Step 1: Trim the Toes
Use nippers to reduce toe length. Do this in several increments, inspecting the end of the toe after each cut to determine if another cut can be done safely. The ideal toe length is about 50 mm. With some sows, there may be one overgrown toe on the foot, and one very short (stunted) toe. In these cases, you may not be able to reduce the long toe to match the length of the short toe.
Step 2: Straighten the Wall
Toe overgrowth often curves or buckles the dorsal wall, making it concave. Use the angle grinder to straighten the wall by removing excess wall horn below the area where buckling occurs. The wall should be straight from the coronary band to the bearing surface.
Step 3: Balance the Sole and Heel
Use the grinder to reduce the sole depth. The objective is to have a flat and level sole area across both claws for functional weight bearing of the foot. It is common for the outside (lateral) claw to be more overgrown than the inside (medial) claw, so the lateral claw will need more sole horn removed. The medial claw often only needs flattening, with minimal sole horn removal. If the heel is overgrown, remove soft tissue with the grinder or hoof knife. The outside heel is often more overgrown than the inside heel, but with care these can be made even (except in cases where the inside heel is small and underdeveloped). The heel should not be trimmed all the way flat to match the sole, as it acts as a ‘first impact’ shock absorber when the sow walks.
Step 4: Trim Dew Claws
Overgrown dew claws are prone to injury and can interfere with normal locomotion of the sow. An ideal dew claw horn should be approximately 20 mm long. Use the nippers to reduce dew claw length. Do this in increments until a satisfactory length is obtained. Use the angle grinder to round off the end of dew claws. Good Foot Example Use a sharp hoof knife to remove loose and undermined horn to the point where reattachment of the horn with the underlying tissues becomes evident. This procedure should be done with care as to avoid damage resulting in hemorrhage and damage to the underlying corium.
Caution: Do not draw blood from the claw when trimming. If you draw blood, you have trimmed too aggressively and have penetrated the corium. It is better to leave a little extra horn than to remove too much.

Our goal is to provide a safe haven for abandoned or unwanted pot belly pigs and provide them with the medical attention they need, as well as the love and attention they deserve.
We will participate in fundraising to provide veterinary treatment, spay/neuter, food and shelter; as well as foster responsible pot belly pig ownership through education and adoption.
