Aristopet Frontline Spray is a topical flea and tick treatment for dogs and cats, applied by spraying directly onto the coat. It treats existing flea infestations and controls ticks — including paralysis ticks — as well as biting lice. Because it can be used from two days of age, it suits very young puppies and kittens where spot-ons and tablets are not yet an option.

The active ingredient fipronil sits in the oils of the skin and coat, killing fleas and ticks on contact rather than needing the parasite to bite. Coverage depends on saturating the coat evenly, so long-haired animals need a more thorough application than short-haired ones. It is also useful in multi-pet households where a single product across dogs and cats simplifies the routine.

The spray format is chosen for young or small animals, for pets that dislike being handled around the shoulder blades for a spot-on, and for owners who want visible confirmation the whole coat has been treated rather than a single pipette dose.
