This module will discuss the intrinsic and extrinsic elements that effect health and performance in animals. This module will also look at a wide variety of activities that dogs take part in that may result in sports injuries and diseases. These activities include dog agility, fly ball, gun dogs, sheep dogs, racing greyhounds and pet dogs. A veterinary physiotherapist needs to know what injuries are likely to occur during different activities, what predisposes an animal to these injuries and conditions and what treatments and therapies they could receive both from a vet and other para-professionals. Some of the conditions studied in this module will include joint conditions in the dog such as elbow and hip dysplasia and cruciate ligament rupture; spinal conditions including disk disease. It also includes discussion of up to date diagnostic procedures, veterinary and complementary therapies including surgical techniques, rehabilitation methods and prevention. The use of drugs and nutraceuticals as a therapeutics and as performance enhancers will be analysed.
