  1. Hello,
    I am currently having problems with local cities using herbicides and pesticides and causing acute toxicology symptoms and now a second dog has been diagnosed with squamous cell carcinoma. I have contact
    Earth Justice
    and have been trying to find an attorney. May I ask if you have any attorneys you know of who will take a dog case? No one wants to take on Monsanto and the few I have seen are only taking people cases.
    Thank you for your time. I know this is a very time consuming process. I have spent over $50,000.00 in vet bills and countless hours on the care of my dogs and now trying to put a stop to this. I have been dealing with it for almost 10 years now.

    Have a nice day and I will share this with others I know.

  2. I put this product on my cat earlier tonight. Then I decided to look at reviews because it looked very greasy and he was starting to scratch the area a lot. Once I saw all the reviews I immediately washed it off with dog shampoo because its the only thing in the house. All the greasy substance is gone now and the area smells like the shampoo. Is there anything else I need to do to make sure he is OK? Please respond ASAP!

  3. I think our cat was poisoned by Hartz UltraGuard (for ticks and fleas). We applied it in the AM and that night he was paralyzed, frothing, and has been steadily declining. We have used various tick medicines for many years with no issues. The ER doctor concluded toxic poisoning. What I would like to know is, how can Hartz be held legally and ethically accountable? How is a product still sold to consumers that is KNOWN to be lethal or injury-inducing? Can one sue Hartz, and is there any known success with this avenue??

    1. My cat died after giving it hurts I’m trying to figure out how to sue this damn company you can’t get through to anybody in two days he was dead

  4. I have a dog for eight years and put the flea drop on her neck and within 5 days she done died she suffered so much she only had half pint of blood left in her and her lugs filled up all from flea medicine.. I have read so many stories since this has happened I can’t believe they still have this on the shelves I will never get my Lola Mae back and I pray that y’all never have to go thru what I did with her…

  5. Hi there,

    just letting you know that your “photos” are not loading properly on your page. I really wanted to show the adverse effects of using these poisons on pets. Please let me know if I am doing something wrong as I try to open the pics or is it something on your end?

    We are launching a new ALL NATURAL cedar wood pet collar, please check us out and tell us what you like or don’t like….PLEASE we are about to be seen nationwide on major TV stations and could really use the support of groups like yours to expose the dangers of the poisons people are putting on pets AND THEMSELVES!

    1. I would like to get one to try here in dog is a service dog as.i am disabled so after this issue with the dog shampoo I will only be using natural things..cant afford to.lose her she keeps me alive

  6. I need help! Please and fast. I sprayed Hartz home flea spray all over the areas of our basement floor and after reading about the horror stories, I need to remove it? How can I do that safely? What do I use to wash it off, just water or what? This is really urgent, please and thank you!

  7. Applied the Sentry Purrscriptions late Sunday 11/12/17 on two indoor family cats. Monday, both started vomiting and by Tuesday they were rushed to Emergency Vet. Both were kept overnight on IV fluids and received treatment. The only common denominator was the flea medication treatment.

    One cat has rallied back but the other has been back to the vet and had to be put on IV fluids again for the day. It is one week later and he is still not acting right and it seems like his mouth is painful and I am concerned that he licked the medication off his fur. The neck area had a burn like reaction and it appears we will be taking back to the vet today for another check.

    I have been in contact with Sargent’s and reported all reactions and medical care up to date. For both cats it is close to $3,000 that we would not have incurred if not for their product.

    I don’t understand how a product can be sold through PetSmart that can literally kill a cat with use. I will continue to research to find out what I am able to do to bring this to the consumer’s attention and also seek reimbursement for the cost of medical care.

    In trying to do proper care for my cats, I have done more harm than good. To say I feel like I made a bad decision is putting it mildly.

    Any feedback is appreciated.

    Thank You,

  8. Has anyone got any responses when reporting to the following or others? If those responses were helpful, please comment and maybe they will get added to things recommended by HartzVictims.

    If pet owners complain to the product manufacturers and don’t get satisfactory answers, can they then complain to the Better Business Bureaus, BBB, that the manufacturers belong to? It takes a little bit of research to find the BBBs but might be worth it. I know for example that Hartz Mountain Canada belongs to at least one BBB. Accepted complaints then stay on the websites until resolved.

    It’s a good idea to have copies of invoices showing veterinary treatment and photos of the injuries as well as product that was used and its packaging.

    Find Google ratings for the manufacturers and post your reviews and complaints for others to see. I don’t see any complaints about flea and tick products on the Hartz Mountain Canada review!

    The ASPCA maintains a list of toxic plants and substances. If you’ve applied the product as recommended on the packaging and your pet has an adverse reaction, try reporting to them too, as long as they don’t require money for it.

    Ask your veterinarian about making adverse reaction reports. Ask if there’s reporting they should make to their state or provincial association and any other associations too. Vets may not be keen to suggest it if it means extra paperwork for them but you may have the right to insist, maybe even get a copy and confirmation that reports were submitted.

    For cat owners, they might also try reporting adverse reactions to the AAFP. The American Association of Feline Practicioners offers extra certifications for training and continuing education to veterinarians in North America as well as provides guides to cat owners,

    Do the same with the ICC, (formerly FAB), and the International Society of Feline Medicine (ISFM),
    – While some of the above sites have some warnings about permethrin toxicity, they think it’s only caused by accidentally applying products to cats that were meant for dogs.

    The ICC have a campaign where they want to require that OTC retailers to get verbal confirmation from purchasers that products will be used on the correct species.

    Reporting adverse events to associations, like reactions, harm and deaths, when products are being used as directed, may help raise awareness of this issue.

    [PLEASE note: I don’t endorse all of the cat care and feeding info from above sites. Neither would our AAFP cat vet or cat rescues. Please contact cat rescues for non commercial info NOT sponsored or provided by pet food or product manufacturers. That’s often where less informed veterinarians get their information too. This also helps prevent many issues, reduce vet bills and help with optimum pet health because that’s something they want for their cats and dogs too. Links to rescue groups can be found on and

    – Noncommercial site has warnings about some commonly used veterinary medications that are causing issues with cats and dogs. This site is recommended by many rescue groups for its info on feeding cats. Our cat vet prints out pages from it for clients.]

    Please reply if you’ve had results from reporting or suggestions on other places to report that aren’t already recommended.

  9. Why does the EPA say on it’s website that permethrin [pyrethroids] “are low in toxicity to mammals and are practically nontoxic to birds. However, pyrethroids are toxic to fish and to bees”?

    Permethrin is listed as toxic to cats in concentrations as little as 0.1 percent on the AAFP website:

    “Toxicity [in cats] occurs as a result of an insufficient glucuronide conjugation of the permethrin by the feline liver, resulting in high levels of the permethrin. This is further complicated by the fact that canine marketed permethrin products typically contain 45-60% permethrin while safe feline marketed products contain less than 0.1%. These products are absorbed through the skin and tend to concentrate in nervous tissue, resulting in signs ranging from restlessness and hypersalivation, to muscle spasms, seizures, and death.”

  11. My dog is losing her hair thanks to your oatmeal flea and tick shampoo. After reviewing similar issues as well as fatalities due to this product. Why is is still on the market? I will be contacting every agency, and filing a lawsuit. This product should be discontinued. It is not healthy for ANY animal.

  12. We brought this to wash our girl ,🤬 and her hair starting falling out I took me to out vet to find it here was nothing they could do to save her 😢 she passed away

  13. Wow I can’t believe this is the same kind that my dog uses since she was a baby until now she has her shot took her to the vet nothing was wrong with her as the months gone by this is the reason why she has no hair looking like she’s got cancer or with some type of sickness now I know why her hair’s falling off cuz I use the same kind of soap for her how crazy😳😲😬😮 😢


  15. How do i get to be a part of the lawsuit? My cat died about a yr ago from a hartz flea collar. Necropsy results confirmed he died from pesticide poisoning n that was the only thing pesticide related he had contact with. I have talked to many lawyers n nobody ive found does animal related cases.

  16. I used the Hartz flea and tick shampoo plus the frontline flea and tick liquid you pour down their back on my baby girl and now she has blisters and scabs and won’t quit scratching. Her hair is coming out in clumps and she is in bad shape. If I’d known about this dangerous shampoo before hand I would of never of bought it. Someone needs to seize production of this line of animal care products. I’m sooooo furious . They better hope my dog Patches don’t die.

  17. My chihuahua, Brownie, passed away 2 years ago. He started getting sick out of no where, then one day he had a seizure when my 10 year old daughter was walking him. After this day he wasnt the same, he wouldnt eat,he had no energy,he became weaker and weaker, I took him to the vet and they thought he was dying, and couldn’t give me an explanation, so I took him home and tried to nurse him back to health, and for the next month he tried to eat but he just couldn’t keep food down, he started vomiting blood and started having bloody bowel movements for almost a month, I eventually had to put him down. This was horrible and I had no idea it would be the flea medication I was bathing him with that killed him.

  18. We have been using their products for 7 years. We always thought our dog was acting crazy because he just did not like it. He would desperately try to remove it from his body. Turning over frantically on the carpet, rubbing against the chairs, bedding, or whatever he thinks will remove it. His body turned pink in areas which we thought he was allergic to the food possibly, never thought to connect it to HARTZ!!!!! He has been having seizures which began getting worse over time. We never knew what caused this to happen; but when they appeared to be worsening we took him to his veterinarian. His vet placed him on phenobarbital 2 times a day for life. Who would have ever linked it to Hartz shampoo or the flea drops that we spread down his spine!!!!! OMG 😱

  19. After reading these,I now realize I used Hartz shampoo on my black lab and he had a horrible reaction to it.Scared me not being able to help him.I knew it had to be associated with shampoo,he reacted violently immediately.I called the 800number on the bottle,they suggested another bath.I bathed again,which was a struggle,used a gallon of milk on him to soothe the burning.That seemed to help.I will NEVER buy Hartz products again.

  20. I would like to be contacted about being added to the lawsuit. My dog almost died and now has horrible chemical burns and suffering. I have all my documentation.
