Summary :	Ground reaction forces of the rear limbs were registred in 11 walking young adult military german shepherds. Each dog was operational. Based on the X rays (standard positioning) and the FCI classification, the dogs were separated into two groups 1 : Group 1 : dogs quoted A or B, Group 2 : dogs quoted C, D, or E. A piezzo electrical force plate was used for registration, every millisecond, during 4000 milliseconds. The vertical maximal force was calculated, and divided by the body weight. For each dog, 5 valid registrations were selected for calculation of vertical maximal force. A mean value comparative statistic test showed a significant difference between the two groups. The results show that the dysplastic dogs, though they were not clinically impaired, had significantly lower vertical forces than normal dogs. However the results cannot be used on an individual scale for a predictive evaluation concerning hip dysplasia.
