Function well

Works good

Good product

We have four 85+ pound dogs and have used "Frontline" for years as a summer preventative. -- We never have had a "flea problem," but have always taken steps to ensure our pets stay mite, flea, and tick-free. This product works just as well as Frontline, but at a MUCH MORE REASONABLE COST, especially considering the size and number of our dogs. The other comments here RE: "More fleas after using..." etc.: Your dog's environment must be treated too -- regardless of what product you use. Also, when a dog DOES have fleas, and is treated with topical flea prevention, the fleas do not instantly die; they begin migrating to the paws of the dog where the fur is not as thick and they escape or die while in route. THIS migration is a strange sensation to dogs, and they respond to "creepy-crawling," (migrating, not biting), fleas, mites, etc., by initially scratching, licking, and even biting their paws a little for the first couple of days. After that, everything returns to normal. PREVENTION: Groom your dog, bathe your dog, keep your yard well watered and maintained. If your property has fleas, treat it. THEN apply whatever flea prevention you like. Just keep in mind: They all have the same active ingredient. Nothing will do the maintenance work for you. Good Luck!

One of our dogs has a rash that seemed to pop up shortly after the application. Im not sure if its related or not. The dogs do live outside, so the rash could be from anything, but I will see what happens on the 2nd months application. Havent found ticks on the dogs though, and its tick season. Cant say whether it is good on fleas or not as we've not dealt with them.

Stopped the fleas fast.

Seems to work very good

We have used this brand for years. Seems to work really well.

Great price for a good product.

My dogs got fleas while they had this on, I had to go get the collars for them, they work.
