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.

How long does it take for the collar to work? And how do i know if its working?
Answer by ChewyDec 07, 2018
The collar will begin to kill fleas, ticks and flea eggs and larvae immediately. Its full protections against harder to kill ticks will be built up within a few days after being placed on the pet.

Can this be used on dogs with sensitive skin

If your dog's skin is sensitive, please ask your veterinarian if this treatment is right for them.

bad review here

I’ve always used Soresto collars I’ve never had any problems with the fleas. Due to the cost, I decided to try these flea collars, my dogs ended up with fleas. I bathe my dogs every week. Thank goodness. I’m going back to. SORESTO collars

Hartz flea collar

I purchased these collars on June 6th and it is June 18th. I have used the Seresto collars for years with no issue what so ever. With the way things are today I was trying to save a few dollars…big mistake! I noticed a my girl started scratching at her neck a few days ago. Today I looked under her collars, and to my surprise I saw this. She has a smaller sore on the top of her neck and another on the side. All of this within a week. I would not recommend this to anyone and definitely will not be repurchasing. I guess the saying is true..you get what you pay for.

Great collars!

Within a day of putting this collar on my dog, a tick was found in my bed that had fallen off of him. This collar works great!

good alternative

My dogs are allergic to products like Frontline. These collars work, and dogs have no bad reaction.
