Hip dysplasia can occur in any breed of dog and is an abnormal formation of one or both of a dog's hips, this can lead to them experiencing pain or discomfort whenever they exercise or change position. Here, our Danbury vets discuss the causes, signs, and treatment options of hip dysplasia in dogs, and how surgery can help treat it.
Canine Hip Dysplasia
Your dog’s hip joints work like a ball and socket. Hip dysplasia is an abnormal development of one or both of your pup's hips. When dogs are diagnosed with hip dysplasia, the ball and socket that makes up their hip hasn't developed properly and are not working as they are supposed to. Instead, the ball and socket rub and grind against each other, causing a breakdown over time and potentially causing an eventual loss of function in the impacted hip joint.
While hip dysplasia is most commonly seen in giant or large breed dogs, smaller breeds can also suffer from this painful condition. If left untreated hip dysplasia can drastically reduce your dog's quality of life, as the condition causes pain and reduces your dog's ability to move normally. Hip dysplasia is also very difficult for pet parents to deal with since it can be very upsetting to watch an otherwise healthy dog deal with the symptoms of this condition
Causes of Hip Dysplasia in Dogs
Generally, hip dysplasia is a hereditary condition, with genetics being the most common cause of this condition in dogs. Hip dysplasia is seen more frequently in giant breeds and large dogs such as Rottweilers, Mastiffs, St. Bernards, retrievers, and bulldogs, although a handful of smaller breeds such as French bulldogs and pugs are also susceptible.
If this condition goes without treatment in its earlier stages it can continue to get worse with age and affect both hips (bilateral). Hip dysplasia could be compounded by other painful conditions such as osteoarthritis in senior dogs.
Even though hip dysplasia is an inherited condition, there are other contributing factors that could exacerbate the genetic predisposition. Improper weight and nutrition, accelerated growth rate, and some types of exercise can all factor into the development of this condition. Obesity puts abnormal stress on your dog’s joints and may aggravate pre-existing hip dysplasia or even cause the condition.
Regardless of which breed of dog you own, it’s important to consult your vet regarding the right amount of daily exercise for your pup, and the most appropriate diet for their age, size, and breed.
Signs of Hip Dysplasia in Dogs
Every dog is different in terms of the symptoms they display of hip dysplasia however, the condition usually starts to develop when dogs are still a puppy around the age of five months old. Although the signs may not be obvious until they reach middle age or their senior years. Dog owners should keep an eye out for these symptoms as their puppy enters adulthood:
- Stiff back legs when walking
- Signs of discomfort or pain while exercising (or a reluctance to exercise, run, jump, or climb stairs)
- Stiffness when running or rising from a resting position
- Running with a 'bunny hop'
- Loss of muscle tone in back legs or thighs
- Lameness in the hind end
- Decreased range of motion
- Grating or grinding of the joint when they move
Diagnosing Hip Dysplasia in Dogs
Hip dysplasia is just one of the many common conditions that vets look for when they are examining a dog during a routine checkup. At your pup’s regular physical exams, your veterinarian will check your dog's overall physical health and the condition of their joints. Your vet may move your dog’s hind legs to identify any grinding sounds, signs of pain, or reduced range of motion. If your vet believes that your dog might have hip dysplasia, they could recommend blood tests that will be able to detect inflammation as a result of joint disease.
Your vet will also request your dog’s complete health and medical history including a rundown of specific symptoms, and any injuries that may have caused them. Knowing your pet’s lineage can offer insights into your dog's likelihood of developing hip dysplasia. Standard X-rays can also be very helpful in diagnosing the severity of your dog's hip dysplasia, and to chart a course of action for treatment.
Treating Canine Hip Dysplasia
The treatment options available for dogs with hip dysplasia will vary depending on the severity of their condition, from changes in lifestyle such as diet and exercise to pain meds and surgery.
Surgical Treatment Options
When treating hip dysplasia in dogs, there are 3 main surgical options available:
Femoral Head Ostectomy (FHO)
FHO can benefit both young and mature dogs. This type of surgery entails removing the femoral head (ball) of the hip joint, allowing the body to create a “false” joint, which decreases the discomfort related to hip dysplasia. Dogs undergoing FHO will not see the return of normal hip function; however, it can be an effective method of managing pain.
While factors such as the size and age of your dog, as well as the severity of the condition, will all affect the price of FHO surgery. The cost of the surgery will include pre-surgical bloodwork, the procedure, anesthesia, post-surgical care, and medication.
Following surgery, your dog could be required to remain in the hospital for anywhere between several hours and several days, depending on their health, and other factors. Your veterinary surgeon will provide you with specific instructions for caring for your dog after FHO surgery, but you will need to prevent your dog from doing any strenuous physical activity for at least 30 days. In most cases, you can expect your pup to completely recover about six weeks following the operation. Once fully recovered they can resume regular physical activity.
Double or triple pelvic osteotomy (DPO/TPO)
These hip surgeries are most commonly performed in dogs under 10 months old and involve cutting the pelvic bone in specific locations and then rotating the segments, resulting in an improvement of the ball and socket joint.
Following these surgeries, your pooch will require several weeks before they'll be able to enjoy proper leash walks again, and will need regular physical rehabilitation (physio for dogs) for full mobility to return (although you may notice joint stability improve within as little as four weeks). Most dogs will recover within four to six weeks after DPO/TPO surgery.
Total Hip Replacement (THR)
Total hip replacement is typically the first choice for surgical treatment of hip dysplasia in dogs, since it is the most effective. THR involves using plastic and metal implants to replace the entire hip joint, bringing hip function back to a more normal range and eliminating most hip dysplasia-related discomfort.
That said, THP surgery is a drastic option and the most expensive. This surgery is usually recommended if the dog is in considerable pain or close to completely immobile. The artificial components used in THR must be custom-made for your dog, and the surgery is performed by certified veterinary surgeons.
Total hip replacement surgery usually takes about two to three hours, and your dog may need to be hospitalized for one to three days following surgery. To ensure proper healing, expect a 12-week recovery period. Even if your dog's hip dysplasia appears in both hips, surgery may only be performed on one hip at a time, allowing a three-to-six-month gap between procedures.
Our vets understand that hearing a diagnosis of hip dysplasia in your dog can be heart-wrenching, as the condition is painful and can visibly reduce mobility. This diagnosis can also cause some financial concerns as surgical options can impact your budget. That said, your veterinarian may be able to recommend an option or combination of treatments that can help your dog recover and regain some of their hip function.
