The Johnsons Dog Flea & Tick Collar is a water-resistant dog collar designed to kill fleas and ticks and prevent further re-infestation for up to 4 months.
The active ingredient in the Johnsons Flea Collar takes effect almost immediately, spreading throughout your dog's entire coat within a matter of days.
Fitting the one-size Johnsons Dog Flea Collar is a simple matter of sliding the end of the collar though the buckle, leaving enough space to insert 2 fingers between the collar and neck, before cutting off any excess.
The Johnsons Dog Flea Collar is suitable for dogs and puppies over 12 weeks of age. Not suitable for lactating bitches, or dogs who have been treated with another insecticide.
