Hartz UltraGuard Pro Flea & Tick Topical Treatment for Large Dogs (61-150 lbs) - 3 Month Supply

For large dogs weighing 61 to 150 pounds, Hartz UltraGuard Pro is a monthly topical flea and tick treatment that kills fleas, deer ticks, and brown dog ticks on contact, and repels mosquitoes before they bite. It contains dual Insect Growth Regulators (IGRs) to prevent re-infestation and comes in a 3-dose pack for three months of protection. The formula spreads via natural skin oils for full-body coverage, and the easy-to-use Pro-Glide angled applicator with rounded edges simplifies application on both long and short-haired dogs.

How This Treatment Works

This topical solution is applied directly to the skin between the shoulder blades. Once applied, the active ingredients—Etofenprox, N-Octyl Bicycloheptene Dicarboximide, and Piperonyl Butoxide—spread across the dog's body through the natural oil layer on the skin and coat. This allows the treatment to reach from head to tail, providing full-body protection. The dual IGRs help break the flea life cycle by killing flea eggs and larvae, preventing re-infestation in your home and on your pet.

What Pests It Targets

Hartz UltraGuard Pro kills fleas, flea eggs, flea larvae, deer ticks, and brown dog ticks on contact. It also repels mosquitoes, reducing the risk of bites that can cause discomfort and transmit diseases. The formula is designed to be fast-acting, so pets get protection shortly after application.

Application and Protection Duration

Each single-dose tube provides one month of protection. The package contains three tubes, giving you a three-month supply. The patented Pro-Glide angled applicator is designed for easy, stress-free application even on dogs that are not used to topical treatments. The rounded edges of the applicator make it more comfortable and less intrusive. The formula dries quickly and does not rub off easily, so your dog can resume normal activity soon after treatment.

The active ingredients are Etofenprox, N-Octyl Bicycloheptene Dicarboximide, and Piperonyl Butoxide. This product is intended for use only on dogs or puppies that weigh 61 to 150 pounds and are at least 12 weeks old. Do not use on cats or kittens.
