## Description

ADVECTA Ultra Flea and Tick Protection for Large Dogs (21-55 lbs) contains the same active ingredients as K9 Advantix II for Dogs*. This waterproof, fast-acting flea topical for dogs kills and repels fleas, tick, and mosquitoes. Advecta dog tick and flea treatment breaks the flea life cycle by killing flea eggs, flea larvae, and chewing lice for up to 30 days. This topical is great to use during flea season when pet owners spend the most time at the dog park and on outdoor adventures. As an alternative to oral flea pills, use this topical alongside a flea comb on fur to keep pets flea-free. *ADVECTA Ultra for Dogs is not manufactured or distributed by Bayer Healthcare LLC, the makers of K9 Advantix II. K9 Advantix II is a registered trademark of Bayer Healthcare LLC.

Review: 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.
Review: Dogs have never had a tick since starting this medicine! - Great and effective product for a great price.

### ⭐⭐⭐⭐ not a single flea insight
*by S***Y on February 6, 2026*
