Frequently Asked Questions

How does FRONTLINE® Shield for Dogs work?

Once applied, FRONTLINE® Shield for Dogs is stored in the sebaceous glands in your dog’s skin and spreads over the whole-body surface with their natural oils protecting your dog for 30 days. Fleas and ticks are killed through contact with your dog’s skin and coat, so they do not need to bite to be killed.

Why is it important to tackle flea eggs as well as fleas?

Even if you have treated your dog for fleas, some fleas may lay eggs before dying, therefore it is important to tackle flea eggs. FRONTLINE Shield for Dogs kills fleas before most fleas have time to lay eggs. The pyriproxyfen in FRONTLINE Shield for Dogs prevents development of flea eggs and flea larvae, breaking the flea life cycle.

Can my dog get wet right after applying FRONTLINE Shield for Dogs?

Once FRONTLINE Shield for Dogs has been applied, it is recommended to keep your dog out of the rain and away from water for the next 24 hours. If they do come into contact with water before 24 hours, the efficacy of the treatment may be impaired, and reapplication may be warranted. If this is the case, please contact your veterinarian for advice.
