Introduction: Dog boots are being utilized to improve performance and welfare of dogs exposed to a range of adverse conditions; however, there is a lack of empirical evidence establishing the impact of these on gait characteristics. The aim of this research was to quantify alterations to ground force kinetics associated with the introduction of canine boots. Methods: Six clinically sound beagles were analyzed on two separate occasions using a cross-over study design to enable randomization between barefoot and shod conditions. During each session, dogs were trotted by an experienced handler over an AMTI force plate sampling at 1,000 Hz to quantify stance time, peak vertical force, peak vertical instantaneous loading rate, and vertical impulse. Results: Although there was no significant difference found between footwear conditions for stance time, peak vertical force, and vertical impulse, peak vertical instantaneous loading rate was significantly greater in shod when compared to barefoot. Discussion: Findings suggest that while canine boots may provide environmental protection, increases in loading rate are indicative of alterations in foot strike that may result in overloading of musculoskeletal structures. Therefore, caution must be taken when introducing footwear to ensure an adequate adjustment period. |
