Hartz Ultra Guard and Dizzy Dog

I gave my 90lb German Shephard a few drops of the 60lb Hartz Ultraguard.  I had only found one flea and was not wanting to medicate him for a full blown outbreak.  We are lucky in that we have never really had fleas or ticks but he will pick up occassional pests on our field outings.  This morning he literally fell into the side of the house and while hiking his leg on a tree almost fell over again.  We immediately went to the vet.  $200 later and blood tests the vet is not sure what is wrong with him.  He instructed me to give him a good bath with dishsoap to cut the oil in the Hartz poison.  He was a perfectly healthy dog and now he looks dizzy and clearly feels bad.  How can Hartz Ultraguard be allowed to remain on the shelves to claim more victims?   I feel so bad that I have poisoned my little boy and those sad eyes keep asking me “whats wrong mommy”  I am so upset over this….

My story is different but listen

Okay, about two months ago, my dad, who can’t read, put flea medicine on my cat that was meant for the dogs (please don’t blame me for this. I feel guilty enough as is). She suffered from permethrin poisoning. Thankfully, we got her to a vet so that she could get proper medical care. Anyways, I did some research and discovered that this pesticide, which is dangerous to cats, was being put in cat flea meds. Hartz is among one of the many medications included. Something needs to be done about this! I know my story is different from everyone else’s but I wanted to get the word out. I just hope someone will listen.

worried about my best friend

I purchased the Hartz product for my 12 1/2 lb, 12 year old frisky happy  Bishion / Lakeland Terrier in April 2010. I bought it because of it’s claim to do what the other stuff I was using, it was less expensive  and  because I thought Hartz was a name I recognized to be around for many years ( and therefore could be trusted?! ” ) I applied it that eve.  My dog did not exhibit any real noticeable change until I applied his second month’s treatment.   I noticed he  lost his hearing, has been lethargic, doesn’t eat AND the fleas are even worse!!! We live on the beach, so the sand fleas can be intense, but it was always controlled by his other treatment, and he had no ill effects with that treatment. Hartz needs to be stopped! I am afraid to treat my dog w/ even his old treatment for fear he has toxicity. My dog is suffering, I am suffering, my dog is in pain, weak and  still covered with fleas. He is lethargic, does not respond to noise yet  and I am calling my vet. I also sure wish I had the foresight to look up Hartz before this treatment, will ALWAYS in the future, and will tell everyone I know!


My 2 year old cat died today (july 4) after using Hartz UltraGuard Onespot for cats.  I put it on him last week. I thought his lethargy and loss of appetite would pass.  he stopped eating. Last night he started walking funny as if he was dizzy.  when i came home he was asleep IN his cat box.  today before i could get him to a vet he had a seizure and died in the middle of my livingroom in front of my 7 year old daughter. We are both heart broken and devesated.  I feel immense guilt for putting this poison on him..  I thought his comdition was temporary and I wish i would have taken him to the vet right away last week.  I was told that sometimes pets have a slight reaction to the chemicals but it can pass. I know not all animals will die from this product  as some are more sensitive to the chemicals than others, but this is not a chance i will ever be willing to take again.   I now know there are  many ways to treat fleas other than putting pyrethrins on your cat.  It is logical that if these chemicals are hazardous to humans they surely are for a pet as well. Why does it suddenly seem okay to put a dangerous chemical on your cat just because the package has a robust looking cat on the package? Sure these chemicals kill fleas (if they have not a resistance yet) but they will also kill your pet.

After reading  letters and articles extensively accross the internet it is abundantly clear to me that Hartz’s main intrest is their bottom line, as many of their products have not been tested appropriately and are toxic or useless. I have noticed while shopping  in the pet isles of many stores Hartz is the only brand available, amazing for such awful products.  I will stress with much importance to everyone I know to avoid all Hartz products and I will pesonally boycott them.

I have noticed on the lable of the product it is not stated that Hartz UltraGuard Onespot is systemic, which means it will get into the blood stream and into the nervous system.  For $4.99 I thought (silly, naive me) that it would be a simple topical oinment as some other kinds of flea medicines.  I did wash him 3 times with Dawn dishsoap  after I noticed he was acting  unsusal an realized his condition was not mild enought to seem temporary.  It also does not state anywhere on the package not to use the product more than one time a month which leaves me concerned that since the product doesn’t work, a person may be inclined to apply more.  If one dose killed my cat in under a week think what pain and suffering two doses would cause a pet.

UltraGaurd Flea & Tick Collar (Near?) Tragedy

I found a lost and lonely kitten out in the middle of the woods in the rain.  Lost, soaked, and shivering she followed me to the car and jumped in. Took her home, gave a bath, and some food.  combed her with flea comb, no fleas or ticks.  went to store, bought food, litter and box, and a Hartz collar to keep fleas away.  Less than two days later, she started to walk like she was drunk.  i had noticed her cleaning herself and licking her chest just under the collar the night before.  Researched online, found this site and other info,  Removed the collar, gave her bath with mild dish soap.  Within an hour she was doing better.  Been two hours now and tomorrow morn will see how she is.  Hate to think i caused her this problem, had i only  known about these collars being bad for some cats…….. i never would have used it.  Thank you for this site.

Hartz Ultraguard A BIG NO NO…

I have always used Advantage in the past on my male and female Boxer. My husband was in an accident and we suffered a 40% loss of income to the household. Therefore I decided to try Hartz Ultraguard to save a bit of money. Well My make, Hunter did okay with it but my female Sadie was not so fortunate. She had a severe reaction to the treatment which initially statrted as some redness on her belly and quickly progressed to a severe skin infection and non-stop vomitting. The symptoms continued even after washing the treatment off of her. She was near respritory and kidney faliure when we arrived at the vet because she had been poisoned by the treatment. We are in day two of the treatment and she is still vomitting and extremely itchy. I do not understand how these products are still on the market. My vet said that she has had animals come in with permanent neurological damage, siezing, and some have even died.

This has got to STOP…

Did drops cause vomit?

When I was growing up, my family had a cat that refused to eat anything other than Fancy Feast.  When my family fell on hard times, this was a bit of a problem, expense-wise.  When my husband and I got a dog, we certainly didn’t want to be eaten out of house and home.  Unfortunately, the puppy seemed to always be hungry and tried to eat his feces whenever he got the chance, so we put him on a better (more expensive) food, which has made a difference for the better.  Our puppy was seen by our vet after we got him and was given one of the big name flea and tick products there, with no problems, but we had to cut costs somewhere, so when it came time to get more flea/tick medicine, we went to the store and got Hartz drops.  Like others on this site, I figured that the worst that could happen was that the stuff just wouldn’t work, and he would get flea infested.

A couple of days ago, I found a tick when I was bathing him (I removed this and saved it in a cup with alcohol–I always do for a couple of days, just in case of illness).  After his bath, I got the drops and read the container to double-check the directions.  I was a little miffed that I had to put it down his whole back, but not as miffed as I was when I saw that it should, under no circumstances, be used on cats.  We also have a cat, and I was a little worried, but then realized that he should be fine because he hates the dog and avoids him like the plague.  The cat has been fine, by the way, but I was already considering buying something else next time, just to be safe.  After the application, I put the dog in his crate for a while, just so the stuff wouldn’t get spread around anywhere while it was fresh.  He has been fine, except for slightly flaky skin and loose hairs around the application site.

I woke up this morning, less than 48 hours later, and he had thrown up.  I had heard him coughing when I woke up, so I know it was recent.  He was his usual, happy self when I opened his crate, then he threw up again.  I cleaned everything and removed his bedding and put him back in his crate while I took care of some things, and he threw up a third time.  After first using the drops, I looked up reviews to see if they worked at all (stupid, I know, I know…).  That’s when I found this site (along with all the others that say Hartz doesn’t even work well).  I informed my husband that, due to the intense toxcicity to cats, we would not use the product anymore, even on the dog, but I figured I would at least let it run its course this month.  Now that he has thrown up, though, I bathed him with dawn, just to be safe, and he seems to be fine now.  I don’t think he could have gotten into anything the night before to make him vomit, because he would have done it the night before.  I don’t know if it was tick related.  I don’t know if it was the drops.  Maybe he just felt funny this morning and is fine now all on his own.  Just the same, I won’t be using Hartz drops anymore.

Hartz flea and tick drops

December 2009, 2 weeks before x-mas my cat Spunky died After applying Hartz flea and tick drops. Now my cat Chloe is at the Central Emergency Pet Hospital in Coquitlam BC for the same thing but she is going to be ok (THANK GOD). But my cat Spunky didn’t survive. On the way to the emerg pet hospital Spunky died in his cat carrier and when we arrived we was already dead. I have never been through something like ever. I want to sue Hartz for this shitty product and I have just learned is very toxic to cats and some dogs. They need to take this product off the store shelves as I am sooo pissed
