The hip dysplasia is a very common problem in certain breeds: BullDog, Dogue de Bordeaux, San Bernardo, Neapolitan Mastiff, German Shepherd Dog, Rottweiler, Golden? all of them have an incidence above 20%.
Dysplasia is a multifactorial, Multigene and hereditary disease, i.e., several factors that predispose and cause hip dysplasia, there are several genes involved in its appearance and has hereditary nature.
Environmental factors increasingly are more important in the development of hip dysplasia, the genetic factor is necessary to develop the disease, but this is not the only factor. Genetics is a necessary but not exclusive factor, i.e. you can have genetic predisposition and not develop the disease, but if there is no predisposition unsure that it develops.
There are various grades of Dysplasia, and also those that appear when the dog is a puppy or give that problem already in adulthood; but in this article, we will focus on treatment and specifically in the treatment of dysplasia to young dogs.
Classification of the degrees of dysplasia according to the OFA:
Grade I: minimum alteration with small subluxation and degenerative changes little.
Grade II: marked lateral subluxation of the femoral head, whose 25-50% is out of the acetabulum.
Grade III: 50-75% of the femoral head is out of the acetabulum; There are important degenerative changes.
Grade IV: dislocation of the femoral head with flattening of the edge acetabular and femoral head; There are important degenerative changes.
The presentation in the young dog is usually between 5 and 6 months and It is marked by a significant limp.
Is not that a dog is free from dysplasia until two years old already fulfilled are not observed problems or inconsistencies in control x-rays.
Food is one of the factors predisposing to the emergence of Hip Dysplasia, imbalances calcium-phosphorous, which should save a Ca1.6% correlation? P1.1% and above all do not overfeed or bring in excess protein allows us to minimize the incidence of hip dysplasia. A hypocaloric diet 3 months and up to 8 months protects above all dysplasiadogs with rapid growth. Overweight 60 days is another factor that predisposes to disease.
Dysplasia of hip in the puppy normally Debuts from 5 or 6 months, before it is not possible to observe any problems and the dog has been completely normal and has developed normally. The debut is often present as acute lameness that prevents the dog to play as he had done to date. We can observe changes in the desire to play, negative at the time of leaving ride, interact with other dogs or owners. Do do are frequent mood swings, frequent slips of the hind legs, discomfort and even refuse to be touched and the fact of? flee? children in dogs that until recently few days were playful and affectionate.
Sometimes to meet 90% of the growth between 8 and 11 months the signs can be reduced and even get to disappear. Anyway the dysplasia remains and in many cases the problems reappear after a while and sooner rather that later appear signs of osteoarthritis in hips.
The most common clinical signs are:
Lameness that may increase with exercise
Walking and jogging with rolling hips
Difficulty getting up
Refusal to move
Changes in the mood
Although there are surgical methods: excision of the pectineus muscle, triple osteotomy of Hip Arthroplasty in the femoral head, pubic, forage, prosthetic hip osteotomy most practiced when the dog is young for, supposedly to reduce the possibility of secondary hip arthritis in adulthood. Hip prosthesis should be reserved for serious cases and once completed growth.
Do medical treatment is based on anti-inflammatory drugs, we can start with natural anti-inflammatories, which does not contain substances drug, if we do not get the expected results go to NSAIDs? s and in extreme cases is tenement uses. We must include nutraceuticals above all the chondroprotectors since they reduce the incidence of osteoarthritis and protect cartilage joint. These are used in senior dogs in a very general way, but are very useful as protective joint in growing dogsThere are specific condroportectores for young dogs. Moderate exercise, weight reduction and above all regular they are others of the basics, as well as improvements in the environment and sleeping in a place warm and away from moisture.
Physical therapy can greatly help develop better muscle to reduce pain, to remove tensions and to eliminate compensation that the dog has done with the incorrect postures and positions analgesic. This will be based on TENS, Ultrasonictherapeutic exercises, the use of hydrotherapy, laser, shock wave? for more information we refer to this Article.
The main improvement in the environment is to sleep in a good therapeutic mattressmove not cold nor exposed to high humidity, use in winter a blanketto be a therapeutic blanket that it can be used all year round.
We can help in many way our dog with dysplasia, exercise physical regular can be very useful to improve muscle mass that makes better support poor congruence articulate, avoid impacts, jumping or racing descontrolas during the presentation of the box are also important elements. Physiotherapy and massages allows to always have the dog on a good muscular condition, and all interveners treatments such as acupuncture, massage, reiki, bach flowers? they can also collaborate in the treatment. The latest novelty are the Hip supports They help to stabilize the pelvis, support and improve the quality of life for our pets a lot.
