golden retriever needs Sentry flea and tick repellentA class action lawsuit states that the essential oils present in Sentry Natural Defense flea and tick repellent are toxic to pets.

The Sentry class action lawsuit was filed by Ramona Penikila who says she purchased Sentry Natural Defense for her dog in August 2019 at a Petco in California. Allegedly, she relied on the advertisement that the product was safe for pets.

Penikila claims she read and followed the instruction for use of the product, and applied it to her dog. However, she says that after application, her dog suffered serious hair loss along with abnormal skin irritation and itching. The plaintiff states that she then scrubbed the area where the product was applied, and her dog eventually returned to normal.

According to the Sentry class action lawsuit, advertising that the product is safe for pets is misleading. The Sentry essential oils class action lawsuit says that Penikila was injured because of this false advertising in a number of ways, noting that her dog suffered physical harm from the product.

Additionally, Penikila was allegedly injured because she suffered financial harm. She says that had she known that the advertisement was misleading, she would not have purchased the product.

The flea and tick repellent class action lawsuit states that the Sentry repellent contains essential oils that are not safe for cats and dogs. 

Sentry repellent contains peppermint oil, cinnamon oil, lemongrass oil, clove oil, and thyme oil. Penikila says that these oils can be toxic if absorbed through the skin or ingested by pets.

Allegedly, symptoms of essential oil poisoning include “irritation to the skin, vomiting, muscles tremors, and other more serious complications that can lead to organ failure and death.”

To support her claim that essential oils are poisonous to pets, Penikila cites an article posted on the Veterinary Centers of America website, which advises pet owners to never apply concentrated essential oil to their pets, because even a small amount could be harmful. The article reportedly lists essential oils present in the Sentry product as among those harmful to pets.

Allegedly, the maker of Sentry repellent knew that essential oils were poisonous to pets, noting that the company claims its products are “Veterinarian Tested.” However, the class action states that the company does not explain that essential oils are not recommended by veterinarians.

    Bought this natural product as an alternative for my 18 year old senior dog, thinking it would be a safer alternative. Put it on and immediately he started to pant heavily and was very uncomfortable and distressed. Within two hours I scrubbed him down many times with dishwashing detergent and shaved the fur where we placed this product. Hoping we caught it before causing any damage. Our pup is still very lethargic and shaking. Very worried after reading all the reports in these comments. This is horrible. Please let me know if there’s something I can do to try to alleviate the symptoms and add me to the class action. Can’t understand why they would keep this product on the market. It is a crime!

    Bought sentry because the clerk at petco recommended it and my cat had a mini seizure only a few hours after application. He has lost fur in the spot it was applied. I only found out about all this after looking into it. I can’t believe someone even recommended this product and that it’s even on shelves with this many issues.

    My 2 1/2 yr old Maine Coon, Ole, was given a dose of Sentry Purrscriptions squeeze-on flea and tick medicine on his back before I left for work. When I came home, he was running and jumping all over the place and scratching with his hind legs. He had a bald, bleeding scab about 3 inches by 1 1/2 inches where the medicine was applied. How can they possibly be able to sell this? After calling vet emergency, I clipped his claws, washed the area with soap and water, and put bandages over his feet to prevent any further scratching. Try and do that by yourself to a 25 lb. scared cat. He was breathing heavy and still wouldn’t lay down for almost half a day. 4 days later, he still seems affected, but is getting better.
    Please add me to class action suit.

    Just used sentry on my sisters car. She bought it without reading all the reviews online. Cat now sits in one place, wheezing, hasn’t ate in days…. gave her a dose of Benadryl according to vet but no change, so we will be bringing her in. Terrible product. Would NEVER recommend to anyone.
