I've been using this, with good results, for quite a while. The most recent treatment failed to eliminate fleas from my dogs. I don't know if I got a bad batch, if the formula has changed, or if the fleas have become resistant but my dogs were treated on February 1st and again on March 2nd, and they are still infested with fleas on March 11.

I used this on an Australian Shepherd and an Australian Cattle Dog/ Border Collie mix who both had fleas. It didn't kill any fleas so I put another dose on 2 days later and it still didn't work. I then bought a Seresto flea collar and put it on one dog. Within 24 hours almost every flea was dead so I'm buying another Seresto collar and trowing this PetAction junk away.

I have 7 dogs, small to large, I've bought 3 different sizes of this and am massively disappointed. I've dosed all the dogs twice and now have infested dogs and house. Poor product. Like the guy said, "Don't waste your money, because it is NOT as good as Frontline Plus, it's like using water to kill fleas-USELESS.

My dog was infested with fleas. I gave him a shower and killed literally thousands of fleas.. I felt terrible for ignoring the problem, a week later was infested again. I used other product that didn't work, then I gave this product a try. Thank God I did. Just after 4 days I checked my dog and surprise, only found literally one sick flea didn't even try to jump. He seems so happy and relieved. I don't know if it will last a month but even if it doesn't I could give him a shower to keep infestation under control until next dosis if fleas returned. But so far is like a miracle. Thank God I found this product. Dog extremely happy and he takes good naps now.

We bought this because it was a main item at Sam's Club but it has been a negative for us. Our dog, 35 pound Wheaton Terrier starts chewing on his paws and scratching at his ears after we put it on him. Plus it leaves an oily feel to his hair. I wrote the company and NO RESPONSE OR REPLY OR HELP! That is why I am writing this now!

This was great much better valie than big brands that actually worked and they give 8 months work but why why why change it?! It smells horrible like rotten tuna, causing my dog to itch and lick which he never had a problem with and it leaves his nice white coat woth a large yellow greasy stain for the whole month im so disappointed in this. Gonna to find somthing else after 10+ yrs of buying this from sams

Exact same ingredients as Frontline Plus and has kept both of my Dogs free and clear of both

Has zero effectiveness. Waste of money. Don’t recommend.

Product works great and much cheaper than the name brand

We have been using this for years on our German Shepherds. Works great!
