II XL Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention | Dogs Over 55 lbs. | 1-Mo Supply

After trying several different flea and tick treatments over the years, K9 Advantix has consistently been one of the most effective options for my dog. Application is quick and straightforward, and within a short time I noticed a significant reduction in fleas. Living in an area where ticks are common, it’s reassuring to know my dog has reliable protection during walks, hikes, and time spent outdoors. One thing I appreciate is that it doesn’t leave a heavy, greasy residue once it’s had time to dry, and my dog hasn’t shown any signs of irritation after application. Following the recommended dosing schedule has kept the protection consistent month after month. The peace of mind alone makes it worth the investment. Keeping fleas and ticks under control is much easier than dealing with an infestation, and this product has helped do exactly that. Based on my experience, K9 Advantix is a dependable choice for pet owners looking for effective, easy-to-use flea and tick protection.

UPDATE I don’t know what y’all all your people take your dogs to the vets instead of showing them online here that they can’t walk. The fur is falling out of the bleeding. That’s ridiculous. Take your dog to the friggin neck. Let the vet determine the cause exactly and then if it’s in clause because of this then Put a negative and state the fact that you took him to a vet and the vet did test and it was the closet because I’ve been using this product for 25 years on my dogs back then and my new dogs now my dogs I had 16 years ago dogs I had 10 years ago dogs I had 13 years ago my 16 1/2 year old cocker spaniel has had this from the day he could actually have this And I have never had a problem with that on any of my dogs especially him you know it got rid of the fleas and I noticed a few texts very easy to get off compared when I didn’t use it like if I skipped a couple of months and they had a dick and I was like oh my God and then I would try to get it off and it was a hassle. I mean, it did not pull up. Come out whatever And so I put them back on this every month originally and if they get a tick and I see it. I just need tweezers and it just pops right off no eggs inside nothing no problem with the weather did not cause any of my dogs ever itch or lose hair so I think you people have an undergoing problem with your dog that you did not address Prior to use this. Yes, I’m gonna blame you. Yes I’m blaming all you that people that has undermining problems with their dog and you don’t take them to the vet and you add this product on top of them. Yes, it probably will do something like that. SO I REPEAT, TAKE YOUR DOG TO THE GD VETERINARIAN PROFESSIONAL LET THE PROFESSIONAL DO THEIR WORK !!!! Oh, I also have one dog right now. I have three of them English mastiff and I have one of them that sits at my back gate in the dirt never has fleas never has sticks never has any. He lays in the dirt 185 pound and his head I can look it out right now his head is in it. His whole body lengthwise is in it and I swear he digs holes just you know it makes it cool.. and there’s a picture of him laying at the fence in the dirt. He loves it. I check them every day. Nobody has fleas. Nobody has anything so you people are doing something wrong. I’m gonna blame all of you. They have a problem and I’ll say it again again again they have underlining problem TAKE THEM TO THE VET VETERINARIAN HAVE THE VET, VETERINARIAN, TECHNICIAN, AND DOCTOR EXAMINE THE DOG TAKE SKIN GRAPHS WHATEVER THE BEST HAS TO DO. DON’T BLAME THE PRODUCT UNLESS YOU DID THAT AND IF YOU DID IT AND THEN DOCTOR RUNS TEXT AND SAID YES, IT WAS CAUSED BY THAT PRODUCT. WELL HENCE THERE YOU GO AND IT’S THE PRODUCT FAULT BUT A 99.999% IT’S NOT THE PRODUCT. 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.

My dog is a Great Pyrenees at 100lbs. I use one of these per month as per the directions. Never knew if it worked until today. Found a handful of ticks I picked off in the parking lot after some grass on my dog, then one more 30 minutes later when I got home on her inner thigh that was half curled up and unresponsive. Hours later even after a thorough tick check I find what looks like dirt on her tail area, picking it up with a glove to see it was a deer tick completely dead and unresponsive. No ticks had ever bitten her at all. Fantastic product! Saves my dog, me, and anyone else in my household - they don’t just fall off they just die. Thank you!

Soon as I applied to my dogs AFTER FOLLOWING THE DIRECTIONS ON THE BACK mosquitoes definitely ignored my dog and cane straight towards me🤣 But definitely recommend bathing your fur babies and applying the medicine when they are completely dried. DEFINITELY ONE OF THE BEST TREATMENTS OUT THERE!!!!

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.

I've been using K9 Advantix (I and II), and I've never had to worry about ticks, fleas or mosquitos, and I live out in the woods in a state that has these critters *everywhere*. My dogs walk all around in the fenced off area of ~4 acres, which I keep mowed to 3.5 inches and only a few trees in the main backyard but a .5 acre cedar grove in the front of the house. Cedar keeps the climbing bugs at bay well enough, but walking the fence line in the back and around the 100 yd x 50 yd pond and I have to check for ticks on me when I get in. The dogs will have a couple on them, but they never get the chance to dig in, so leaving them outside a lot of the day and night doesn't concern me. When they're inside, wherever they sit or lay, they're leaving an extremely small bit of this stuff on the material that also kills the crawling critters. The pond, naturally has mosquitos, but they don't hardly land on the dogs...unfortunately they DO land on me. As I said, I've used this stuff for decades on my dogs and because of it they're not uncomfortable from biting insects and the mosquitos pretty much leave them alone or die after lighting on them and don't infect them with heartworms. Also, this is like water, so when putting it on the dogs you need to put it in several spots on their back for it to work best. Because it's a water-type stuff, no more messy, gunky oil-based junk to get all over your hands or places they lie or collect dust/dirt/etc. Overall this can't be beat since it covers pretty much any critters that would love to make a home on your dog.

I’ve been using K9 Advantix II on my two pups, Percey and Piper, and I absolutely love it. They are both big dogs, and this treatment has done a wonderful job keeping fleas and ticks away. One of the things I appreciate most is the peace of mind it gives me. We love our nightly movie time with the dogs snuggled up in bed, and knowing they’re protected from fleas and ticks makes those cozy evenings even more comfortable. The application is simple, and I’ve had great results with it. No scratching, no unwanted pests, and two happy pups! If you’re looking for reliable flea and tick protection for larger dogs, I highly recommend K9 Advantix II.

Gave this to my dogs and it seemed to work at first but after a week I still was noticing some fleas on my dog.

No es el producto de la foto ni de la descripción. Es el Advantix normal, el de la caja azul, nada de k9 ni versión 2.. es contra 4 tipos de insectos y no contra 8 .. Lo compré por qué supuestamente era la versión ii Me siento engañado, no lo devolví por qué me iba de viaje y necesitaba echarle algo ya, si no lo habría devuelto.

Vino tarde y y no en la caja original si que traía instrucciones, pero además tarde
