Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Got this as an added layer of protection for my 3 1/2 y/o Boxer bc we live by the beach. She takes oral meds for fleas/ticks, but they can be sneaky. Best not to take any chances. The pup wears it with her regular collar, so she kinda looks boho with that extra necklace. As always, Chewy came through with a great price and quick turnaround on the order.
Hartz flee and tick collar
I tried this collar for the 1st time on my dog, and it works great! I'm so glad it worked, because the last collar I used that cost $28.00 did NOT work but for three days, then my dog was scratching horribly so. I went on Chewy and ordered the Hertz collar 3 months ago, and it is still working!!! Thank you Hertz, and thank you Chewy for selling this product!!
I had ordered Hartz fleas and tick collars because it is a back up for the upcoming spring season. With Hartz I know that neither of our 2 dogs will have any adverse reaction as I have had with other dogs using more expensive collars. Shopping through Chewy just makes taking care of our pooches so much easier!
Worst I’ve ever seen
Extremely disappointed! My dog has acquired more tics since wearing this than ever before! HORRIBLE
Not one problem
I have always bought these and a topical to use 2 times through the summer, they work for me.
waste of money
Didn’t work on my 30lb or my 50lb dog. they still have fleas and ticks.
Hartz flea and tick collar
Seems to be working fine. Smells good too! Doesn't irritate my dogs neck either.
Don’t even waste $1
I know “you get what you pay for” But I wanted to try a cheaper solution for my dogs and cat. Well I tried and it sucks… Doesn’t even work for one day. Honest review! This collar has been on my cat and dogs for the appropriate size and it doesn’t work at all. I waited to see if maybe a few weeks in, it will be good… nope now my house has fleas and I have to totally debug everything. I NEVERRR had this issue before! So thanks Hertz UltraGaurd for irrigation my pets necks, not working, and wasting my money.
Hartz flea collar
Love the Hartz flea collar! Our lab has allergies & couldn't wear any other brand of flea collar without throwing up & diarrhea. We tried 5 different brands & ended up giving them away but he is doing very well with Hartz! I am so relieved :-)
Good Tick Collar
So far so good, have been plagued with ticks in my yard this summer and got tired of pulling them off the dogs so got these I used to use another product but too expensive when you have 3 dogs so figured I would try this, I have not had any ticks since putting them on the dogs and I did up until I used the collar so thinking it is working.
