Rated 3.5 out of 5 by 77 reviewers.
Rated 5 out of 5 by All Natural and it is 100% effective against fleas and ticks! I had previously purchased Sargeant's All Natural Flea and Tick and loved it. I bought enough to last me for our move out of state. When my supply started to get low, I looked high and low but could not locate the same product in state and in my former state. I contacted Sargeant's and they informed me it was now called Sentry. We checked the ingredients and sure enough it was the same product. Love, love, love that I do not have to put harmful chemicals on my beloved furry kid. The first few days it has a strong smell but after this period it settles down. More importantly, he has not had one tick and we have only spotted one flea. He is low to the ground and prior to using this medication he was a tick magnet. Couldn't be happier, cannot find this product in my local stores so I searched the web. Prices were the best at Chewy and the product arrived within a couple of days! Kudos on great customer service, price and product! December 4, 2016
Rated 2 out of 5 by Plenty K-9's to try this on I have 4 dogs that I used this medication on. Unfortunately it didn't work exact like I expected and didn't live up to my expectations as a dog owner and as a consumer. I did think it was working great up through the first couple of days. But after a full week had gone by. I began to realize that this product wasn't right for my family and our pets. When the week had elapsed, the fleas were as bad as they'd ever been. January 9, 2017
Rated 5 out of 5 by Good Product for the Price I bought this item for my grandson who can't afford Flea and Tick for his 2 dogs. I'm hoping it will keep the dogs protected for 6 months. December 16, 2016
Rated 1 out of 5 by Not effective Not happy with this product. Not effective, does not prevent from fleas. November 20, 2016
Rated 5 out of 5 by . I used this product on 7 dogs with good results. The smell was nice. November 16, 2016
Rated 1 out of 5 by Had bad reaction My blue heeler had a bad reaction from this product. I do like the smell but unfortunately won't work for us November 19, 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
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.
