How does Flea Shampoo Work?
Types of flea shampoos vary, and not all will be appropriate for your pet.
Many flea and tick shampoos only help remove the fleas from your pet’s fur. They simply wash them out and away. This is obviously a good thing — although it won’t do much to otherwise interrupt the flea life cycle.
The most effective flea shampoos contain insecticides such as pyrethrins which cause the fleas’ nervous systems to shut down, killing the adult fleas and flea larvae.
Killing the fleas at all life cycle stages like this means it is much less likely that they will keep coming back. Using these medicated shampoos regularly when you bath your dog is an inexpensive way to win the war against fleas.

Shampoo for fleas often includes a conditioner to keep your pup’s fur shiny and soft, and their skin healthy.
Flea Shampoo vs Other Flea Treatments
Flea and tick shampoo for dogs is a good way of keeping parasites under control but are not necessarily a sure fix to a flea infestation problem as they may only work for a short time.
Although flea shampoo can be used as a standalone treatment, they really work best when combined with a topical ‘spot on’ type medication.
These types of medication are very effective as they release an active ingredients that kill the fleas from the pores of the skin itself, and this can keep working to repel and kill fleas for several weeks.
If you’re using shampoo as the only flea treatment on your dog, you may want to consider repeating the shampooing process every couple of weeks to keep the fleas at bay.

If you’re wondering what’s best for your dog, remember you can always consult your vet. Topical spot on treatments combined with a regular dosing of the best flea shampoo will put your dog on the right path for now though.
