If you Pitbull suffers from interdigital cyst like our did use Epsom salt and baby powder (corn starch). Soak their paws for a minute or two then dry it. Apply baby powder in between their toes and underneath their paw. The baby powder will absorb any moisture. Moisture between their toes is our enemy. Within days you will see major improvement. Do the epsom salt in the mornings and powder their feet during the day.
