About Hartz UltraGuard Topicals for Dogs


Why Choose a Flea & Tick Topical?
Hartz UltraGuard topicals provide monthly non-stop flea and tick protection. Just apply directly to your dog’s skin—they’re fast-acting and help prevent reinfestation for up to 30 days!
How Hartz Flea & Tick Topicals Work
Hartz UltraGuard topical formulations utilize your dog’s natural oil composition to spread their active ingredients across the skin. Once applied, the monthly formula moves across the skin and hair for full body protection.
How to Apply Hartz Flea & Tick Topicals
Step 1: Open the package and remove one tube.
Step 2: Break the seal by twisting the dispenser tip while pushing down.

Step 3: Position the dispensing tip on your dog’s back between the shoulder blades.
Step 4: Apply the topical directly to the skin, from the shoulders to the base of the tail.
