogs, it can affect canines of any size. The condition ranges from mild to severe, with symptoms that may appear as early as a few months of age or develop later in life.

Causes of Hip Dysplasia in Dogs

Hip dysplasia in dogs develops from a complex interplay of genetic and environmental factors. Understanding these causes can help pet parents take preventive measures where possible.

Genetic Factors

Hip dysplasia has a strong hereditary component, which is why responsible breeding practices are crucial for reducing its prevalence. Dogs with hip dysplasia should not be bred, as they can pass the genetic predisposition to their offspring. Certain breeds have higher rates of hip dysplasia due to their genetic makeup, including:

• German Shepherds
• Labrador Retrievers
• Golden Retrievers
• Rottweilers
• Saint Bernards
• Great Danes
• Bulldogs

Environmental Factors

Several environmental factors can influence the development and progression of hip dysplasia in genetically predisposed dogs:

• Rapid growth rate: Puppies that grow too quickly may develop skeletal abnormalities, including hip dysplasia.
• Improper nutrition: Diets too high in calories, calcium, or supplements can contribute to abnormal joint development.
• Excessive exercise: High-impact activities during a dog’s growth period may increase the risk of developing hip dysplasia.
• Obesity: Excess weight puts additional stress on joints, potentially exacerbating hip dysplasia.
• Inappropriate exercise: Certain activities that involve jumping or standing on hind legs can strain developing joints.

Signs and Symptoms of Hip Dysplasia

Hip dysplasia can manifest in various ways, and symptoms may appear at different life stages. Some dogs show signs as puppies, while others develop symptoms as they age and secondary arthritis sets in. Being aware of these signs can help with early detection and intervention.

Early Signs in Puppies (4-12 months)

• Difficulty rising from a sitting or lying position
• Reluctance to run, jump, or climb stairs
• Bunny-hopping gait when running
• Decreased activity level or interest in play
• Noticeable pain or discomfort when the hip area is touched
• Audible clicking sounds from the hip joint during movement

Signs in Adult Dogs

• Stiffness, especially after resting or in cold weather
• Limping or favoring one or both hind legs
• Muscle loss in the thigh area
• Visible enlargement of shoulder muscles as they compensate for hip weakness
• Swaying, “bunny hopping” gait
• Pain when hips are extended or manipulated
• Difficulty with certain movements like jumping into a car

Diagnosing Hip Dysplasia

If you notice any of the above symptoms in your dog, a veterinary evaluation is essential. The diagnostic process typically involves several steps:

Physical Examination

Your veterinarian will perform a thorough physical exam, observing your dog’s gait and manipulating the hips to check for pain, reduced range of motion, and joint laxity. This initial assessment helps determine if further diagnostic tests are necessary.

Radiographs (X-rays)

X-rays are the primary tool for diagnosing hip dysplasia. They allow veterinarians to visualize the hip joint structure and assess the degree of joint malformation, subluxation (partial dislocation), and arthritis. For accurate imaging, dogs typically require sedation or anesthesia to properly position their hips.

Other Diagnostic Tools

In some cases, additional diagnostic methods may be employed:

• Computed Tomography (CT) scans: Provides more detailed images of bone structure
• Magnetic Resonance Imaging (MRI): Helps assess soft tissue damage around the joint
• Joint fluid analysis: Can help rule out other conditions that cause similar symptoms

Treatment Options for Hip Dysplasia

Treatment approaches for hip dysplasia vary based on the severity of the condition, the dog’s age, size, and overall health status. A comprehensive treatment plan often combines multiple strategies:

Conservative Management

For mild to moderate cases, non-surgical approaches may be effective in managing symptoms:

Weight Management

Maintaining an optimal weight is crucial for dogs with hip dysplasia. Excess weight places additional stress on already compromised joints, exacerbating pain and accelerating joint degeneration. Your veterinarian can help determine an appropriate weight for your dog and develop a safe weight loss plan if needed.

Exercise Modification

While exercise is important for maintaining muscle mass and joint mobility, the type and intensity should be carefully controlled. Low-impact activities like swimming and controlled leash walking are ideal, while high-impact exercises like jumping and rough play should be avoided.

Physical Therapy

Canine physical therapy techniques can significantly improve mobility and reduce pain. These may include:

• Therapeutic exercises to strengthen supporting muscles
• Hydrotherapy for low-impact strengthening
• Massage to reduce muscle tension
• Heat and cold therapy to manage pain and inflammation

Medications

Various medications may be prescribed to manage pain and inflammation:

• Nonsteroidal anti-inflammatory drugs (NSAIDs): Help reduce pain and inflammation
• Joint supplements: Glucosamine and chondroitin to support cartilage health
• Omega-3 fatty acids: Have anti-inflammatory properties that may benefit affected joints
• Pain medications: For additional pain relief when NSAIDs aren’t sufficient

Surgical Options

When conservative management doesn’t provide adequate relief, or in severe cases, surgical intervention may be recommended:

Juvenile Pubic Symphysiodesis (JPS)

This preventive procedure is performed on puppies younger than 5 months who are at high risk for developing hip dysplasia. It involves fusing a growth plate in the pelvis to allow the hip socket to develop more favorably as the puppy grows.

Double or Triple Pelvic Osteotomy (DPO/TPO)

Typically performed in young dogs before arthritis develops, this procedure involves cutting the pelvic bone and rotating the segments to improve the fit of the ball and socket joint.

Femoral Head Ostectomy (FHO)

This surgery involves removing the ball portion of the hip joint, allowing scar tissue to form a false joint. While this doesn’t restore normal hip function, it can significantly reduce pain. FHO is often more suitable for smaller dogs or as a salvage procedure when other options aren’t feasible.

Total Hip Replacement (THR)

Considered the gold standard surgical treatment, THR involves replacing both the ball and socket with prosthetic implants. This procedure can restore near-normal function and eliminate pain but is typically reserved for adult dogs with severe hip dysplasia and refractory pain.

Living with a Dog with Hip Dysplasia

With proper management, dogs with hip dysplasia can lead comfortable, active lives. Here are some tips for caring for a dog with this condition:

Home Modifications

• Provide orthopedic bedding to cushion joints and ease pressure points
• Use ramps or steps to help your dog access furniture or cars
• Place food and water bowls at an elevated position to reduce strain while eating
• Install carpet runners or yoga mats on slippery floors to prevent slipping

Ongoing Care

Regular veterinary check-ups are essential to monitor the progression of the condition and adjust treatment as needed. Your vet may recommend periodic x-rays to assess joint changes over time.

Preventing Hip Dysplasia

While not all cases of hip dysplasia can be prevented due to genetic factors, several steps can reduce the risk or minimize the severity:

Responsible Breeding

If you’re considering getting a puppy from a breed predisposed to hip dysplasia, choose a reputable breeder who screens breeding stock for hip dysplasia using organizations like the Orthopedic Foundation for Animals (OFA) or PennHIP.

Proper Nutrition

Feed large-breed puppies specially formulated large-breed puppy food that controls growth rate and provides balanced nutrition. Avoid over-supplementation with calcium or vitamins, which can contribute to skeletal abnormalities.

Appropriate Exercise

During growth periods, limit high-impact activities and focus on controlled exercise that builds muscle without stressing developing joints.
