Correction of Anecdotal Misinformation
- There are no environmental factors which cause CHD (Canine Hip Dysplasia)
- There is no evidence in the scientific literature that megadoses of Vitamin C or any other supplement is beneficial in reducing the effects or preventing CHD.
- High caloric intake resulting in rapid growth and increase weight gain may exacerbate changes in dysplastic hips but will not create hip dysplasia.
- Exercise, running, jumping up and down, and slick floors will not cause hip dysplasia.
- Prior injuries to the femurs and/or pelvis may be detected radiographically and are taken into account when evaluating hip status.
