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.

No

Found the product to be ineffective. It doesn't even drive the fleas to a different part of the body. You just have an extra collar to move out of the way to comb off the fleas.

Could be so much better

No way this will last 7 months. It keeps coming off breaking so it will not stay on the dog we finally fixed it with wire and fishing line so we have hopes it will stay on now. Has not been on more than a week until it comes off again. Dog still has fleas.

Not a happy customer

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.
