bugs be gone!

[This review was collected as part of a promotion.] instructions super easy to understand. my dog didn’t give me to much of a problem applying it to him. he is 8lbs has a slight odor. I also put a cone around him until it was dry to keep him from licking himself. applying once a month to keep bugs away this spring
