It sure is. We used to trim the butt fur on our dog Becki he would run through bushes and get all sorts stuck to it and then bring it onside. Scissors would struggle to cut it, and the scissors would never be the same again. We bought dog clippers, but that made it harder. They were useless.

He's a lot older now and doesn't do the same frolicking so it hasn't been as much of an issue.
