SentryPro issues-Any Flea Product can kill

I have an 8 month old Chihuahua named Delilah. I noticed she was itching her knee area on her back leg and thought maybe she had recieved a flea from the backyard and since the weather has been getting warmer, it is the season to re-treat for fleas. I gave her SentryPro which is Sergent’s brand and not Hartz. The reason I want to post this here is because it is not just Hartz or Sergent’s brands that are lethal to some animals. After doing investigations on my own, it is all very bad and it can affect everyone, including your children. Within hours after giving my dog this treatment, her back leg began to jerk. It reminds me of a jack rabbit or a horse bucking someone off of them. The uncontrolled movements made me first think it was the flea bite irritating her or that the flea bit her again before dying. Unfortunately, I didn’t think much else of it until the symptoms got worse. My dog was laying with me, starting to jerk, and then the breathing issues came up. She started to have reverse sneezes. They were constant and I couldn’t stop them. I tried all the remedies on the internet that I could find at 3am and none of them worked. It took me about 30 minutes to figure out that this is not just reverse sneezing and fleas, it is an allergic reaction. I rushed my dog into the bathroom and began to scrub her down. Placing her in a towel, I held her close feeling the jerks and slight convulsions she had. Shaking of her head, kicking her feet, and the overwhelming need to gnaw on her feet and the soles of them. I rolled over on my bed to try and get us both more confortable and noticed that the bed was wet. Thinking at first she may have had an accident, I realized that it was on my pillow too where her face was laying prior to the bath. She was drooling!  I could now see spit collected in her mouth that was dripping from both sides.  I tried to give her water. The reverse sneezing stopped shortly after the bath but jerks and gnawing continued through the night. I was afraid to fall asleep wondering what I had done to her or if I caught it in time. I was angry because the back of the package only says that if SENSITIVITY OCCURS, WASH WITH MILD SOAP AND RINSE WITH LOTS OF WATER. Sensitivity? Isn’t sensitivity more like mild diarrhea? Maybe indigestion? Or a headache? I called the Consumer Affairs with the company today and they told me that they had a a caller just before mine that read things I had read on the internet and tried to discredit them by saying it was opinion. My problem was the box does not say, some side affects may include, seizures, vomiting, reverse sneezing (snorting), jerking, gnawing on limbs, and kidney failure..if this happens contact vet immediately. Product can be washed with DEGREASING Liquid Soap. If I had known these were the side affects, it would not have taken me so long to wash it off my dog. Instead they use sensitivity? I feel mis-informed. Betrayed. I bought this product at Petco. Where all the pets go. I thought that they would at least make sure they checked into the products that they sold before I bought them. I found forum after forum only to find that ALL dog over the counter products like this can be lethal. Hotspot, Hartz, SentryPro (sergent’s). The way these products work is two issues. One is, it is absorbed by the skin which then circulates it through the blood stream. It kills fleas by attacking the nervous system of the bugs. The pesticide cannot distinct between Dogs, bugs, kids, and adult’s nervous systems. Some are more SENSITIVE than others on absorbing this poison. Before you allow your child to wash the dog or do it yourself, consider these items and do your research. Dont take my word for it. What do I know? I found that some of these chemicals used may be linked to parkinsons disease. I found that the EPA doesn’t take into consideration how much dogs sleep with family members or share common items such as sleeping on bedding and cuddling. It is awful what happened to my baby, but I think she will recover. I do not think any of these products should be sold because even a child handles a dog with a flea collar and gives them a bath. It doesn’t have enough warnings NOR an information packet to tell us what to expect or do if something bad does happen. It should be our choice to purchase a product with knowledge of what we can expect. It is just like purchasing tylenol or a sleeping pills. Tell me what to look for so I know when to get scared at least! We always wonder what causes the increased defects and cancer rates other than a higher population and environment. Why dont we start considering poisons like this. They find medication and poisons in our water systems and it makes the news. Why hasn’t this? Just bothers me. I posted something on my myspace (yes I am retarded like that) and emailed people. But apparently some do not look into this kind of thing until it happens to them. I was one of them. Good luck to everyone. The EPA’s # is 800-858-7378 to report a poison issue that happened. I suggest EVERYONE take the time to file their report and issues. Thanks for letting me vent. Written from good ol’ Livermore, Ca.  PS. I see that Frontline is the only one that is less likely to cause these problems. Even K9 advantix has similar pesticides that Hartz uses. I hear that Keri Lotion is also good at preventing flea bites and can be used on the humans to prevent bites while you find other ways of getting rid of your flea problems.


My baby was very lucky.  She did not become ill but about 10 days after using Hartz, her fur started coming off, skin and all.  It came off in patchs around the neck about the size of 50 cent pieces.    She had been in my basement and I couldn’t think of anything she could have done to hurt herself but it looked like she had been cut with something sharp.  I had no idea that it was from Hartz.  I took her straight to the vet and that is when I found out what it was.  I no longer use Hartz or any of the over the counter flea preventions.  Like I said, we were very lucky that she didn’t get sick. I was shocked when my vet told me that they saw a lot of cats and they weren’t so lucky.

Hartz Flea & Tick Spray should be BANNED!

My husband & I found the most adorable 3-month old stray a few days ago and we took her inside & straight to the vet.  My vet gave her Hartz flea medicine & told us to follow up with the Hartz flea spray afterward.  Well, we did, & a few hours later, our precious tiny kitten could not stand up or walk & started having seizures.  We rushed her to the all night emergency pet clinic, & we were told that the Hartz had literally POISONED her.  They said she was in grave condition & she would have to have a blood transfusion, & right now she is being fed glucose sugar through an I.V. because she has not only been poisoned, but has developed anemia with seizures.  I have to wait atleast 24 hours to see if I can ever bring my new little fur-baby home.  It’s bad enough that Hartz is still on the market & has killed dozens of animals, but I found out the hard way that not all vets are even aware of this (or either they don’t care).  PLEASE, if you love your animals, do not use any Hartz products.  (Advantage works great, though)!

Can’t Believe it!

My cat died from using Hartz Flea and Tick drops 5 years ago! I posted my story on this site back then and I just can’t believe this is still happening! Why does this company continue to sell these products and why do people keep buying them?!!


I treated 4 cats with Hartz Flea and Tick powder within the last month. The one who got the most powder, Wobbles, a beautiful black kitty disappeared without a trace, most likely dying in agony under my house, where I can’t reach, as she never left the yard, EVER. She was deaf (she became deaf after being treated for ear mites 2 years previously, at the vet!) and only roamed about 10 feet into the yard and then back into the house. Minnie sickened for a week and died from kidney failure yesterday-Minnie, a 4 year old little tiger Manx, who loved to sit in the sun and beg for her ears and back to be scratched, and Cleo, who is now sickening and suffering from weightloss, salivation, lethargy and inappetence. Cleo, a pretty golden tiger cat is sick and I can’t afford to get her to the vet after spending over $200 on trying to save Minnie. There is no one to help me save her!!! And Inky, who I gave a bath to just a couple days after treating since she was scratching more with the powder on her than she did without it. But now Inky is COVERED with scabs and is losing some hair. I treated her with Frontline, two days ago,  hoping that it will help relieve what I hope is flea allergy and NOT a reaction to that deadly podwer. I hope that I haven’t poisoned her further by using two products. What can I do????
Hartz needs to pay in every way for what they’ve done to our pets!!!

Flea collar

I just purchased a flea collar for my dog. Since most stores in our area sell Hartz products there is not much choice about the products. I bought exactly the collar for the weight of my dog and put it on him yesterday. Today he can hardly open his eyes, they are red and swollen like from an allergie. I took the collor off right away and now I am watching him. If this is not better soon I have to see my vet.
I did have a problem with Hartz ones before, a cat almost died and I had to go to the vet several times which is expensive. Hartz appolozised when I complained. I found out many other people had problems with Hartz products. How come this products are so dangerous and pets have to suffer. I found out the problem with flea collars goes on for years, why are this products not recalled ? If only a few pets have this terrible reaction it is a few pets too many.

Winston’s seizures

I can’t believe this! I work night and got a call from my mom who stated that she gave Winston, my 3.5 mth old yellow lab, a bath with that new shampoo we bought. As my mom was drying him off she noticed he looked sleepy. She went to go get his bed and then when she came back she thought he was running in his sleep. As she got closer she realized that he was having a seizure. My mom, a doctor, grabbed the shampoo grabed everything that he had touched in the last 10 mins basiclly and jumped in the car to head to the vet. When arriving at the vet’s office (she called on her way), Winston finally started to just move around and start to be very playful again. At the vet’s office my mother was told that it was most likely he had low blood sugar and that honey would fix it. Thank GOD my mom is a DOCTOR b/c she inisted on blood test. The vet realizing that my mother knew what she was talking about did the blood test and then looked at the shampoo and stated that she was right and that they would give Winston a bath and make sure that he would be fine.. We never used that shampoo or their products again and Winston has never had a seizure again. The vet apoglized to my mom about the inisted and has since stopped all his patients (or those that listen) from using products that they make.

Hartz employees are dying

My mother passed away at 55  a couple of years ago,but for the past 10 or 15 years she had failing health which started out as a nervous breakdown and progressed into epilepsy which the doctors could never pinpoint or cure with medication or surgery, lately I am seeing co-workers of hers dying at young ages as well ,,in their 50’s from different things such as epilepsy and are developing alzheimers and other ailments in their early years,,I am just seeing this develop as a pattern and I dont really think that any of these people have any idea that some connection exists regarding their exposure to Hartz products during their employment..If anyone out there knows of any more Hartz employees with the same problems please let this forum know so that maybe some of the living can look back and see that they may have also been exposed or someone who has health problems but cant explain why.

Seargeant’s Gold is AWFUL

I bathed my dog in regular shampoo and when she was dry, I applied the "gold".  Proper dose for size and weight.  Within a few hours she began shivering and became very hyper.  She couldn’t sit still and she was whining terribly.  She had what appeared to be hiccups.  This stuff nearly killed my litttle dog – It should be taken off the market.
