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.

    I just saw this article and I wish I had seen it months ago before giving my Shadow puppy (he was going to be 2yrs old) a bath with this. We knew he had been poisoned but never did I think about the shampoo because why would a company make something for animals that could kill them? He was dead within 4 days of using this and he was on the way to the vet when he died. At first he just became sluggish which was not normal. We called the vet when he just wouldn’t eat anymore… he was still drinking though and since he wasn’t eating the plain food that you give when they have an upset stomach.. plus he started vomiting clear liquid the vet told us to bring him in the next day. He had an appointment for 1pm but didn’t make it. We actually were in route to take him in earlier then his appointment when he stopped breathing. This after two bouts of bloody diarrhea in less then a 12 hour period. Everything pointed to poisoning but I never thought the shampoo could be the culprit until I saw this and now it makes complete sense. Shame on sentry and any other company that makes something that has the potential to do harm like this. Shadow is buried in a corner of my garden so that he’s always near us. He was the goofiest and most fun loving dog ever who we swear was part kangaroo!!

If we lefty her There for 3 days and then had surgery done it would cost about5 thousand dollars and she still might not have made it. Thanks a lot.Senry.

    I wish I had read this yesterday. Used Sentry Flea and Tick on our 2.5 year old border collie mix. She started scratching non-stop. By the time we could get her into a shower, she had scratched off her fur in a few spots and has a terrible red rash. We gave her 50 mg of benadryl last night and again this morning and she’s still itching. Our vet says we may need steroid.

  6. Jannette Johnson says:

    I have 4 dogs and 2 cats and the squeeze on tubes I have used for several years. I have never had a problem. The smell is strong at first, so I put it on in the morning. I would rather use this then some kind of medication .

  7. Alicia Thomas says:

    We used the Flea and Tick Shampoo on our Dog and he started losing his hair and scratches constantly. Horrible scabs popped up on his body and in between his toes

  8. Anna VanderLaan says:

    Yes please add me on. I put the topical oil on him yesterday and today he was pulling tufts of hair out for had two large scabs on his nape. I just lathered his neck in dawn soap and washed him up. Both our two cats lost hair from this but my cat Pepe had the worse reaction with scabs etc. if it isn’t looking better by tomorrow morning I am bringing him to the vet because reading these other replies has me worried. Please do something to stop sentry from selling their products.
