Frequently Asked Questions

How does FRONTLINE Shield 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.

Does FRONTLINE® Shield for Dogs repel mosquitoes?

A monthly application of FRONTLINE Shield for Dogs kills existing fleas and prevents new fleas from developing, kills ticks, and chewing lice, and repels mosquitos and stable flies. Preventing mosquito bites is essential, as infected mosquitoes can transmit diseases such as heartworm in dogs.

Can my dog get wet right after applying FRONTLINE Shield?

Your dog needs to be dry at the time FRONTLINE Shield for Dogs is applied and remain dry for 24 hours after application. 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.
