    "Works OK"

    I bought this for my dog. It does help keep the flies away and the fleas, but not for long. I end up having to reapply every other day. It does smell good! And yes, it's a bit oily but not real bad. I have figured out that if I spray it on my hand and then rub it in his fur, it's not so oily. I also use a cloth to rub it on him. The directions say to spray it on their coat. When I did that, that's when It was oily. A small amount goes a long ways. I will buy this product again.

    "I love this stuff!!!!"

    this is really great stuff! Yup, it's a bit oily, but not overtly so. It even repels deer and horse flies! I even use it on myself. I love the minty aroma, it doesn't smell like I'm wearing a bug repellent. As for my dogs, I usually spray it on my hands and rub it on their heads/ears as an aide for flies and mosquitoes when we're out for a walk.Works great!

    I needed a product to use on my dog which wouldn't cause an allergic reaction. The product may be effective as indicated but it made my pet so oily I couldn't stand to pet her. Most all the ingredients had an oil base.
