Frontline Shield Flea & Tick Treatment for Small Dogs, 11 - 20 lbs, 3 doses (3-Month Protection)

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

FRONTLINE® Shield for Dogs should be used monthly to protect against fleas, ticks, and chewing lice, and repel mosquitos and stable flies. Monthly, year-round application is essential for dogs in many parts of the country for continuous flea and tick protection.

No, do not use on cats, rabbits, or any animals other than dogs. ONLY use products on the pet species that they have been specifically developed and licensed for, as severe reactions, including death, could result. FRONTLINE® Shield for Dogs is specifically formulated for and can only be used on dogs.

Once FRONTLINE® Shield for Dogs has been applied, it is recommended to keep your pet 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.

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

You are likely seeing NEW fleas on your pet, which are jumping on your pet as it moves through infested areas in and around your home. Moreover, if you are fighting a home infestation, it is highly likely that you will see fleas on your pet for 3 months or more as it can take this long to get rid of the existing life stages in the environment.

Depending on temperature and humidity, flea development from egg to adult can vary from less than two weeks (in summer) to well over 6 months (in winter). Existing pupal fleas in their cocoons are protected and need to develop and emerge as new fleas before they can be killed. Once all pets in the household receive an appropriate flea and tick product, no new populations of fleas will be able to get established.

Yes, even indoor-only pets can become exposed to fleas. Adult fleas can hitch a ride on your clothing, get into your home, and then on your dog. Even if your dog only goes outside in your fenced-in backyard, that fence won’t keep out wildlife that can carry fleas. Your pets can still be exposed to fleas in your yard, especially in areas protected from the sun, like under bushes and in crawlspaces.

Yes. Although the likelihood of your pets being affected by fleas decreases in the winter months, they can still pose a threat to your pet, and ticks are actually more active in cooler weather! Fleas also continue to develop indoors thanks to the warmer indoor temperatures. Therefore, it’s important to keep protecting your pet throughout the year.
