My great dane came face to face with a coon a while back (like four months ago) while four of them were snooping around my yard. He wouldn't do anything to the coon but it startled him and it was something new so he gave out an aggressive "woof!!" The raccoon ran backwards so fast up the fence, it was almost unbelievable. I haven't seen them back in the yard since
Best raccoon deterrent that I've ever had!!!
