Application key benefits

Easy-to-apply topical solution – no hard-to-swallow pills

Easy Application – Step 1

Holding the tube upright and pointed away from you and your pet, remove the cap from the applicator tube. Turn the cap around, place it back on the tube and twist to break the seal.

Easy Application – Step 2

Evenly apply the entire contents of the tube along the top of the dog’s back, from the shoulder down to the base of the tail. The number of spots depends on the size and weight of the dog (please refer to the product label). At each spot, part the hair until the skin is visible. Place the tip of the tube on the skin and gently squeeze a portion of the solution on the skin.
