Johnsons Dog Flea & Tick Collar

Johnson's Flea and Tick Collar for Dogs is a water-resistant collar that will kill fleas and ticks and prevent further re-infestation for up to 4 months. Flea kill begins almost immediately, but it may take several days for the active ingredient to spread throughout the entire coat. 

The collar will fit most dogs. If fitted to a fully grown dog, allow enough space for 2 fingers to be inserted between the collar and neck. For a growing dog, remember to loosen the collar as the dog gets bigger.
