II Medium Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention | Dogs 11-20 lbs. | 6-Mo Supply

Works great to get rid of fleas. It also keeps the fleas away when used monthly. There isn’t a strong odor. The product fully absorbs in about 2 days so others due is mildly greasy for a day. Good value .

I have used this for years. You apply to their back. It is easy to use and not messy. My dogs have not gotten fleas or any other bites. I will continue to use. It works well and lasts for the month if not longer. The dogs do not notice it on them. Do not scratch or try to lick it. Great for the price. I have not noticed any side effects.

I have used these for years and the last 3 months supply has been a disappointment they are not killing the fleas at all. My babies still have fleas crawling all over them after application. I will no loner be buying this product.

Small flea problem outbreak. Quickly eradicated the flea issue on my pet.

K9 Advantix II keeps fleas, ticks, and mosquitoes far away from my small dogs. Easy to apply, vet-recommended, and works fast — no more itchy, grumpy pups. Peace of mind for me, tail wags for them. Highly recommend if you want a pest-free pooch.

We have fought fleas on all fronts in our hot and muggy rural area. Frontline and the generic version- useless. Sprayed the land, treated our home, sprayed our dog with an additional temporary spray. This is the first time we've ever had such problems. Dog was constantly scratching, visible fleas and flea dirt. Flea comb simply full of mature fleas and flea dirt. Two vet visits in which we were told the next step was a yearly and expensive treatment. Thankfully, found this on Google as vet recommended. Bought a dose here. It arrived yesterday and we immediately applied as directed to 15 lb dog. He was fine upon application. No major problems afterwards but did began to claw himself aggressively and nip at his paws. Found those relatively minor results on the carton safety data and saw no reason to be overly concerned. I did give him the dose of antihistamine as prescribed by our vet. I think the fleas were 'abandoning ship'! He became drowsy within about 40 minutes settled down and slept soundly all night. No raw spots or other problems today but he looks like a newer, improved dog today. He is basically white. Today there were no visible fleas or flea dirt. Yes! So glad we found this product, all I will buy again! Great customer support because I called the # on the product box today just to check his reaction. They were great.

We'll moved out to the country from the city and my dog never had fleas in the city. But out here in the country, it seemed the fleas love him. I bought this stuff on December the 12th applied it immediately. today is December 27th if you see the pictures that I've posted with this review I've already picked multiple fleas off my poor dog And there's tons more flea dirt all over places. Disappointed that this name brand flea medication hasn't even lasted its 30 days. I mean, yes, it worked for a brief period like two weeks, and then now the fleas are back. So I'm gonna go ahead and reapply it, but I'm not purchasing this brand again. I'm gonna try something else. im very disappointed and my poor dog is just as itchy as before the 1st application.

Great product
