A fellow breeder sent me this and I found it really a helpful tool to understand gaits in dogs with normal and abnormal movement. Enjoy!

This is a learning module to teach how to identify patterns of movement
associated with healthy gait, HD and cranial cruciate ligament rupture. It
uses optical motion capture data. A 5-year old greyhound is used for the
healthy example.
