To assess whether fully normalised vertical ground reaction forces and stance times obtained at a trot depend on dog breed or body conformations.Peak (PVF), impulses (VI), (ST), ratio of forelimb impulse to total (RVI) 54 dogs seven different breeds were weight size according the theory dynamic similarity, tested for differences between breeds. Breeds Borzoi, Bernese Mountain dog, Great Dane, Labrador Retriever, Landseer, Rhodesian Ridgeback, Rottweiler. Body length (BLR) mass index (BMI) also compared breeds.Significant found PVF, VI ST, hindlimb PVF. Looking individual breeds, it was most evident that Borzois had lower VI, higher PVF than other This resulted in having RVI dogs, indicating more caudally located centre gravity. Only few gait parameters The BMI significantly but otherwise not associated with parameters.Force plate data are necessarily comparable, even after full normalisation size. Group comparisons should only be made when groups consist similar conformations.
