FAQ

Learn More About Hartz From Our Team of Experts
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.

Trusted and used this brand for my dogs, within a week of using they both developed internal bleeding and liver damage ultimately leading to their death. This was at 2 separate times. First dog died, I didnt link it to the soap until I used it on my new dog and he developed the same symptoms of poisoning and passed. A horrible product that needs to be taken off shelves and a class action lawsuit be filed. DO NOT BUY.

Absolutely normal. Ive been using this for more than 12 years. Some animals may just be allergic to this but I have never had that issue. Thank god.

HARTZ KILLS

Hartz is a known product for killing animals that owners use their bathing and other products on. How do you trust a company that doesn’t even list the ingredients

Hartz is a known product for killing animals that owners use their bathing and other products on. How do you trust a company that doesn’t even list the ingredients on the bottle? and then says that the ingredients are “proprietary.” They are trying to hide the toxic ingredients that they use. I refuse to use this for my dogs and I recommend using another product.

Smells Wonderful!

I'm sure the fleas enjoyed the smell too, because they didn't die.

Flea and tick shampoo

This shampoo smells good. It worked to kill the fleas. The consistency was on the thinner side which makes it easy to distribute.
