Frontline Shield Flea & Tick Treatment for Extra Large Dogs, 81 - 120 lbs

Apply topically. Starting 2 days after application, this treatment can start killing fleas in 5 minutes and ticks in 1 hour.

How does FRONTLINE® Shield for Dogs work?

Once applied, FRONTLINE® Shield 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 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.

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

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 fleas in 12 hours before most fleas have time to lay eggs. The pyriproxyfen in FRONTLINE Shield prevents development of flea eggs and flea larvae, breaking the flea life cycle.

Why might I see fleas on my treated pet?

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 infestation. FRONTLINE® Shield will typically kill any new fleas jumping on your dog within 12 hours.

Why does it take so long to resolve a flea infestation in the home?

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 regular flea treatment, no new populations of fleas will be able to get established.

My dog doesn’t go outdoors much, do I still need to treat them for fleas?

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. You pets can still be exposed to fleas in your yard, especially in areas protected from the sun, like under bushes and in crawlspaces.

Do I need to treat my dog for fleas and ticks even in colder months?

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. Fleas also continue to develop indoors in homes thanks to the warmer indoor temperatures. Therefore, it’s important to keep protecting your pet throughout the year.

What happens if my dog gets wet straight after applying FRONTLINE® Shield for Dogs?

Once FRONTLINE® Shield on 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.
