Hip Dysplasia Research
For those of you interested in learning more about hip dysplasia, we recently reviewed some research and pulled some insights for you. From what we gathered, it is important to keep your dog 'on the lean side' and not overweight.
Facts from the source: http://cal.vet.upenn.edu/projects/saortho/chapter_83/83mast.htm
- Hip dysplasia is a complex range of environmental and body conformation and hereditary factors. Hip dysplasia in dogs has no clear-cut pattern of inheritance (although it can be greatly reduced by attempting to control it with breeding stock without HD). Environmental factors must be considered with body conformation as causes.
- Heritability (in a study) has been shown at a rate of 25%.
- Most dogs will be between the ages of 5 months - 12 months at first presentation.
- Hip dysplasia affects humans and other domestic animals. 1.3 human children out of 1000 are affected.
- In humans, females are 4 to 8 times more likely to have hip dysplasia. In dogs, it is equal by gender.
- In a study, pups that overate and ate 'aggressively' (pushing hard with back legs to latch to the mother) - the majority (63%) were dysplastic at 1 year of age.
- The body conformation of breeds with the lowest prevalence is slender and trim. Overweight and giant dogs have the highest.
- Hip dysplasia has not been reported in wild animals such as wolves and foxes. The pups are slow growing and of late maturity.
- Past pedigree history is of little relevance, since many generations may be normal and still produce dysplastic progeny.

- The rate of growth in a puppy is a primary factor in the development of hip dysplasia.
- No breeder can eliminate ALL risk of hip dysplasia. The average 'german' German Shepherd will show 10 to 15 generations of clean hips before 1 shows with hip dysplasia.
