What owners say
It really works! Lasted 4 months!!
This really works. I ordered this in April for my 2 small dogs( Bischon Frise & Shitzu/yorkie mix). It is now September and I am just having to purchase a new one. They got their first flea literally last week. I can’t believe the collars lasted 4 months. My backyard is huge and surrounded with so many HUGE trees. Great price for the quality of protection. Do not hesitate to get this to keep your fur babies safe.

It works!
It works! I put a large Seresto collar on my German Shepherd and a small on my chihuahua. No fleas at all a few ticks here and there on my German Shepherd but nothing major she is an outside dogs and is friends with the stray cats so a few ticks is to be expected. No smell easy to use no side effects the collar stays on.
