Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

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.

Monthly Flea & Tick Protection

Pest Protection

Hartz UltraGuard dog topicals help kill and prevent fleas and ticks for up to 30 days, offering full-body protection.

Fast-Acting

Once applied, UltraGuard topicals start killing fleas in as little as 15 minutes.

Waterproof

UltraGuard offers full waterproof protection for 48 hours after application, so it keeps working even if your dog gets wet.

Pro-Glide Applicator

Hartz UltraGuard PRO Topical has a specially angled applicator for easy, mess-free application.

This flea and tick medicine works. I've bought many products recently in an attempt to keep my pup flea free and after many dollars spent, nothing was working effectively
