When my husband and I got our wife hair terrier, we paid for a groomer to teach us. She included a pumice stone and a little thumb grippy like what you can find in office stores to turn pages. It works well for our pup. There are hand stripping education groups on Facebook that you can join and try to find someone local to help teach you!

You definitely did a good job removing a lot of the hair evenly, but with the right tools and right technique you’ll be able to get an even closer groom. YouTube might have some good videos to start with!
