Despite their effectiveness, using essential oils for fleas on dogs alone is not enough to get rid of fleas, you should also consider using other flea and tick prevention products for dogs.

A dog with a healthy coat and a robust immune system is a bad host for fleas, so if your dog is infested with these parasites, you may need to take an in-depth look into the overall health of your pooch.

Start with food; you may be feeding your dog something that he is allergic to, which in result, weakens the immune system and expose your dog to be the perfect host for fleas.

The best way to eliminate fleas is to prevent them in the first place, for example, using flea combs and vacuuming your house can be very useful to stop the spread of fleas.
