This variant comes in a red pack and contains 250 mg imidacloprid in a 2.5 ml pipette, delivering targeted action against fleas through contact—so they don’t need to bite your dog to be affected.

The easy-to-apply topical solution spreads across the skin and coat to kill adult fleas and larval stages, helping break the flea lifecycle. With consistent monthly use, it supports ongoing protection and helps maintain your dog’s comfort and skin health.
