K9 AdvantixII XL Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention | Dogs Over 55 lbs. | 1-Mo Supply

I’ve been using K9 Advantix II on my dog for a few months now, and it really works! It starts killing fleas quickly and keeps protecting against ticks and mosquitoes for a full month. Super easy to apply, and I’ve had zero issues with skin irritation or side effects.The smell is a bit strong at first, but it fades within a day. Just be careful if you have cats, as it’s not safe for them. Overall, it’s worth the price for peace of mind and a happy, itch-free pup.Highly recommend

This product works. Easy to apply and seems to get rid of pests quickly. It lasts a long time too . After the first application I did not see any more fleas. I did mot have any trouble with my dogs getting irritated skin or any abdominal issues either like with other products I have used. I have both XL dogs and a small one. All had the same result.

Works effectively, reasonably priced, bought for fleas. Felt it worked quickly. Will buy again.

So this stuff kills and prevents it ALL! That's the good part! The bad is... it kills and prevents it all... SO if I continually put this on my dog... onto his skin.. down his back... and your skin is the largest organ that absorbs it... This cannot be good for my dog long term. I used to do this when flea/tick season was in high gear in my area (google flea/tick season for your state) and then stop in the winter months. Then I slowly just tapered off and stopped using this all together. It works and works well. My dog has no issue with it at all. The months I had put this on him, no flea or tick or mosquito in sight. It does spread into his long fur and takes a bit to dry/absorb like a day or two so that can be messy. You can't really pet him down his back at that time. You're not supposed to bathe them before or right after application. He never had any skin rashes or negative side effects from it. That being said, I personally decided to stop using it monthly. I don't take him to tick heavy areas like woods and if I do, I always, always, always do a thorough tick check on him. It's tedious, he has long, thick hair (golden retriever) but worth it 1000%. Of all the things in life I will mess around with, ticks and the diseases they carry (esp. lyme) are not one of them. Fleas, I will treat with capstar if need be but not really any fleas get on him. That being said I still purchase and keep this stuff around, WHY? because it kills everything. It's amazing to have on hand for emergencies, mainly like when a tick ATTACHES to him and I'm so scared if I pull it off wrong, it's head will still be in his skin (this is bad because it can still transmit diseases this way). SO when that happens, I get this out, put a generous DROP onto the tick and let it do it's magic. Let all those chemicals and pesticides and whatever kill that TICK at least paralyze it so it cannot bite and hold onto my dog's skin anymore. This takes, well I give it 30 seconds but usually a min or so to be safe. Then, I do what they say to do, grab the tick with tweezers and gently twist and off it comes head and all. I then, because I hate them so much (the only thing worse and scarier than spiders are ticks) burn them with a lighter. I show them NO mercy. Anyways, this product works, it doesn't have any bad effects on my dog, BUT I don't use it regularly anymore because I think it can be a lot on my dog's body/immune system. I DO keep it around though for emergencies that can and do crop up. That's part of life and owning a dog. So would I repurchase, YES, would I recommend? Yes. Just not all the time, but to have on hand. I'm not saying eliminate all chemicals and never use them, I just reduce WHEN I can.

This is the only flea and tick medicine I will use on my dogs. Works very well yet doesn't affect animals with allergies and problem prone skin. I have seen no negative reactions.

Dealing with a flea problem and this was recommended. It is definitely a walking flea killer. Our dog is 80lbs. After I apply this I see dead fleas on her bed and the ones still on her are moving at a fraction of the speed. We reapplied after 3 weeks due to her weight and this is for dogs 55lbs. Cannot let the fleas get a moment of rest. This is our first issue with fleas after a lifetime of having pets and it is a nightmare so I empathize with those going through it. I vacuum daily in the main bedroom. No pets on the bed for our sanity to have one space in the house that is for sure 100% flea free. Yard was sprayed and bought Nyguard to spray in the house. We do everything natural so it has been sad to turn to chemicals but when you become desperate you cave to what works best. I've tried essential oils and not sure how much that deters fleas. We also have a small dog and a cat. Pest guy says squirrels are main carriers for fleas so that is all we can figure out for how they got here. Or the cat that does wander at night. Also weekly baths on the dogs. The cat got a bath but he is black and I have yet to see a flea although he is always scratching. Also using homeopathy remedy so look that up. Good luck!

This stuff really works to keep fleas and takes away

After reading reviews, I was super hopeful this would work. We live in a wooded area with many animals around, and even though my dogs are in a fenced yard, we do have a flea problem. I should also mention they are inside dogs and only go out to do their business. We used this product on all 4 dogs, and they still had a little bit of a flea problem. It's not as bad as before, but still noticeable.
