Fleas and ticks must feed before they are killed, so the spread of tick-borne disease cannot be ruled out. There is no data for puppies under 8 weeks old or dogs under 2kg. Ask your vet first. Full details are in the NOAH Compendium datasheet.

Parasite control
Fleas, ticks and worms: why you often need to treat for both
Fleas can carry tapeworm larvae. Dogs and cats become infected with the tapeworm Dipylidium caninum when they swallow an infected flea or chewing louse. ESCCAP guidance says tapeworm control includes controlling fleas and lice. More in our fleas and ticks advice, including how long flea treatment takes to work, how to check your dog for fleas and how to check your dog for ticks.
Frontline flea and tick products do not treat worms, and Frontline Wormer does not treat fleas. Ask your vet or pharmacist which combination suits your pet. Other flea and worm brands are on our Stronghold and NexGard pages.
