It is small enough and easily controlled to work between the toes. The 8 Tooth Cdisc is the way to go if trimming large herds of goats. There are also three abrasive discs designed to remove hoof material, and these are also used between the toes. The Gold Fine Grit Disc is used on smaller goats with less to remove or for a first time trim. The Blue Medium Grit Disc is used on goats that have small to standard size hooves or regularly maintained hooves that do not require a lot of work to bring them back to confirmation. The Blue Medium Grit Disc is also great when treating a foundered goat. The Silver Coarse Grit Disc is best suited for medium to large goat breeds like Boer Goats or goats with rock hard hooves. Choice of trimming disc will be dependent on the environment and current condition of the goat’s hooves. It’s best to try each one to see what works for you. The Hoof Boss Trimmer is designed to help ease the wrist and hand pain associated with using hand shears to trim and is easily operated with one hand, leaving the other hand to hold down that flying leg. The Hoof Boss Mobile has a powerful motor that provides a fast, smooth trimming experience.
