Occurs with a bad cavity congruence acetabular (hip) with the femoral heads that can appear luxated or sub luxadas, i.e. outside its natural place. Do the head of femur by not having a good coating? dance? and this produces stress, inflamed and weakens the joint and periarticular tissues.
It is very frequent to appear degenerative changes of osteoarthrosis. The osteoratrosis which appears due to dysplasia will cause inflammation, pain, problems which, in turn, will make the dog load more weight on hands, less in the rear and therefore use less subsequent and displayed a clear muscle atrophy in the posterior third that aggravate symptoms.
The symptoms vary a bit depending on the race, and above all of the age of the dog, we think that for diagnostic radiography to distraction, i.e. with the dog lying upwards and symmetrical traction on the hind limbs, usually with very sedated or anesthetized dog, but not always symptoms correlate with the results of the x-ray.
Sometimes see dogs with much dysplasia and presenting little pain or even nothing and also the otherwise much pain with a result in the radiological examination that is not so bad. Pain depends more on the joint inflammation (SYNOVITIS) among other factors than dysplasia itself.
From 5 or 6 months, begin the signs of warning, the dog is worse (pulls a leg toward outside), has difficulty standing, no weight is on the rear, can have signs of pain after exercise, slip, fall, sudden mood change, become more aggressive, shy away from the presence of the owner when petting him and present the typical dog with dysplasia which is rolling back March and the career as a rabbit. Sometimes at the end of the growth the symptoms disappear or are minimized, leaving as the only sign clear progress in rolling.
Hip Dysplasia has clear indices of heritability, although many times dogs are carriers but do not develop hip dysplasia, all the factors, both genetic and environmental as rapid development and nutrition and their mechanisms of action are not clear and we see children with normal parents and even vice versa hip dysplasia, although it is not very ethical to make raising sick parents.
Excess weight, not varied diet where dogs can choose are factors that have been shown to increase the chances of developing the disease. The most critical period of the development of this disease is between 3 and 8 months, the reduction of caloric intake and regular exercise without much impact could be an interesting decision to prevent Dysplasia of hip in this phase.
In older dogs, problems are determined as a result of osteoarthritis that present, symptoms more typical are the difficulty to get up, the March in swinging of the hips, look that much more loadweight front and steps helping the forelimbs (paddling rather than propelling), they have many difficulties to put on the rear, stairs, entering the car or get on the sofa. In the image we can see the typical position that adopts a dog with hip osteoarthritis, with legs open to increase the base of support and head forward to carry more weight in the front, also you can see the muscle atrophy that exists in the subsequent.
Sometimes present lameness that disappears after a short period of time, is suffering more in the morning when you get up especially if you have not rested properly or on a suitable mattress walking, limb usually them placed bent as they walk, his steps are short since it hurts the extension of the hips and presented a development of muscle mass in the posterior (atrophy) very important. Times of rides are much reduced, the dog sits or lies down and does not want to go for a walk or to much during the ride.
Although there are different classifications, the International Canine Federation is based on this classification:
Do although there are surgical methods: excision of muscle pectineus, triple osteotomy of the femoral head, forage, hip prosthesis Arthroplasty, hip? at the end is purely palliative, includes Pharmacology: anti-inflammatory and protective cartilage, reduction of weight, moderate exercise and above all regular, physical therapy can greatly help develop betterthe muscles without pain to remove tensions and to eliminate compensation that the dog has made, improvements in the environment: sleep in a good mattress for example the mattress for older dogscold or exposure to high humidity, and all interveners treatments such as acupuncture, massage, reiki, bach flower remedies?
We can help our dog with hip dysplasia in many way, regular physical exercise We can greatly help improve muscle mass that can make us better support poor congruence articulate, physiotherapy and massages allow to keep the dog in a correct state of muscle, cartilage guards delayed the onset of osteoarthritis, anti-inflammatory drugs prevent or reduce pain, we can protect your dog from the cold with thermal blankets and in the event that the dog cost rise help you with harness for rear, is important that dogyou feel comfortable and stimulate him to move and exercise.
