I got out the clippers, and chose a short guard for the back and a longer guard for the top. Sadly, they were both blue and I accidentally grabbed the short guard first. When I saw how much hair was coming off I knew I had messed up, but there was no going back so I just shaved his whole head. Now he looks like a little army man, but at least it should grow back quickly and next time I will be more careful!!
The before and after
The clippings - instead of just trimming the top a bit, I ended up cutting off 1 to 2 inches. Oops!
