Great for a 2nd line of defense.
This is identical to K9 Advantix II. This product works great for my dog, but then again my dog's skin doesn't have severe reactions to permethrin. Permethrin is extremely deadly when used incorrectly. For instance undiluted permethrin spray used on goats with direct skin contact will send a goat into nervous system failure within 2-4 minutes. They loose control over their bladder. Their back legs shutdown. The goat will continuously stretch out long and it's legs get wobbly and their steps get very uncoordinated. If the permethrin isn't removed from the goat's body with soap that has sulfates in it, in order to break down the molecule structure compounds of the permethrin, then the goat will go into seizures and die. If permethrin can do all of that to a goat, just imagine what it can do to your dog. If permethrin is used properly and dosed correctly it has proven to be very safe and effective, compared to many pesticides used on livestock and pets. Please, when testing any pesticide product on your pet, only test a small penny size area to start. Just like you don't slather your face in a new unknown facial cleanser or cream due to possible skin reactions, you don't go pouring pesticide products on your dog's skin if they have never been introduced to the product prior before. Common sense goes a long way. Personally, this product works wonders for my English Mastiff. This isn't a fix all product though. If your dog already has fleas or ticks they need removed with a few baths soaked in Dawn dish liquid original. This product will NOT remove or kill off a current infestation. I know what the product claims, but as a goat farmer who has actually worked with undiluted permethrin; which is the active ingredient in this product, there isn't nearly enough permethrin in this product to kill off a full blown tick of flea infestation. This product is a good deterrent and keeps pests from wanting to bite and start a infestation. If you apply this to your dog and get a odd reaction within the first 5 minutes, then you should react VERY quickly. Use a soap with sulfates in it, such as Dawn Dish liquid original. Use cold water also to stop the skin pours from opening up and enlarging, which would allow more of the pesticide residue into the blood stream. Scrub and wash the affected skin area, vigorously. Do not toss water on or dunk the affected area. By not scrubbing the pesticide residue away from the skin and minimizing the effect of it soaking in deeper past the dermal layer, you're only wasting precious time. Scrub, scrub, scrub. I've used permethrin for a long time as a goat farmer. Around and in my barns. In our milking area and on our milking stands. In chicken coops and duck houses. In our buck barn and around common areas in the pasture. Also use it in our basement to keep out hundreds of pests. This product is a good product, but never let your guard down. Always be looking for ticks, fleas, mites, lice, etc. Do your best to minimize exposure, period. This product is for 2nd line of defense. This product is NOT a cure all fix all, 1st line of defense kinda product. But then again neither are the real expensive Rx script chewable tablets either. Been there, done that.

So far so good!
Great so far! Got this for my 11 week old chihuahuas. I adopted them and they came to me with fleas!! I had been pulling fleas off of them for the first 3 days, multiple times a day. I ordered this in the 6 month supply so I can have a 3 month supply for both of them. It’s been 24 hours since applying the treatment, and NO FLEAS!! Not one!! There’s no strong chemical smell, no grease, no side effects! It even came with stickers for your calendar to remind you to apply the next dose! Great instructions, hoping it continues to hold up well!

not a single flea insight
worked very well for both of my dogs however, I think one may have had an allergic reaction, but I’m not entirely sure if it was the weather change or the medication will be trying and updating my review next month

Ok but what's with the flakes?
I received this item and it came as expected my disappointment is because it leaves white flakes done the lone where you place the medication. It seems to work for now but I dont like the flakes. Overall its a good value.

WORKS GOOD!! BEST SPOT ON ESP FOR PRICE!!
Works better than any other spot on!! But does not last entire mo!! U get 2-3 wks of flea control I use Adams flea shampoo last WK of this!? But don't apply the shampoo same line as spot on!? And while pill will work all yr with 1 time! 1 pill! Only half ur dogs or less!? This will have to be used at least 3 MO in a row to get the fleas dn!! But get soon as I c 1 flea for best results best control!? And remember it needs to make skin contact to work well!? So take a trimmer or dog sheers shave a small line rt dn the back if they have long hair esp!? Ya the dog will look funny with reverse Mohawk but it will make the product work! If u don't ur just applying it basically to the hair!? Which won't let it work or work well!? Just saying.... If I c ANYYY fleas this season I will def order use this again!! RT now theirs none and I'm using Adams Flea Shampoo for Dogs every single bath!? Helps keep fleas away to begin with and makes dog smell great for WK!? But DO NOT OVER DO OR MIX FLEA CONTROLS IT CAN OD KILL OR HURT DOG!! USE COMMON SENSE!!

SIDE EFFECTS
PLEASE BE AWARE OF POSSIBLE SIDE EFFECTS!! I am sure that this product works for some dogs, unfortunately that was not the case with my pup. He is a 6 year old boxer/pit mix and I applied it to him the day it came in the mail as a preventative with the weather becoming warmer. There was some slight itching immediately, and continued through the night and following day but TWO days later, he broke out in hives all over. Extremely itchy and unable to get himself to relax. I feel like I have noticed some behavioral changes, acting almost skiddish. Since the hives did not occur until two days later, washing off the product did not do much. He had gotten two baths, one being oatmeal, and some Benadryl. Hoping that the hives go away soon because he is just miserable. I even bought the 6 month supply and am now unable to return for money back.

Fleas control and many others
Very very great flea protection. Just follow the directions and they’re protected for a month. But I have two dogs so they don’t last as long due to that. But very good. Didn’t make them sick and just make sure they don’t rub it off bf drying.
