Rated 3 out of 5 by from Flea medicine review When I bought this product I had high hopes but when I put it on my dogs, it only worked for a week and they have fleas once again. I do not know what happened but it just isn't working any more. They are scratching at the fleas as if they didn't have medicine for them. I'm sorry but I cannot recommend this product.

Rated 5 out of 5 by from Works For My Dachshunds! I have four Miniature Dachshunds and live in North Georgia, aka Flea Country! I absolutely love Sentry FiproGuard! My dogs are extremely sensitive to flea products, even frontline makes them sick or break out in hives, but this never had bothered me and when I use it I never find a flea on them! I love this product and recommend it to all of my friends!

Rated 1 out of 5 by from Doesn't work I have 6 chihuahuas that are constantly scratching because of fleas. I was hoping this would work but they are scratching themselves raw from the fleas. Guess I better look for something else that WORKS !

Rated 5 out of 5 by from GREAT PRODUCT I have been using this product for over a year now. It is VERY comparable to their competitors but without the large price tag. I have a German Sheppard/Chow mix, 2 pugs and a Chihuahua. It works great on all as long as you get the right dosage size.

Rated 1 out of 5 by from This product is not satisfactory. I have never used this flea and tick med before ordering this time from Chewy. It is not as good as what I am used to getting. My two dachshunds scratch all the time. The product is missing some ingredient that it should have. Guess I am stuck with it. May cost me vet bills in fleas and ticks.
