Description

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 over 55 lbs. to use K9 Advantix Extra Large Dog. Use as directed by label. Do not use on cats.

Doesn't last the month for my dog
Not a bad review. Doesn't work for my dog. I've tried before and just purchased again to see if it really was the product. Works for 2 weeks and then my dog is back to itchy scratchy again. It always worked on my previous dog just fine.

It doesn't last a month.. first 2 weeks are good.. Third week smoke scratching.. third week you are waiting for the date you can apply again.. But...Frontline is the same.. it was my go to.. then it started working like this. Then advantix became my go to.. They are both about the same... Except advantix is much cheaper. ... show more

Not effective
Waste of money, used on both my dogs and had no effect my dogs kept scratching and getting bit, switched to another brand and bites and scratching stopped almost immediately
