had a moment of stupidity. I already knew from when I was a kid that this company has bad products from the news in the 80s and 90s.Used it again tonight and 2 hours later my 12 pound mixed breed baby girl was lethargic and her head was trembling. I snatched her up and bathed her fast,in tears at my stupidity. called the Hartz ppl.they don’t care.wasn’t their product.she is allergic to something..duhhhhhh their poison !! she is now fine,called her vet.he knew right away.has seen it before. so i am looking for something organic to help.she is a happy girl now. for a few hours of illness and mom’s guilty feelings,she has been getting treats…lol..happy story here..i wish everyone could have one too. sorry for every one’s loss and pain. I love all pets and this company has to be stopped !!!!

My Black cat Church always has worms…being black they are soooo noticeable.

I use to get a pill from vet at $7.00 a pill…the worms were back again within weeks

church and her sister Omalley are indoor cats…but have a large screened in patio to get the outdoor thing.

I gave Church a dose of the hartz rid worm paste…mixed in with a big portion of canned cat food ( a treat for my 2 cats)

luckily she didnt eat it…as she will eat anything

after reading the stories about Hartz products…I will never buy again

I used Hartz Ultragard on my cat, now she’s almost dead.  I should have never used that poison on her.  I couldn’t believe all the horrible stories that I read here.  And they have the guts to keep selling it?  Why can’t they be stopped?  This is ridiculus.

I am telling everyone to stay clear of that horrible poison.  I am telling them to on there site: www.hartzultragard.com maybe if we all tell them to do it they will?

Have to go to the vet and spend a fortune to save her life.  Good news is hartz is glad to pay for it.  They do this all day long, pay for their poison.

Last night my girlfriend asked me if it was alright to use a 2ml dose of Hartz Canada One Spot on her cat Cheeba. After inspecting the packaging and making sure the weight/dose was correct I said it seemed ok to use and she held the cat while I applied the One Spot. Afew hours later my girlfriend told me she thought the cat was acting weird by curling into her and she said shaking every so often. When I checked the cat for her I didn’t notice any shaking and figured he was cuddling although she said he normally doesn’t just come up and do that and she normally has to go get him to cuddle, but anyhow we came to the conclusion he was sucking up and maybe shaking because he was scarred he was going to get in trouble for urinating/spraying somewhere in the house because thats been a big problem with the cat recently. So anyways I went to bed to be awakened by a screaming/crying frantic girlfriend to come check out the cat and something was wrong, a little annoyed thinking she was over-reacting as usual I got up and come out to be horrified after seeing the cat trembling uncontrollably and I would say almost to the point of a seizure but he was still sort of standing but very very disoriented that when he was trying to get from the couch to the floor he flopped on his head but the symptom that had me the most worried was he kept opening his mouth real wide and closing it which made this horrible clicking noise as if his jaw was coming off track or something. I swear I thought the cat was going to keel over and die right there on the spot and with my girlfriend screaming even more hysterically after she seen my worried expression which in turn made our 18 mo. baby just as upset (the cat by the way is my babies best friend and she laughs her head off at that cat everyday but I was sure she didn’t understand the situation and was just reacting to mommy) so I told my girlfriend she wasn’t helping matters and totake the baby in the room try and calm down and I will help the cat. We are a very low income family so we knew a vet was out of the question (which I’m sure just made the GF more upset) so I put the cat in the center of the room with a blanket and went straight to the computer to research the Hartz One Spot product as I knew immediately that was the cause and found this site. After reading only a few posts my heart sank into the pit of my stomach for the fear of the family cat dying but I had also gotten some practical solutions to the problem. I had started to run a bath for the cat and gotten the dawn dish soap to help get rid of the oily product on him the problem was though our cat has never liked baths and I was scared in this condition it might make things worse and my fears were correct as i slowly, calmly placed the cat in the bath it started flailing but with its horrible coordination and spasms it just made things bad as it fell onto his back and just went stiff allowing his head to submerge in the only inch of water in the tub and at that moment I thought he had died. I quickly scooped him up instantly after he fell over and placed him on his stomach with a towel over him and started petting him to try and comfort him to let him know the whole bath ordeal in his current situation was over and he could calm down and to my suprise he wasn’t dead but I guess had momentarily went into shock. So after a good 15mins of comforting him on the floor of the bathroom I moved him back into the center of the living room and gotten a pot of very warm water and the dawn dish soap to try and remove this poison by slowly lathering him up and stroking the soap off with a wet cloth which went so much better than the attempted bath and I washed him off as best I could with this method. I had gotten my GF to buy some vitamin c as someones post said a vet recommended that but the cat wasn’t responsive enough at this point to eat or drink. I wrapped him in a towel and put him on the couch to dry and hopefully start recovering a bit so I had told my GF to go to bed and get some sleep because she was still just extremely upset seeing him shake uncontrollably and opening his jaw with the clicking noise so when she was leaving she told me if he dies to please make him a little coffin and remove his body outside for burial the next day so she wouldn’t wake up to see him dead which her instructions sort of went without saying as I was going to do that anyways. At that point we both were pretty convinced the cat was not going to make it through the night. Around 4-5 hours later of comforting the cat and watching his condition not improve much I had went for a smoke and said a few prayers for the cat when I came back inside i sat next to him and started to gently pet him and for the first time he actually looked up at me but still had all his previous conditions which included his pupils being black and huge to where you could see no white. A miracle had came for this family though and I truly believe it to have started when he looked up at me when i came back inside because every 30mins after that his condition just kept improving to where his uncontrolled shaking became slight jerks in his legs while laying, his eyes were almost returned to normal, and he was not opening his mouth anymore with that horribly clicking noise. The big thing besides the improvement to his symptoms that let me know he was going to be alright was the way he was responding to me comforting him such as pushing his head into my hand while petting him and raising his bum when getting pet on his behind. I was so happy he was going to make it and I wanted to wake my gf but I held myself back so she could have a huge suprise. When my GF woke up and started down the hall and saw the cat wasn’t in his towel next to me he face sank and she started to swell up with tears but as she continued into the living room she saw him up and walking around my feet and her reaction had totally changed…well sort of, instead of crying out of sadness she was crying because she was so happy and was saying “oh my god i can’t believe he’s alright I thought for sure when i went to bed he was going to die and when i came out here and saw his towel but no cat I thought he was a goner”. Her reaction and the cat himself being alright made staying up with him all those hours more than worth it. Now that my story is basically been told I would now like to move on with my conclusion which is my hatred for Hartz and companies just like it which sells poison for our pets with such disregard and makes a profit from killing our beloved pets. After my ordeal and reading tons of information on this situation I just can’t believe this has been going on for many many years and countless pets have died and it hasn’t really gotten the attention it deserves. The public needs to be aware of these products and the more than certain harm it will cause your pet but it also needs to be taken off the shelves and banned. I am appalled I paid a merchant of death my hard earned money to be sold poison to kill my families beloved pet/friend/family. These are not just our pets these are our friends, our family, our children and it is totally immoral for these companies to be selling us poison in turn killing our ‘friends/family/children’ and actually getting away with it scott-free. I was so upset when I had seen the symptom for myself as I felt I had personally murdered a member of my own family with my own hands once by telling my GF the product should be fine to use, twice by putting that poison on him, and third by brushing off the early warning signs that my GF pointed out. I am wounded deeply by the experience and god forbid if our feline family member had actually died I would have always lived with a sense of regret and pain for the whole ordeal. I am obviously one of many lives these companies have severely effected and I pray for everyone who has lost their pets/friends/family/children to these obvious evil, malicious, profiteering companies and I also pray they will get what is coming to them. I urge everyone to report these companies as I can’t believe they can actually sell these products and get away with it when in my country Canada I can’t even buy a flea bomb because they are toxic but I can go ahead and pick up a product which doesn’t properly make you aware your treating your pet with poison and will most certainly kill them. Anyways sorry for the long post I had a lot to get off my chest and I am truly sincere to everyone effected by these malicious companies.

I had used this product on my three dogs several months ago, with no obvious problems.  However, tonight,  about an hour or so after application, my female Doberman started drooling horribly.  I searched the ‘web and found that this is a common problem.  As recommended, I washed her immediately in dishwashing liquid and am now keeping an eye on her as I have read that seizures and other neurological problems can manifest.

Don’t think because you have used it before that your pet will be safe, or that only small dogs have these problems.  My dog weighs about 65 lbs and is 1-1/2 years old and very healthy (until now).  I used the proper size (up to 61 lbs) and I also used it on my other two Dobermans tonight, who appear fine (but also needed to have it washed off to further protect her and them).  It was applied to her first, as she was first out of the bath.  I don’t know if she might have licked them, or what… but I will never use these over-the-counter flea products again, and I urge you to find another solution.  I will contact my vet in the am and get a prescription.  I was avoiding it because for my dog’s weight (65, 75, and 112) it is VERY expensive.  However, their health and well being is the most important, and I just hope that the lesson I learned doesn’t have any lasting health effects for my furbabies.

I used this treatment for my two dogs and both had a reaction that made them very sick, They cried, scrached, rolled on the floor and chewed their feet.I took them to the Vet and after treatment, I brought them home both are still sick but seem to be getting better, but I don’t know yet. How can a company that is supposed to help animals, create such toxic crap!!!

My poor kitty Shady Marie likes to go outside supervised on a harness during the summer months.  I have always purchased him flea collars to wear during those months.  I recently purchased a Hartz flea collar, I believe it was the 3 in 1 collar.  It was white with a purple stripe.  My usually vivacious pet was markedly changed within hours of putting on the collar.  He was hiding under my bed and was very lethargic, behaviors that are uncommon for him.  He has worn flea collars in the past and never behaved in this manner.  I researched and found this site.  Thankfully, I have a wonderful boyfriend who was also alerted by Shady’s odd and sickly behavior.  We immediately removed the collar and shampooed him. Within a short period of time, it was obvious he was feeling much better.  I cannot imagine what his fate would have been had I not removed this devilish collar.  This product should be banned, or at least come with a warning.  Even cigarettes have warnings.  Protect your pet, do not purchase this product.  Kristyn A Lowing

I have a pair of cats - brothers - rescues, as all my cats have always been, and at the time I also had an older female. These sweet boys are my angels, and naturally I did not want them getting bugged by fleas, so, even though they are strictly indoor, I got them all Hartz flea collars. Within a day all were sick - drooling, unable to eat, listless. It didn’t occur to me at first that the collars were the problem, but when I called the vet, that was the first thing he asked. Apparently, by grooming each other, they were getting doubly sick from the collar’s poison.

Needless to say I removed them immediately, and the larger brother recovered quickly - the smaller brother took longer, and the female never completely recovered. She continued to lose weight and seemed emotionally traumatized. The boys kept her company and comforted her as best they could, but rather than living another few years, as she ought to have, since she had been in good health and was only 12 years old, she slowly faded and died less than 6 months later.

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.
