Coxofemoral Dysplasia in dogs is a common, genetic disease that can considerably affect a dog's quality of life.
Also known as hip dysplasia, this orthopaedic disease is characterized by a poor fit between the head of the dog's femur and its pelvis, which form the hip joint.
In a normal condition, this hip joint functions as a kind of socket, but in hip dysplasia in dogs, there is a malformation that prevents it from fitting together in the right way.
Thus, there is constant friction between these bones, which causes wear and inflammation in the area, which consequently causes pain in the dog.
This pain can become chronic and even lead to a gradual loss of joint function. In other words, limitation or loss of mobility for the dog.
Hip dysplasia in dogs is not curable, but by treating it properly and following up with a veterinarian, we can control the symptoms and avoid serious conditions.
Causes of Coxofemoral Dysplasia in dogs
Hip dysplasia in dogs is a disease with multiple factors. The disease is genetic and chronic, which means that the puppy is born with a genetic predisposition, passed down from father to son.
"With up to 51.9% of dogs of certain breeds affected by hip dysplasia, studies highlight the need for radiographic screening and rigorous genetic selection. These measures are essential for reducing the incidence of the disease and ensuring a better quality of life for animals," explains Bianca Franzoni, head veterinarian at PetMoreTime.
Breeds with a higher incidence of hip dysplasia:
- German Shepherd
- Labrador
- Rottweiler
- Golden Retriever
- Pitbull
- São Bernardo
- Siberian Husky
- Cane Corso
Many small dogs, however, also have this predisposition, such as the Cavalier King Charles Spaniel breed.
In addition, many of the dog's external factors (environment, daily life) can influence the symptoms of Coxofemoral Dysplasia.
These include the dog's nutrition . For example, puppies that are fed too many calories as puppies end up growing at an accelerated rate and this can hinder the correct development of the hip joints. This is especially true of large breed puppies.
Therefore, always invest in veterinary care and ask them to recommend a balanced diet specifically for your dog.
Another factor that can very often lead to stress in a dog's joints and trigger dysplasia is obesity. Excessive weight gain can anticipate the onset of symptoms in the dog.
Lack of physical exercise and high-impact activities are factors that damage the hip joint. On the one hand, a sedentary lifestyle compromises not only the dog's quality of life, but also the proper development of this joint. On the other hand, repetitive high-impact exercise - such as excessive running, slippery floors that lead to slipping or frequent jumping - can cause injuries and accelerate wear and tear on the joint.
Other factors such as the animal's body conformation and conditions of ligament weakness are associated with a greater likelihood of hip dysplasia.
Symptoms of hip dysplasia in dogs
Dysplasia doesn't appear overnight - it shows signs over time, and the sooner you identify it, the better your four-legged friend's quality of life will be.
Let's understand together how to recognize the symptoms at each stage.
- Decreased activity and endurance
- Difficulty getting around
- Lameness
- Hip pain
- Sensitivity in the hip area
- Constant popping in the hip
- Abnormal posture
- Abnormal movements
- Muscle loss in the hind legs
- Frequent falls
- Arthrosis
Warning: Many of these symptoms can begin mildly and gradually progress.
Some dogs disguise their pain well! If you notice any change in your pet's behavior, don't wait for it to get worse. Dysplasia can be treated, and the sooner you start, the more comfort you'll be able to offer your best friend.
How is the diagnosis made?
The diagnosis of hip dysplasia is made through clinical assessment and imaging tests. Initially, the vet will carry out an orthopedic physical examination, which may include tests such as Ortolani's to detect joint laxity.
Confirmation is made mainly through X-rays of the pelvis and hips, which show the conformation of the bones and the degree of incongruity, as well as identifying arthrosis or other lesions.
In puppies, techniques such as the PennHIP method allow for early screening, but definitive diagnosis usually occurs when the animal reaches skeletal maturity (around 1.5 to 2 years).
Treatments for Coxofemoral Dysplasia in dogs
Hip dysplasia has no definitive cure, but there are several approaches to improving your pet's quality of life.
Treatment is always personalized and varies according to the degree of dysplasia, the age and conditioning of the animal.
Regardless of the approach chosen, treatment should be guided by a veterinarian and may combine several of these strategies.
Remember that dysplasia is a chronic condition, where the aim is to control pain and preserve joint function throughout the animal's life. With proper management, many dogs are able to lead comfortable and happy lives.
Check out the main options:
1. Weight control and diet
Keeping your dog at a healthy weight is essential. A balanced diet, with quality food containing natural chondroprotectors - such as glucosamine and chondroitin - helps to reduce the strain on the joints. Weight loss, when necessary, can relieve symptoms and improve mobility.
2. Controlled Exercise and Physiotherapy
Low-impact activities such as moderate walking and swimming are ideal for strengthening the muscles without damaging the joints. Physiotherapy, with resources such as stretching, hydrotherapy, massage and alternative therapies (acupuncture, laser therapy and magnetotherapy), helps to increase range of movement and reduce pain.
3. Medication and supplementation
The use of analgesics and non-steroidal anti-inflammatory drugs (NSAIDs) is common to control pain. In addition, injectable chondroprotective drugs and dietary supplements - containing glucosamine, chondroitin, omega-3, type II collagen, MSM and hyaluronic acid - are recommended to nourish the joint and slow down the progression of arthrosis.
4. Surgical treatment
In the most serious cases, when the animal has intense pain or severe limitations, it may be necessary to resort to surgery. Options include:
- Total hip replacement: replacement of the joint with artificial implants, ideal for medium to large adult dogs with severe dysplasia.
- Osteotomies: procedures that adjust the angle of the pelvis or remove the head of the femur to reduce bone contact and relieve pain.
- Procedures on young animals: such as the triple pelvic osteotomy, which helps to improve the fit of the hip while the pet is still developing.
Prevention of hip dysplasia in dogs
Although hip dysplasia has a strong genetic basis and cannot be prevented in all cases, adopting preventive measures can significantly reduce the risks, delay the onset of symptoms or even mitigate the severity of the disease. Here are the main recommendations:
- When buying a puppy, research the history of the parents and grandparents. Serious breeders carry out X-ray tests to identify dysplasia in breeding stock, ensuring that only animals with healthy hips are bred.
- Invest in a balanced diet, suitable for the age and size of the pet. Large-breed puppies, for example, need specially formulated food to avoid accelerated growth that puts a strain on their joints.
- Avoid obesity, which can aggravate joint problems. Monitor their diet, limit snacks and leftovers and consult your vet if you notice excessive weight gain.
- Promote regular low-impact activities such as walking, controlled play and swimming. A sedentary lifestyle damages the muscles that support the joints, but excessive effort, especially in puppies, can cause damage.
- In addition, create a friendly environment for your pet's joints. Non-slip floors, rugs and the use of ramps instead of steps can prevent slips and micro-injuries.
- Additionally, under veterinary supervision, the use of supplements such as type II collagen, glucosamine, chondroitin and omega-3 can be started as a preventative measure to strengthen cartilage and improve joint lubrication.
- Finally, go for regular check-ups, even if your dog seems healthy. Regular visits to the vet are essential to identify any changes in the hip at an early stage.
In predisposed breeds, preventive radiographic examinations at around 1 year of age can detect changes even before symptoms appear.
If you notice symptoms, see a vet, limit intense physical activity, don't self-medicate your dog and follow professional advice.
Adopting these practices doesn't eliminate the genetic risk, but it does promote a healthier life for your dog, delaying the onset of symptoms and ensuring more effective management should dysplasia manifest itself.
After all, a well-cared for and monitored pet is much more likely to enjoy an active and comfortable life!
