Epi-Pet Double Sided Brush is an essential tool in the performance of Epi-Pet's patent pending Three Step Application, Brush+Spray+Brush. One side of the brush head has stiff wire bristles that are spaced openly while the other side has firm but softer nylon bristles. The stiff open spaced wire bristles are extremely effective at exfoliating or removing dirt and flakes of dead skin. These wire bristles also work to increase the blood circulation near the surface of the skin so that the Epi-Pet All-Purpose Natural Treatment Spray can be absorbed into the skin more efficiently. Also, the wire bristles are excellent for untangling snarly and matted hair.
