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.

Directions: Use only on dogs. DO NOT USE ON CATS or other animals. Do not apply to dogs weighing less than 4 lbs. Remove applicator tube from the package. Use scissors and peel down foil. Hold applicator tube in an upright position. Pull cap off tube. Turn cap around and place other end of cap back on tube. Twist cap to break seal, then remove cap from tube. The dog should be standing for easy application. Evenly apply entire contents of the tube along the top of the dog's back, from the shoulder down to the base of the tail. The number of spots depends on the size and weight of your dog (please refer to the product label). At each spot, part the hair until skin is visible. Place the tip of the tube on the skin and gently squeeze to expel a portion of the solution on the skin. Do not apply an excessive amount of solution at any one spot that could cause some of the solution to run off the side of the dog. Do not get this product in your dog’s eyes, or allow your dog to ingest this product.

  • 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.
