Sentry Fiproguard Flea & Tick Dogs 23-44 lbs, Fipronil, 3-Month | Ideal for Medium Dogs 23-44 lbs; Kills Fleas, Ticks & Chewing Lice for 30 Days; 8 weeks+; Vet-Quality OTC Formula

I’ve been using Sentry Fiproguard for my large dog for several months now, and I couldn't be happier with the results! This flea and tick prevention product works incredibly well. It’s easy to apply, and I love how quickly it starts working to keep those pests away. My dog has never had any issues with fleas or ticks since using it, and it’s been a huge relief knowing he’s protected. The product comes in convenient, pre-measured doses for each month, so there’s no mess or guesswork. I also appreciate that it’s designed specifically for large dogs like mine (89-132 pounds), ensuring that he gets the right amount of protection. The best part? It doesn’t irritate his skin like some other treatments I’ve tried, and he doesn’t even seem to notice when I apply it. Highly recommend this flea and tick treatment if you want something effective, affordable, and easy to use. It’s been a game-changer for my dog’s health and comfort!

A large old mutt, an Aussie, a YorkiePoo and a Choodle. I actually only used this product for 2 months last Summer. I had no fleas or ticks over that period. I quit applying it too early in the fall and found a few ticks after that. This year I will start as soon as I see bugs and stop only when fully into winter. I take my dogs walking on trails frequently, so they gave it a good test. My primary concern is with ticks as these can be life threatening to a dog, and I did not find one tick while using it. I check my dogs frequently for these blood suckers. I did not have a flea problem either, even after I quit using it in the fall. Perhaps fleas do not come out like ticks in late fall warm spells. I found ticks even in February a couple years ago during a very mild Midwestern winter. Regarding the bad reviews, go figure. My understanding is that this is a preventative, if you have a preexisting problem on the dog or in the home getting that under control can be a more arduous task. However people trash Frontline as well. Frontline is incredibly more expensive. The active ingredient is identical, although I know that does not always guarantee products to work identically. However this worked for my 4 dogs, I certainly would have found ticks on them had it not worked, after about 50 or so trail hikes, including at the large dog park that we go to. Regarding fleas, I had none, but I had none to start with. In my experience all other topical flea/tick treatments have been ineffective, only the active ingredient in this product has been effective. I will wait until the end of this year before I firmly decided that brand is great stuff, if not as good as Frontline, close enough. My new Chiwennie adds a 5th test subject to the mix. However I do feel pretty strongly that it is based on my last year's experience. I realize that Frontline also has a product that kills eggs as well, but feel that if you don't let the problem get started, that is probably not super consequential, not enough to justify the dramatically increased cost of that product.

As described.

I bought this along with K-9 Advantiix II and this cheaper, less well known brand actually lasted a month while I found a few fleas after the two week mark of applying Advantiix. It's extremely hard finding a good and lasting flea, tick, and mosquito protection for my dogs. Capstar worked immediately but is only made for that. I does not work for longer than 2-3 days. So it's honestly a complete waste of money unless you can afford to waste like that. But probably not an option for owner with multiple dogs. I've run the gamut of natural remedies and they fail miserably while making my dogs smell like some old shoe water juice or something. Very pleased I found an affordable and effective treatment.

We have a wooded yard and used to struggle with fleas and ticks on our small dog. Since using Sentry Fiproguard for the past year, we haven’t had any issues! It’s easy to apply, comes with clear instructions and pre-measured doses. I use auto-ship so we never miss a month. Great price and very effective—highly recommend!

The first time I bought this product for my two small Chihuahuas I brought two 6 months, one box for each of my small dogs for 3 months. The first box worked very well the first three months on both dogs, I was impressed. When I opened the second box the tubs where all sucked in but I could squeeze out the medicine for the next 3 months but my dogs did not started showing any signs of relief from scratching fleas for the next 3 months from the second box of fleas medicine did not work. I stored this flea medicine in my desk in the house that has AC and Heat and could not understand why the second box all the tubs were sucked in and did not relieve my dogs from Asian. The next 6 month I reorder 2 more boxes 3 months on tub for each of my dogs the second time because the first order one box did work very well. Another note: before I put flea medicine on my dogs (who are not outside animals) I gave them both flea baths once a month each time. The next day I applied this product. I found this product again did not work my dog started again scratching the first month. The second order 2/ 6 months has not worked. I am now convinced this product does not work and my dogs had to suffer with fleas. Fool me once shame on me, fool me twice shame on you.
