Important Information

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.

Too good to be true

This very inexpensive 7 month flea collar had about the same rating as the Serento flea collar I usually buy for a significantly higher price but since the stars were the same pretty much I gave it a try. I really don't see it helping or doing anything for my larger size dog, so just wasted that money and time just to go with what I know already works.

Awesome & It Works!

FOR THE PRICE? IT NOT ONLY KEPT AWAY THE FLEAS AND TICKS ON MY BABY (PRINCESS). IT WAS AT A PRICE I COULD AFFORD. ESPECIALLY, THE TIMES WE'RE LIVING IN NOW! THANK YOU HARTZ BRAND!! PLEASE, KEEP IT THE WAY IT IS.

Didn't work

I'm sure its because the ticks/fleas in my area are intense for no reason but I bought 2 for my Yorkie and Frenchie and this is the first time a flea collar hasn't worked. Its barely been 2 months and it wasn't even working in the first

works but not really

it only works in the upper part of the body, my 2 dogs had been wearing this and they still got fleas, most of the fleas stayed in the lower part of their body and genitals.

This flea collar did not work for a day. It's like it is attracting flesh to the poor dog.
