The safest and most effective tick protection - ticks fall off just from touching the fur

I brought my dog to West Virginia, and thank God for Advantix II — because I’ve been finding half-dead ticks every single day (no joke) in places where she sleeps or rests. At first, I was confused. I thought "repels ticks" meant it would work like bug spray does for mosquitoes, keeping them away completely. But after looking into the active ingredient, permethrin, I realized that in this case, “repel” means: once a tick touches the treated fur, it becomes so irritated or neurologically impaired that it can’t bite, can’t hang on, and eventually just falls off and dies.That’s still so much better than PetArmor, Frontline, or any of the oral preventatives (like Simparica or NexGard), which require the tick to bite the dog before it dies. No thanks. Every tick I’ve found so far had already dropped off my dog before it had a chance to bite her and feed — exactly what you want in a tick-heavy area.I’ve also tried Wondercide (cedar oil). It works okay for fleas, but it’s just not effective for ticks, especially not in the long term. Its protection wears off after 2–4 hours. I learned the hard way — my dog caught Lyme disease, developed joint pain and a limp. Thankfully, doxycycline helped and she’s okay now, but it required a full 28-day antibiotic course.I would never use oral flea/tick medications. Just ask around — you’ll hear plenty of stories about dogs having seizures after taking them. For me, that risk isn’t worth it.If you have a cat at home, unfortunately Advantix II may not be right for your household — permethrin is toxic to cats (especially when wet). But if you don’t have cats, I highly recommend this product to all dog owners. Tick-borne diseases are no joke. Fleas are annoying — I’ve had to go through the nightmare of clearing an infestation — but at least they just suck blood without causing life-threatening illness.Ticks, on the other hand, can transmit Lyme, Ehrlichia, Rocky Mountain spotted fever, and more. So if you live somewhere warm, humid, grassy, or deer-heavy — do your dog a favor and get Advantix II. It’s been a lifesaver for us.

Works great awesome I definitely suggested

Started having dogs when we first got married we have we had seven English mastiffs yeah it’s addicting and they had puppies and everything so anyways I’ve been using this on my dogs from year 2000 and I use them before that on my other dog so I’ve always used it really and I love it. I mean, I swear by it this stuff is great. My dogs do not get flea or I mean I have to put a spray on them to detail the mosquitoes, but don’t see my bugs biting them. It’s pricey, but it’s worth it. You don’t wanna have your dogs get Lyme disease or you know from ticks, I really suggest this.No bother my dog knock on wood you know in the other thing is I don’t use this year around. I only use it from spring until after fall. I don’t feel I really needed in the winter time. It’s too cold outside for anything to live so I’m up Northeast And I don’t seem to have any problem and they’re not using it as soon as spring hits that’s that boom they’re on it.

Excellent Preventative!!

Totally excellent protection when coupled with a flea and tick preventative pill from the vet! My pup is a rottweiler mix, 67 pounds....the pill that the vet gives her really upsets her stomach so they advised to just give her half of the pill and to grab some of this k9 advantix and use this especially during the summer months. I only use half of each dose (for xtra large dogs) monthly coupled with half of her prescription preventative...Viola!!! We found our perfect solution to her discomfort and those pesky little bugs around the house weighing on my anxiety! Doesnt seem to irritate her skin at all. Easy to apply, doesnt become too oily or caked with dirt. We apply it after a good bath with flea and tick shampoo and it lasts after the 2nd and 3rd bath as she needs to be bathed.

Will be buying again!

Since using this, I have noticed way less ticks than normal. We've put on a lot of miles shed hunting, going through the woods and tall grass. While I find a handful of ticks on myself afterwards, I'm lucky to find one on my dog.I've been using this on her now for 4-5 months and I have never noticed any irritation from it. It's super easy to apply! It is pricey but I truly believe you get what you pay for here.I used to use tick collars because I'm not a fan of the greasy mess this leaves on fur. Unfortunately tick collars just aren't as effective. So, we will stick with the greasy fur to avoid ticks from now on!

One happy puppy!

This is very easy to use with step by step instructions printed on the box. Ticks and fleas are no where to be found in the heart of tick country. My son’s skin has cleared up fast from the bites he once had. I will continue to buy for the future!
