Review on Defy Fly Dog Collar Large by Michelle Lyons

Bought two collars for two of my 4 year old bulldogs who were CRAZY GOT FLY; Ears and back are bitten by flies. I have bought numerous fly bags, fly strips, fly pomades, horse fly sprays and nothing has stopped my bulldogs from getting flies other than keeping them indoors. I bought these collars with some skepticism but figured a few bucks more after having already spent hundreds. They say these collars have done their job. Flies in my yard are NOW minimal and flies on my puppies are NO! Flies can fly around, but flies don't land on my bulldogs! So very happy and thankful for this product! Flies may fly by, but DO NOT stop at my dogs! The smell of citronella is not too pleasant and pleasant. The bulldogs did NOT react to the scent, but now I'm worried, the product seems to be running out😱
