Hip joint disease.

The Border Collie is a healthy breed, however, like all animals, there are some hidden diseases. The current basic genetic diseases in the Border Collie breed are as follows:

HIP DYSPLASIA, the English abbreviation is HD (also called HIP JOINT DYSPLASIA, the English abbreviation HIP. Chinese: hip joint disease)

HD is the most common genetic disorder affecting Border Collies. As HD progresses, it will eventually lead to hip necrosis. Damage to the hip joint is called osteoarthritis, also known as degenerative joint disease (DJD), which is manifested in a combination of rickets, osteoporosis, and abnormal bone growth in the hip joint due to gravity and strenuous exercise. .

In fact, the confirmed result of DJD is that it directly leads to HD. The most definitive method of diagnosing HD remains X-ray of the hind leg extensions. For example, the Orthopedic Association for Animals (OFA).

OFA reports that 12.6% of Border Collies diagnosed from 1974-2000 suffered from this disease. HD ranks somewhere in the middle of the range of all dog breed diseases. OFA's reported results are influenced by veterinarians and breeders, and the percentage of reported results is greatly reduced.

Therefore, the actual impact of this disease may be very high, basically more than double the number reported by OFA, that is, on average, 1/4 of Border Collies have this disease.
