1. How does FRONTLINE® PLUS for Dogs work?

FRONTLINE® PLUS for Dogs contains the active ingredients fipronil and (S)-methoprene. The
dual action protects your dog against fleas and ticks.
FRONTLINE® PLUS for Dogs spreads from the single point of applidogion, rapidly covering the
entire dog and localizing in the hair, on the surface of the skin and in the sebaceous glands.
These glands act as a reservoir, continuously replenishing FRONTLINE® PLUS for Dogs onto
the skin and hair coat, so it keeps working even if the dog gets wet. Fleas and ticks are killed
quickly after coming into contact with a treated dog. Fleas and ticks do not need to bite in
order to die.
FRONTLINE® PLUS for Dogs also has the additional ingredient (S)-methoprene. This ingredient
is an insect growth regulator (IGR) which prevents all flea stages (eggs, larvae, and pupae)
from developing.

2. How often do I need to use FRONTLINE® PLUS for Dogs?

One dose (pipette) of FRONTLINE® PLUS for Dogs should be applied once per month to
protect against fleas and ticks. Year-round application is essential for pets in many parts of
the country.

3. Do I need to use other flea & tick treatments while using FRONTLINE® PLUS for Dogs?

No, FRONTLINE® PLUS for Dogs is an effective treatment against fleas and ticks that works
for a full month. If applied correctly and on a regular monthly basis, you do not need to use
any other treatments while using FRONTLINE® PLUS for Dogs.

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

Yes, although the likelihood of your dog being affected by fleas decreases in the winter
months, climates can vary and result in mild winters, favoring the survival of fleas outdoors
for much longer. Fleas can also continue to develop indoors in homes thanks to warmer
temperatures. Ticks can also be a problem year-round with some species of ticks attempting
to acquire a host when temperatures are just above freezing. Therefore, it’s important to
keep protecting your dog throughout the year.

11. What are the signs of fleas on my dog?

Apart from visually seeing fleas on your dog or in your home, other signs that your dog might
have fleas include increased itching, scratching, licking, nibbling and over-grooming which
can lead to damaged hairs or patches of hair loss. You may also see small dark red or black
specks on your dog’s skin, bedding or on furniture.

12. How do dogs pick up fleas?

Dogs pick up fleas from anywhere untreated dogs have been – indoors or outdoors. Fleas on
an untreated dog (or other animal host) can lay many eggs. Each female flea can lay up to 50
eggs per day. These eggs fall off into the environment, and over a period of weeks to months,
these eggs develop into new adult fleas ready to jump onto your dog.

13. What is the best way to remove a flea infestation in my home?

Flea infestations are unpleasant for you and your dog, and can take three months or more to
resolve, so be patient. Follow these steps to help resolve the problem:
1. Ensure all pets in your home are treated with an appropriate product, such as
FRONTLINE® PLUS for Dogs on dogs and FRONTLINE® PLUS for Cats on cats, at the
recommended intervals for at least three consecutive months.
2. Vacuum more often than usual – ideally daily – and focus on places your dog spends a
lot of time, for example, carpets, the floor and furniture.
3. Regularly wash your dog's bedding in hot water.
4. Ensure your dog has access to all the same parts of the home that they usually do.
Fleas present in those areas will be killed when they hop onto your treated dog.
5. In some cases, it may be helpful to contact a pest control specialist.

14. Where can I find the expiration date for FRONTLINE® PLUS for Dogs and how long
