Hips dysplasia (HD) is state involving abnormal cavity of the head of femoral bone into the cup pelvic bone, accompanied by degeneration of articular surfaces on both, and the hem of the pan as well as the flattening of the femoral head. The important thing in dysplasia is that the animals are born with absolutely healthy joints and dysplasia is a feature of growing due to the growth and usage of the hip joints. Cynological organizations for many dog ​​breeds have introduced mandatory testing of breeding animals using X-ray for hip dysplasia before granting the status of  breeding dog. The minimum age to perform X-ray of the entry in the pedigree is completed 12 months of life.

But let's move on to the merits of this or what causes dysplasia.


As we know culture they can not be used in dogs with hips dysplasia. Is permissible only result HD A, B and C. With dysplasia is considered unacceptable HD D and E by classification. Why ??? Namely, the researchers found that this is a feature that animals can inherit. Recent advances geneticists confirm that there are two genes  HIPLAXITY 1 and 2, which are conducive to the formation of dysplasia. These genes are responsible for the creation of a specific laxness in hip, associated with a lower elasticity and poor construction of the ligament of the femoral head, which during the development of the puppy pulls the femoral head to the acetabulum by promoting normal development of the hip joints. Loose ligaments and delayed bone mineralization causes during sudden movements so typical for puppies during development, injury and subluxation of the joints, and this leads to further developmental disorders and degenerative changes in the joints.


What about the animals that are genetically free of both genes, and yet it occurred in their dysplasia ??? Exactly puppies born to physiological all with loose joints, including hip joints, and with the development of binding of the soft tissue and strengthening of joint connections. In this important period for the development of the most important is nutrition, animal welfare and how important usage. During the growth and excessive burden puppies (overfed animals, fast-paced growth) any abnormal movement, at the same time continuing poor muscle mass can affect the joints and damage microtrauma, which causes inflammation and leads to degenerative changes in the joints. In this way, for 12 months of development puppies after they have been further trauma hip dysplasia acquire a traumatic dysplasia. Unfortunately, the X-ray image, it looks exactly the same because both dysplasia and development is performed similarly.


The first symptoms of hip dysplasia can occur in dogs 6 months of age. But I met in my practice, that pain symptoms do even shows by 3-month-old babies. Most often what should worry the owner ???

- Lameness  one hind leg or the so-called "strange gait"

- Lameness "cold" or signs of lameness on not working joints

- Laying narrow hind limb in gait

- Tripping croup (shortened stride pelvic limbs)

- "Shooting" in the hip joints

- Difficulty climbing stairs

- Running in a manner reminiscent "rabbit movement"

- Reluctance to abduction hind leg

- Atrophy of muscles of the hindquarters or weak their built


For the prevention of hip dysplasia apply some basic rules:

1. Optimal feeding

Nutrition is to ensure the proper development of a dog at the same time as little encumbrance of developing arthritis. Food should be balanced, high-quality, but overfeeding animals is the first step to dysplasia. Some breeds at the age of puppyhood, eg german shepherd are conducted "in thinness" precisely because of the prevention of dysplasia.

2. supplementation

The use of supplements to support joint function and strengthen the ligaments and tendons.

3. The competent traffic in appropriate quantity

Avoiding traffic is the biggest mistake owners of puppies. The proper development of muscle mass is conducive to maintaining the joints in the physiological position, preventing injuries and dislocation.

Proper motion is the plane most of trot, uniform motion, no sudden turns, jumps, jump onto the obstacles. It is a movement appropriate for the development of muscle mass, and on the other hand does not cause injuries.

Similarly, walking up the stairs is necessary, but in the right way which inched / without jumping.
