Verified ReviewerYour product almost killed my dogs
- - Two dogs had severe reactions after flea products.
- - The vet said a severe reaction; both dogs were unable to walk until the next day.
I used your flea shampoo and flea collars on my two little dogs, Zoey and Samantha, 'dog-dog.' Less than four hours later, dog-dog went into a seizure, and Zoey was throwing up everywhere; neither one of them was able to walk until the next day. I thought they were going to die.
The vet said there was a severe reaction to your product. I put both of them back in the tub, got them free of your product, and held them both all night long, praying that nothing else was going to happen to them. I don't know how you can sell something that can do horrible, painful things to animals. It is just awful.
I'm beyond disappointed with your product; I'm screwed on the money I threw away to get it and still have fleas.
I'm too scared to give them anything else. It's just ridiculous how you are really treating your fellow Americans, your neighbors.
- Cheap
- Almost killed my dogs

- - Paid $32 at Walmart; no refund or return offered.
Great products you just can’t get anyone to handle the issue when u contact. Them
Today I purchased a two pack of ultra guard pro max flea and tick collar for dogs and puppies. Although the package says two should be inside I was met with only one collar in which I paid 32$ for at Walmart I called Walmart and tried to express to them my concern they completely turned me away saying they would not take the collar back or refund my money Im dissatisfied because I purchase these twice a year for the last 3 years and Ive never had this issue it works well for my pups but this was so unacceptable

Verified ReviewerZero stars....my cats fur was melted off!!
- - A dog ripped off a Hartz collar; skin irritation.
- - Cat wore it for 5 days; fur damaged and removed.
- - All pets have hair loss; Amazon refused refund.
I bought Hartz after doing some research, apparently not enough! I bought 6 total collars, 5 for the dogs and one for my cat.
One of my younger dogs ripped his collar off within the first few days; his skin was so irritated that he tore it up! My cat was wearing it for 5 days. I picked up my cat for some daily loves, and I'll be damned that he had some sores. I took off the collar; his fur where the collar was is completely gone!
Clumps of fur melted to the collar! I took photos and threw that horrid thing away. I also ripped them off all my animals and threw them all away. My middle dog has lost so much hair!
None of them are scratching anymore, but they are all losing hair all over their bodies. I'm so pissed off about this right now; I want to get my money back, but Amazon is refusing.
- Burn your animals skin removes their hair mainly where the collar goes animals loose hair all over their bodies
Preferred solution: Full refund

I bought the Cattraction rope-mouse toys with catnip and silvervine yesterday. The first time my cats played with them, both unraveled and the bell fell off one, all within 24 hours.
I scooped up the tiny bell part to prevent my cat from swallowing it! These are not put together well at all!

Verified Reviewer |Lethal
- - Kobe had tremors after Hartz Ultraguard Pro; treated in hospital.
- - Vet says no antidote; monitor pets for adverse reactions.
Still waiting for compensation
We rushed him to the hospital where he was given iv fluids and bathed several times to remove the medication residue from his body. The vet confirmed that he was having an adverse reaction to the medication and said there is no antidote and it was just us waiting to see if he would make it. We were heartbroken watching him shake uncontrollably for over 20 hrs straight. We brought him home, held him, fed him sugar water every 30 minutes throughout the day and night.
Prayed. Finally, at about 6am the following morning, he stopped shaking and subsequently regained his balance at about 9am. We bathed him again. Kobe survived .
He was one of the lucky ones who made it. Please read up on these products and keep a close watch on your pets if you decide to use it.
Im sharing this to warn all doggie and kitty parents to be aware of this devastating and potentially lethal side effect of these medications. A warning should be a black box warning, but its only in small print. Please keep close watch on your furry babies after administering these meds.
These side effects can happen anywhere from minutes to 72 hrs later and even if theyve had it before without an issue, per our vet. So many reports of adverse reactions , many resulting in deaths, have been filed against Hartz flea/tick products.
The flea collars have been reported to have a lot of incidences of adverse reactions as well.
- Potential of severe or lethal adverse reactions
Preferred solution: Would like my vet bill reimbursed to me
User's recommendation: Be wary!

Verified ReviewerRecycling
- - Packets are not recyclable; only the box is recyclable.
- - The reviewer asks the company to create recyclable packaging from creation to disposal.
Please consider creating recyclable delectables cat food packets. The box the packets come in is recyclable but not the packets themselves.
It is your responsibility, as a large company, to follow your product from creation to its final disposal. It could be a real selling point for your product! I'm sure I'm not the first person to ask you to put the time and money into creating a recyclable product. Thank you for your consideration.
If we work together we can heal our planet.
So far, it's the only one we have! Sincerely, Carol Dunn
User's recommendation: Don't buy until Hartz comes up with a recyclable product
Advertising problem
- - Bought a cat product and found a Hartz logo on the back.
- - They claim Hartz products are bad and the back label was to mislead buyers.
I bought delectable a for my cat and never knew that hartz were putting their logo on the back and i had been knew about how bad their products were. That was proof right there they know what they doing killing peoples pets, they know deletables werent gonna get sold as much thats why they put that damn label on the back!
My dog ended up almost choking on oinkes porkalicious chews
- - The chew came apart and lodged in the dog’s throat, causing gasping.
- - The reviewer wouldn’t recommend it.
I gave my dog one of these chews, later heard him gasping for air to find it was coming apart and was lodged down in his throat. I never feed him raw hide.
As this says its not made from beef hide.
I feel this is false information cause it definitely was being consumed like it. Would never recommend if you value your fur babies
User's recommendation: Don’t BUY them!!

Verified ReviewerRequest for Rate Adjustment
- - I booked in advance with Hertz and paid $109, then upgraded at pickup and was charged $81; I request a reconsideration of the charge.
Hello,
I hope this message finds you well. I made my booking in advance to secure a good rate for my trip. As an international student, I travel every year from Pittsburgh International Airport to Dulles International Airport for my summer vacation, and I often rely on different car rental services. Hertz has consistently been one of my favorites due to the excellent service I've received in the past.
However, I was disappointed with my recent experience. I made a reservation and paid $109 three weeks prior to my scheduled pick-up date. Unfortunately, due to unforeseen circumstances, I had to upgrade my car at the time of pick-up and was charged an additional $81. I had no choice but to accept the upgrade and pay the extra fee. While I understand that upgrades may incur additional costs, I was surprised by how high the extra charge was in comparison to my original payment.
As a loyal customer, I kindly request that you reconsider the rate for this rental and adjust the charge if possible. I truly value the service Hertz provides and hope to continue booking with your company in the future.
Thank you for your time and consideration.
Take care,
Sattam AlGasim
