How to Apply:
Remove product tube from package. Holding tube with notched end pointing up and away from the face and body, cut off the narrow end at the notches with scissors. While holding your dog with one hand, use the other to apply the solution. Invert the tube, and use the narrow end to part your dog's hair while gently squeezing to apply to the dog's skin. Hold the dog for a few seconds to give the solution time to be absorbed into the dog's coat. When finished, wrap the tube in paper and put into the trash.
Apply one tube as a stripe, starting high on the back of the dog's neck and ending directly in front of the shoulder blades.

Love the smell of it!
September 21, 2017
10 months ago
I was very surprised that this product has 4 applications, enough for the entire summer.
I purchased this product because it had active ingredients that would not only make my 14 year old dogs, smell good, but actually protected them from ticks and fleas. Recently moved to an area that are known for ticks and would not like to encounter them on my dogs. I purchased two boxes each, one for 7 lb. dog and one for 27 lb. dog. I hope they continue to do the job they were meant for.

Smells like nature and works great!!!
This "natural defense" works grrrreat!!!! It smells like pine trees and the dogs dont mind it at all. So far no fleas and ticks!!!! Thanks sentry!!

Works Great!!!
Yes, the smell can be overpowering BUT it Worked good. We have many stray cats in our neighborhood that had given fleas to our 2 dogs and because the cat stick around it has been so hard to get rid of the fleas. At first it did not seem like the Sentry Defense was working and the smell was strong, but after one week the fleas seems to be gone and have stayed gone. If you can deal with the strong smell for just a few days, I think you will be happy with the results!

Good alternative to expensive brands
Sentry Natural Defense works just as good as more expensive brands of flee and tick protection. Unlike other reviewers, who wrote that the smell of this product was bad, I did not have a problem with the scent. In fact, it smells like an orange cleaning product or maybe a little like feebreeze. Overall, this is a good product, it does what it claims, and the price is great!

I love this product. If my dog has one flea he goes crazy, and he hasn't had any since using this product. I have used it 3 times so far. The smell is strong but very pleasant, like a strong fragrant candle. I would recommend putting it on your dog in the morning because if he sleeps with you it is a little overwhelming because it is strong, not because it smells bad. I love the cedar and peppermint smell; it makes my house smell good, and you can't beat the price.

Agree - Odor TERRIBLE
I read the reviews about the odor and said -- that's only somebody's opinion. But, the price was so irresistible that I ordered a years worth. Put the first dose on yesterday morning and it was awful. Locked the dog out of the bedroom -- he ALWAYS sleeps with me. He was heartbroken. It calmed down a bit today but still stinky. Finally washed the dog to get it off.Please, a couple of people said they liked the odor. Each of us has our own opinions. But, don't over-do it and try one package before you jump in with both feet.

My Favorite
Great product. It seems to repel ticks and bugs, unlike other products which do nothing until the dog has been bitten.
June 25, 2012
Adjust dosage
I8 have had to adjust the dosage to 1/4 the amount, as the natural aroma takes over the room, house... I will keep trying for a correct dosage.

works awesome!!!!!!
I tried this about a month ago and it works awesome my dogs are always outside in the woods or the fields and they haven't had any ticks at all. i have tried other products but one of my dogs were allergic to it and had a skin reaction. Anyways i didnt like using poisons.Like most people say the smell is strong the first couple days but then it smells good after a little while.My dogs didnt mind it either one of my dogs actually loved the smell of it.

Used it last year and was very pleased how it worked, and love that it is natural
SIBBIE P on Apr 4, 2015
I can NOT recommend this product anymore since both of my dogs have since gotten fleas. This product did not help kill the fleas whatsoever, but in the company´s defense the fleas were extremely resistant to anything I tried. Had to move to the new advanced chemical treatments and practice much vigilance cleaning.

Will it wash off swimming and/or bathing?
A shopper on Apr 28, 2015
BEST ANSWER: I do not think so. Because though it is natural, it still is applied and goes into fat cells like the other toxic chemical applications. And after being on our dogs, I feel safe giving them a bath and having them still protected. I'd wait at least 24 hours after applying before bathing, or bathe before applying. We don't bathe more than once per month and these are applied monthly.
Is this applied to a single spot, where?
A shopper on Nov 19, 2014
BEST ANSWER: I normally apply from the base of the neck (near the shoulder area) to the base of her tail. I will occasionally find a tick crawling on her after a walk in the woods, but otherwise, have not had any trouble with fleas or ticks becoming attached. Does have a rather strong smell initially, which some people find offensive, but it disappears a lot within a couple of days.
Do you use one tube a week or one tube a month?
A shopper on Mar 26, 2017
BEST ANSWER: I use it once a month. It has a strong smell of cloves that eventually wears off. I prefer not to use strong chemicals on my fur babies so I prefer this. I have been using it for years. No fleas...knock on wood!
Is this product safe for pregnant dogs?
Cindy on Oct 18, 2016
BEST ANSWER: Not sure about pregnant dog's none of my babies are pregnant ( have 8 doxie's) but have one that has had bad reaction to most flea treatments and has no problem with this product. So will continue to use this, works very well.
How old is the youngest this can be used on can it be used on puppy's under 12 weeks old?
Riggs on Feb 4, 2018
BEST ANSWER: Hello! It would be best to consult with your veterinarian before use.
