To make the pills come out easily, we suggest pills should be split into parts to feed, such as size of a good-sized vitamin tablet Usage instructions: insert a pill (better a medium-sized pill) at the tip of the pill popper. Or load the liquid medicines into the barrel. Place index and middle fingers under finger rings of pill popper. Open pet's mouth with one hand over top of head and muzzle.
