This formula also kills fleas which may cause Flea Allergy Dermatitis and flea bite anemia. That’s why K9 Advantix II Large Dog topical, spot-on formula makes application simple - going on in seconds. It's easier than a flea collar and there are no hard-to-swallow pills. You’ll also love that K9 Advantix II is fragrance-free and waterproof after 24 hours of application. Check the product label for information on application and potential side effects.

Directions for Use
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.

These shelves are great. They felt light in my hands but I can assure you they do hold their weight. As you can see I have lots of crystals on mine. They are easy to assemble and look nice. I recommend them.
