K9 Advantix kills and repels fleas, ticks, mosquitoes, biting flies, and lice. Simpler than a flea collar and hard-to-swallow pills, this topical formula works within 12 hours of initial application to stop existing flea infestations on dogs and prevent new ones by killing adult fleas on contact before they lay new eggs or bite your dog. K9 Advantix offers fast relief at an excellent value, so you and your dog can get back to the things you love most. Your dog should be at least 7 weeks old and weigh 21-55 lbs. to use K9 Advantix Large Dog. Use as directed by label. Do not use on cats.

I've used this for the past 3 years on my dogs and I've never had a problem with either one of them. They're both healthy, well taken care of. + This flea control is a great value for the money

I put this on all 4 of my dogs. They all had no adverse reaction. The smell wasn't bad and didn't linger and so far I haven't seen fleas or itching this summer which is surprising. Don't forget to spray the outside of your house and treat your lawn for insects. The fleas come from outside, so treating the outside of your house is a must, especially where your dogs frequent outside.

Didn't work very well on my dogs

Use this monthly on my dog since we have woods in our backyard and the deer traverse daily. One tick is all you need to find and you'll be running for a preventative. This goes on easily, follow the directions, it doesn't seem to irritate her skin and she is pure white, short hair. I'm very happy with the results. Easy to apply and I have it as a subscription delivery every 2 months thru Amazon so I'm not without.

My poor babies caught fleas and immediately started them on treatment with flea and tick collars and meds. They work immediately and pleased with the outcome. My dogs didn’t have side effects and starting giving them relief. Value for money is better than getting this same product at my local Walmart. Application is easy but my dogs don’t sit still for long so I have to try and apply it fast.

This works really great. Our dogs kept having an issue with fleas and our vet told us it is a huge problem in our area. He recommended a treatment similar to this (an ointment applied between the shoulder blades) that was prescription only. It cost three times what we paid for this and didn't work at all. The only thing is, we have to apply it every two to three weeks in order to maintain its effectiveness but I think that is because of where we live, not that the product itself doesn't work. We have tried other brands but this one definitely works the best.
