Product details

Frontline Spot On for Dogs is effective against flea infestation for approximately two months and against tick infestation for up to one month, depending on the level of environmental challenge.

Within 24 hours of landing on your pet, fleas are killed and the treatment last for up to one month. Frontline Spot-On Dog can be used in puppies from 8 weeks of age and weighing over 2kg.

Key Benefits:

  • Elimination of fleas (Ctenocephalides spp.) and insecticidal efficacy against new infestations with adult fleas persists for 4 weeks.
  • Prevention of the multiplication of fleas by inhibiting the development of eggs (ovicidal activity), larvae and pupae (larvicidal activity) originating from eggs laid by adult fleas for 6 weeks after application.
  • Elimination of ticks (Ixodes ricinus, Dermacentor variabilis, Rhipicephalus sanguineus). The product has a persistent acaricidal efficacy for up to 2 weeks against ticks (based on experimental data).
  • Elimination of biting lice (Felicola subrostratus).
  • 48 hours after application pets can swim or be bathed as normal.

Can also be used as part of a treatment strategy for the control of Flea Allergy Dermatitis (FAD).

  • Frontline for dogs
    I have been using Frontline for many years and have always found it to be very effective. I treat my working Labradors between March and November, when they spend most of the time out on the moors. I have never found any fleas on them and although they do pick up ticks any that I miss are dead by the next day. Recommended for all dogs.

    Been using this for years and after trying another couple of flea and tick products still believe this to work best
