Rated 3.6 out of 5 by 71 reviewers.
Rated 5 out of 5 by Works great! It is very strong smelling at first -the smell fades, but I can tell you fleas and ticks don't want anything to do with my dog! And in the summer they're both BAD around here (mosquitos too) October 18, 2016
Rated 1 out of 5 by ATTRACTS Fleas Paco didnt have any fleas and now theyre EVERYWHERE..other bugs too. October 15, 2016
Rated 3 out of 5 by horrible smell! i am all for natural flea repellents, but wowie! this one really really really smells! i read the reviews and should of paid more attention when i used it. it is very very strong and i can only imagine how the dog felt. the cats stayed away so i assume the fleas did too! i had to put a t shirt on her at night so i could breathe. the next day i rinsed her off so we all could breathe a bit easier. not sure i want to try the other 2 doses. i might have to do a bit of research and see if there is anything i can mix it with to tone down the scent.

Rated 1 out of 5 by THat smell This product had the STRONGEST smell! It was super intense and you could smell it all throughout the house. I would be able to put up with it but it didn't get rid of the fleas at all :( October 1, 2016
Rated 5 out of 5 by Great Alternative to Nasty Chemicals! My little wire haired Jack Russell/ dachshund mix kept on getting fleas this summer. My husband and I were giving her flea baths once or twice a week but even though the chemicals were harsh, it didn't really seem to be doing very much to help her. She was so uncomfortable day and night. I bought this product and my hubby and I put it between her shoulders (open a window because the essential oils are powerful! The smell does fade as the serum dries - just be patient). Within a couple days those persistent bugs were gone and her skin had calmed down. Now she's laying on my lap sleeping happily instead of scratching and biting! We definitely recommend this! August 9, 2016
Rated 5 out of 5 by Great Product with less health concerns! I spend a lot of time with my pets. They watch TV with me and sometimes sneak next to me to sleep, so having a natural product that not only works, but I feel is safer for them and me, is great! I read reviews and was aware that the product is stronger smelling due to natural elements, but for only one day and the results are more than worth it! No reactions, like to the other over the counter products have caused some of my rescue pets either! I feel like the fleas and ticks are really bad this year, so I felt I had to re-apply right at or before 30 days. Glad I found this product! August 10, 2016
Rated 3 out of 5 by The Jury is still out..... I've been researching all natural flea and tick control for my 4 dogs and decided to try Natural Defense. I checked and none of the oils they use are bad or toxic to dogs but I still haven't made up my mind on it. I put a small drop on each dog to make sure they didn't have any reactions to it (which they didn't) and then sat back and waited to see how long it took for the really, really strong (almost overpowering but not unpleasant) smell of the natural oils to come down to a more bearable level. It took about 2 days and then it was just a light scent on their fur. Knowing how sensitive dogs noses are it made me wonder how the scent was impacting them and if it was causing them any nasal discomfort or headaches when first applied. If it was almost overpowering for me, what was it like for my dogs? The reviews I've read are good and it is much less expensive than Frontline and has the added benefit of being all natural but I think I'll do a little more homework before I make the switch. So the jury is still out on this one.... June 17, 2014
