Rated 5 out of 5 by from Great features and price I just bought this product a month ago and I am so happy with results! It is just like buying the generic at the pharmacy and saving 50% or more on your medicine. Sentry Firbo Guard MAX works great, and keeps my dog from contracting parasites on his skin. My dog is a rescue who was severally neglected and developed a strong allergic reaction to fleas from prolonged exposure to fleas. I use this product in combination with Sentry's PRO flea and tick shampoo to create an iron shield around my pup's skin. The poor guy has sensitive skin from all those years of neglect, but this combination of flea preventatives keeps him protected without irritating his skin. I highly recommend this product if your dog has a history with fleas.

Rated 5 out of 5 by from Fiproguard Spray We've never had a flea issue, and I live in the south. Recently, instant infestation. Not sure it was all the rain we got early spring or if we've had a lot of stray traffic in the wee hours, but my poor girl was miserable. We tried everything. Some would work for a few days, some didn't work at all. I found Sentry Firproguard spray at Tractor Supply. Figured because it was cheaper it would be yet another failed attempt to get this under control. WRONG. Wow... fleas couldn't evacuate quick enough! Almost instant relief for my girl! Will not be without this in my dog supplies ever again!

Rated 5 out of 5 by from A forever customer! I had used frontline plus on my pixie (dog) for years. Until it just stopped working! Within a few days she was miserable. So I went in tractor supply saw sentry fiproguard plus and decided to try it . So very happy that I did. Thank you Sentry for putting a better product out their for our beloved pets that is a lot cheaper than frontline and works better! I have now told all my dog owner friends and they too only use sentry plus. And also have had only great experiences from changing over from frontline! A forever customer. JenA

Rated 5 out of 5 by from great product at reasonable price I purchased this after our daughter's dog picked up fleas at another house. We had tried homemade products and natural products without luck. This worked great and helped eliminate the fleas.

Rated 5 out of 5 by from Sentry saved the day....never using another type! I had bought my rescue schnauzer Advantix II and 4 days later I found 2 ticks on him. I panicked! I ran to the Veterinarian and they told me Sentry was the Mercedes of Flea and tick killer...AND IT IS!!! Haven't had a tick on him since buying your product. . THANKS SENTRY! !

Rated 5 out of 5 by from Great for my little dog! I have used this for two years now. My chihuahua goes in the woods hiking in Maine. I haven't found any ticks since we started using Sentry! And no fleas either!!!!

Rated 1 out of 5 by from Ticks gone, fleas not so much I bought this product after using Advantix II for several months. Advantix killed fleas but not ticks, this product seems to be the opposite. After almost 2 weeks since I applied it, both of my dogs are still covered in fleas.
