I put on the hartz ultraguard plus collar for dogs on my dog. I didn’t touch the collar for more than 2 minutes, and washed my hands immediately afterwards, but my skin has been feeling so weird…it doesn’t hurt or anything…it’s just sort of irritated. I don’t feel normal but don’t know if I should be going to the emergency room. I’ve washed my hands numerous times, and I still feel sort of funny. I obviously took the collar off my dog immediately because that scared me, and then I started reading these reviews…my dog doesn’t seem affected but I’m not going to sit around and let her. She seems okay but I’m still kind of worried. What do I do?

My beloved Fred

Fred was my companion for the past 9 years. He was a big cat with a bigger heart. He knew no stranger. We began having a flea problem in our basement which worked its way upstairs, so I gave my cats what seemed like the best flea control for the money. I only wish I had known a few weeks ago what I know now. Fred passed away this morning of an anemic reaction as I did all I could to wash the horrid flea infestation from him, the exact thing I thought I was preventing with the Hartz product I purchased. Not only did it not work, it deteriorated his health from a vivacious large cat to the point of dying from a flea infestation. I pray people realize the dangers of Hartz products before they learn through the loss of a beloved pet, as I did. I will miss you, Fred, but I swear to you I will do all I can so that your death will not be in vain.

We Got Lucky

A couple weeks ago I put a Hartz tick and flea collar on my cat Spaz. Last night it fell off and this morning I noticed that my poor baby had lost all of his hair around his neck where the collar was and there was a white substance on it. It wasn’t bothering him but I gave him a bath and now that the residue is off it looks a lot better. I wish I had known about this site before I put one on my fur baby. My kids were so worried about our Spaz. I will never purchase another Hartz product again. From the looks of the previous posts we definitely got lucky this time.

Sargeant’s Green pet death

Sargeant’s Green potential pet poisoning which eventually led to death of 25 lb Cocker Spaniel and presents allergic symptoms in human (myself); rash, itching, shortness of breath, swelling of vessels.Other pet displays symptoms of heat stroke.I applied on June 1st when she first showed slownes or laziness which I thought was the new harness. Later in month, I reapplied mid month because fleas were so bad(box says 15lb pet even puppies) She eventually became ill and after about 3 days of decreased activity and minimal vomiting the night before(small amt. of dark green mucus?), vet diagnosed without blood test iron deficient (even though I told him about the Sargeant’s Green reaction since maybe June 1st) and was finally able to bring home with meds.She died ThursdayAM after breathing difficulty night before even though she had showed signs of improvement.Vets refused to take body to make sure not in coma without cash, refusing to bill.Had previously reported to poison control after vet iron deficient diagnosis.SPCA hotline was nice, but local SPCA insulted me for buying an over the counter med.I’d sort of like to complain about the vet also because he ignored my repeated information about potential poisoning/allergic reaction. I have a rash, swelling and itching in addition to shortness of breath from the fleas that took some of the flea med. Although the taste of it isn’t bad, I have a very dry mouth and swelling in my throat at times, but not constant.She was a very active 7yo dog, even though she had problems with her eyesite.She was a strong walker until June 1st which I associated with the harness. I am upset with the vet that he ignored the information about Sargeant’s Green and gave me more flea meds that were even stronger after a potential poisoning(Ovitrol).; (veterinarian) Sunapee NH. I am wondering if he knew the people who developed the product. I had to bring her to a crematory because I had no place to keep her and am hoping she was not in a coma. Other dog sometimes displays signs of heat stroke, but is slightly larger. I reported to Sargeant’s Green online and poison control after the vet kept her overnite, stating she might not make it because of iron deficiency. She ate fish. This was very abnormal activity for her.I feel as though the vet ignored my valuable information, but doesn’t mind billing me even though she’s dead. Especially since some reaction have been passed off to myself, the human. I gave CPR.

Lost a kitten yesterday :(

I had to have 1 of my 5, 4 week old kittens euthanized yesterday, and I believe it was due to Hartz KMR. I had just bought a new container of the powdered version, and had given them a few feedings from it.  At 6am yesterday, I noticed 1 of them was sleeping in the litter box when I went into their room to feed them. I didnt think much of it, being little ones, theyre sometimes silly like that. So I startled her to feed her, and something was definitely NOT right. She was very limp, almost unresponsive…she took a couple sips of the KMR, but was more biting the nipple, as if to stop the flow of it. I think she knew better than I did of what was going on 🙁  I laid her on the heating pad, thinking maybe she was just extra tired or something. I went back in for their 11am feeding, and she was still in the same spot, looking lifeless, laying limply. I picked her up and she could barely meow. Her head and limbs just dangled, her eyes were open, but she was unresponsive, and had wet herself. I was so scared. I gave her a warm bath, to wash her mess off her, and thinking maybe she had some poo that needed to come out, and that the bath would wake her up a bit. No luck 🙁 I sat with her in this condition all day. After awhile her mouth started opening up and her tongue was starting to hang out a bit. Finally at 3pm, I took her over to the vet’s office. They checked her blood sugar levels, which were fine. Her temperature was a little low, but nothing super serious. They couldnt figure out what was wrong. In the end, the vet chalked it up to being a virus or some kind of birth defect, and suggested the most humane thing to do, was to put her down.  So I did. I havent cried that hard in a long time. I brought her home, and buried her next to a flowering bush in our yard. I took a look at this website, thinking maybe it had something to do with the KMR. Then I went to our local pet store and bought PetAg KMR. Evening feeding time came around for the others, and as soon as I walk into their room, I see that the rest of them have the SAME SYMPTOMS.  Wandering around the room, seeming confused, didnt really want to eat (but I did get them to take some of the other KMR), stumbling and falling over, lethargic. One was already laying on the floor, seemingly lifeless.  I held her close to me for a long while, eventually wrapping her in my shirt I wore all day, and placing her on a towel in the cat carrier for the night. I was thinking I would wake up to them all dead. At 530 this morning, they had ALL come back to their normal selves, even the one I thought was surely going to die. I attribute it to having the different KMR in their systems, and the Hartz leaving their systems throughout the night. I lost one baby due to this HORRID PRODUCT. Never again! I will yell it from the rooftop that this product, and other Hartz products, are DANGEROUS KILLERS!!!!!!

Will you sign my petition?

I have created a petition urging Hartz, Sergeant’s, and other brands to use natural ingredients so our pets no longer have to suffer. This is not spam or a virus. This is a real petition created by me on Change.org. I have never used these products, but I am absolutely heartbroken for those of you that have and have lost a pet or you had to watch your pet suffer. It is time these companies start caring about our pets!!!!!!! http://www.change.org/petitions/hartz-flea-and-ticks-start-using-natural-ingredients-in-flea-medication-so-our-pets-no-longer-have-to-suffer?utm_campaign=petition_created&utm_medium=email&utm_source=guides  This is the link to my petition. I would greatly appreciate your time spent signing the petition and sharing it with others. I know this petition cannot bring back your pet or make up for the sickness your pet had to go through, but this petition will hopefully help spread awareness about these products.

Our baby girl died and its because of Hartz Kitten Milk Replacer.

About two weeks ago our cat gave birth to four kittens. Two days after they were born a chain of tragic events happened and two of the kittens ended up dying, while one we had to take to the vet immediately because her umbilical cord was pulled and she needed to be operated on and stitched up. (the fourth kitten was in no way harmed) We ended up getting the kitten back and she was doing really well but we had to give her the amoxicillin in case she had any type of infection due to the open wound. My boyfriend and I were giving her and her brother the kitten milk replacer by Hartz bcause we literally spent every penny we had on the operation for the little girl and the antibiotics and the Hartz formula was the cheapest formula (the liquid formula) that “stayed fresh” the longest amount of time.  A couple days ago the little girl started losing her appetite and was really lethargic, and wasn’t going to the bathroom the way she was supposed to. We did the stimulating with a warm damp rag for her and her brother and he started going regularly, but her progress seemed to start going backwards. Then Monday she wouldn’t eat even half of what she was supposed to be eating, she barely moved, she had her mouth open and seemed maybe like she was dehydrated? and screamed out in pain when we tried to help her go to the bathroom. Then within only an hour or two you didn’t have to even touch her for her to scream out, and the cry was not a normal kitten cry. It was a cry of pure pain and discomfort. I called around to different vets, even the one who operated on her, who didn’t seem all that concerned, till I talked to someone at an Animal ER. The man told us to go ahead and bring her in. We rushed her to the ER and at that point I didn’t think she was even gonna make it to the hospital. She was only a week and a couple days old. Her eyes weren’t even open yet. We got her there and they took her in the back and put her on oxygen immediately and a couple minutes later called us back. They weren’t completely sure what was wrong with her, but assuming because she had been operated on already and had an open wound while being so tiny that she had caught an infection. Her temperature was too low. They called it Peritonitis and said she needed to be put down. There was nothing they could do. They said there was nothing we could do. They didn’t try anything, just assumed. And we believed them. That little girl didn’t have a chance at life. She was innocent and sweet and we let it happen to her. Reading these reviews and seeing that a lot of her symptoms matches up with those of your kittens, some saved, some lost. It makes me sick to my stomach and brings tears to my eyes. Now her brother is starting to have some of the same symptoms which is what caused me to look this up in the first place. I would have never known. We just switched his formula to the powdered KMR which is supposed to be the best. We’re trying to get the other formula out of his system, and are hoping its not too late for him. We will always hold the guilt for our little girl who didn’t make it and that we were too trusting and not educated enough about to prevent this from happening. I am so sorry for everyone who lost a kitten, or puppy, or anything to Hartz. Please if you haven’t started using it yet – don’t take the chance. Its not worth the risk or the loss. It WILL leave you heartbroken. I will never forget this, or her.

Thanks for making this website.

Hartz Ultra Guard Flea and Tick Drops

Hartz Tick Drops… if applied to your pet…

Wash them off your animal IMMEDIATLEY ! Take that product back to walmart and demand your money back.

My Dog got a severe bleeding nose less then 15 mins of applying a 30lb one month dose. My dog is 100lb King Doberman, he went into convulsions, and seemed dissoriented, we rushed him into the shower, used dawn dishsoap on him, and scrubbed him all over. He seems to be doing better now, that stuff is pure poison!

The blood coming out of his nose was very liquidy, almost like it was half blood half water. And very very Red in color. Nothing like this has every happened to my dog before. I’d rather pull ticks off him with tweazers then have him die from poison.
