This is caused by hard or irritating substances making their way in
between the claws of the foot, causing inflammation, and sometimes
ulceration, in the parts. The pasterns swell, and the animal becomes
lame.
The foot should be thoroughly washed, and all foreign substances
removed. A pledget of tow, saturated with tar and sprinkled with
powdered sulphate of copper, should be inserted between the claws. This
usually requires but one or two applications.
