Active ingredients

The effectiveness of a fleas shampoo will depend on the active ingredient it contains.

Some flea shampoos for dogs will use pyrethrins or (S)-Methoprene. These are known as insect growth regulators and are often used in different flea treatments. The best thing you can do is talk to your vet and ask for advice on how to get rid of fleas.
