I did this to Ruby twice. One time on each ear. This happen with the big clippers after the second time I learned my lesson and never used it again. I bought a personal grooming tool for men and it works just fine and is much safer.Good thing I had quick stop both times to puta remedy to my stupidity and a relief on her pain. I So Sorry Ruby. By the way I love coco's toy its very unique unfortunately I can't fit one more in my house.
