Abstract
In this study force sensing resistors were used to determine thepressure on the central area of each of the weight bearing pads of thefore and hind paws of dogs at the walk. Six adult normal healthy EnglishPointer dogs were used in this project. Pressure data were collected byaffixing a force sensing resistor to the central area of the groundcontact surface of each weight bearing paw pad of the right fore andhind limbs. Pressure signal data from stance phase during walking wereanalyzed. Within paw pads, the pressure graphs were consistent in formand magnitude. Within paws, there were significant pressure differencesamong pads on both fore and hind limbs. The coefficient of restitution,the embedding dimension, and the Lyapunov exponents were calculated. Theability to measure and analyze pressure on individual paw pads providesinsight into soft tissue stresses on the palmar/plantar surface of thepaw. Pressure at a wound site on the pads has a detrimental effect onwound healing and a better understanding these stresses will be ofbenefit when suturing and bandaging pad wounds. Such information isespecially important in athletic and working dogs, e.g. search andrescue dogs.
