    I guess I’ve been very lucky for the last 40+ years. I’ve never had flea issues with any of my dogs but for what ever reason this year it all changed.
    With all the negative reviews on “all” the flea collars sold on Amazon it’s really a crap shoot on which to choose. I opted to go with the “Seresto Flea and Tick Collar” probably because it appeared to have the least number of negative reviews.
    Bottom line (despite all the negative reviews) this collar is working fine for my 10 1/2 year old Chocolate Lab and with no apparent side effects after the first month of use. I’m only one user but that’s my experience and honest review.

    Seresto is an excellent collar but I have one problem. I’ve always used this collar on my dog ever since he was a pup. He’s 5 now and 130 lbs and the collar no longer fits sound his neck properly. He’s a large breed and has a large head with a thick neck. Now the biggest collar no longer stays around his neck, I love the way it works that’s why I keep purchasing it for him and my girl..I try to tighten the collar as tight as possible without choking him but it always finds a way to slide off.. Other collars are long enough but they just don’t work like the Seresto collar.
