The cause of lameness in some animals can be frustratingly difficult to pinpoint. Careful attention to a detailed history, observing the animal in relaxed surroundings, and observation of gait over different terrains (flat ground, gradients, steps etc) can all add vital detail. In addition, we will often request video clips of what the individual is doing in its own home, as fear and excitement can often mask subtle discomfort.
Thorough clinical examination is always essential, and sometimes is all that is required to make a diagnosis.
Very often history, observation and clinical examination will provide a very high index of suspicion of certain lameness problems, but further investigation is required.
