"Guide to Hip Dysplasia in Dogs"
Introduction
Canine hip dysplasia (CHD) is one of the most challenging diseases in veterinary medicine today. This developmental disorder affects the hip joints of dogs, leading to pain, discomfort, and eventually arthritis. Understanding the causes, recognizing the symptoms, and exploring the available treatment options are crucial steps in managing this condition effectively. This guide provides a comprehensive overview of CHD, aiming to help dog owners make informed decisions to improve their pets' quality of life.

What is Canine Hip Dysplasia (CHD)?
Canine hip dysplasia (CHD) is a developmental disorder where the ball and socket joint of the hip do not fit or develop properly. This results in joint deterioration, leading to cartilage damage, inflammation, pain, and swelling. It is the most common cause of hip arthritis in dogs.
How is Canine Hip Dysplasia Transmitted?
CHD is a heritable disease, passed from parents to their offspring. Preventing dogs with hip dysplasia from breeding is the only effective way to eliminate the disease from the gene pool. However, this is challenging because not all dogs with CHD show symptoms, and seemingly normal dogs may carry the gene for CHD and pass it on to their offspring.
Symptoms of Canine Hip Dysplasia
- Reduced energy and movement
- Difficulty rising from a sitting position
- Weakness in the hind legs
- Bunny-hopping gait when running
- Reluctance to climb stairs
These symptoms often become apparent in middle-aged dogs, although severe cases can show signs as early as 5-6 months.
Diagnosis of Hip Dysplasia
Currently, no blood or genetic test is available to detect CHD. Diagnosis is typically made through physical examinations and X-rays. Two common X-ray techniques used are:
1. Hip-Extended Ventrodorsal View X-ray: Provides a frontal view of the pelvis and hip joints to assess the severity of arthritis.
2. PennHIP Radiography Procedure: Detects hip laxity in dogs as young as four months old.
Treatment Options for Canine Hip Dysplasia
Conservative (Non-Surgical) Treatments
- Medications: Pain and inflammation can be managed with medications like Rimadyl, Etogesic, and Deramaxx.
- Weight Management: Maintaining a healthy weight reduces stress on the hips.
- Controlled Exercise and Physical Therapy: Can improve joint function and reduce pain.
Surgical Treatments
When conservative treatments are insufficient, surgical options can be considered:
1. Preventive Surgeries:
- Triple Pelvic Osteotomy (TPO): Involves cutting the pelvis in three places and rotating the hip sockets to improve coverage. Effective if performed before arthritis sets in.
- Juvenile Pubic Symphysiodesis (JPS): Involves altering pelvic growth to ensure tighter hips. This procedure is still under evaluation and is done on very young dogs.
2. Therapeutic Surgeries:
- Total Hip Replacement (THR): This involves replacing the hip joint with a high-density plastic socket and a non-corrosive metal ball. This procedure has a high success rate and nearly eliminates pain.
- Femoral Head Ostectomy (FHO): Involves removing the head of the femur, allowing a false joint to form from scar tissue. Generally recommended for smaller, well-muscled dogs.
Prevention of Canine Hip Dysplasia
- Selective Breeding: Avoid breeding dogs known to have CHD.
- Weight Management: Prevent excessive weight gain in puppies to reduce stress on developing hips.
- Proper Exercise: Ensure that puppies do not engage in activities that put undue stress on their hips.
Summary
Hip dysplasia is a common and challenging condition in dogs, primarily due to its heritable nature and the difficulty in preventing and treating it. Recognizing the symptoms early, proper diagnosis through physical exams and X-rays, and considering both conservative and surgical treatment options are essential in managing this condition. Preventative measures such as selective breeding and maintaining a healthy weight in dogs can help reduce the incidence of CHD.
