BONE SPAVIN
—is an ossified enlargement on the outside of, and rather below, the centre of the hock, originating in a cartilaginous protrusion from the seat of articulation becoming progressively callous, and lastly a substance equally firm with the bone itself. They do not invariably constitute lameness upon their first appearance, but it soon follows a course of hard or regular work. Blistering first, and firing afterwards, was the practice of farriers of the old school, which it is not known has undergone any change with veterinarians of the new.
