Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Will this still work if you bathe the dog after? Or go swimming?
Answer by ChewyJun 19, 2017
After allowing the treatment to be absorbed for 24 hours, you will be able to bathe your dog, or allow them to go swimming.

How does it work is it absorbed into the skin
Answer by ChewyMay 01, 2019
This product is dispersed over the pet's body by the natural oils on their skin and attaches to the hair follicle. This process can take up to 24 hours.

I have a dog that's 32 lbs. And one who's 61 lbs. Would it be okay to apply this to the 31 lb dog instead of having to buy two separate applications?
Answer by ChewySep 17, 2018
This treatment is formulated for specific weight ranges. It is important to use this treatment as directed, for the weight listed. Otherwise, it is possible to overdose or under-dose your pet.

I see it says monthly but if severe fleas can it be used more than monthly
Answer by ChewySep 19, 2017
The treatment is only to be used as directed, 1 tube per month. The measurements go by weight and may harm your dog if used incorrectly.

Sentry user

I’ve been using Sentry for my dog since she was 4 months old for daycare and have no complaints. I used to purchase it at a local pet store that only sells it in packs of 3 months. I recently realized Chewy sells it in 6 months packs, so I’m definitely switching to ordering it from Chewy (along with my treat orders). Much more convenient & economical.

Use this brand on all 13 animals

I have 10 cats and 3 dogs. I purchased this brand in various weights and after 24 hours none of my animals have fleas.

Sentry Fiproguard

I tried this topical flea treatment as the one I usually buy is out of stock and it had the exact same ingredients. Works great and the cost is less. As stated in other reviews, this product does leave a white residue on your pup’s fur for a few days. Not a deal breaker for me - it actually reminds me not to touch the area. Will purchase again.

Product Review from previous purchase

I didn’t receive this when recently ordered, however, I’ve used this before and it works great. It has the same active ingredient as other brand named treatments.

Sentry is a good bet.

I never used this before but I will use it again. It does what it's supposed to do. My only complaint is that it leaves a white residue at application site. Still a good product.

Works fine.

Dogs don't have any fleas or ticks, nor heartworm or parasites. But if you have a prize winning black lab, their fur turns white for a couple days- until it spreads for coverage..
