I can't find any red spots underneath the black patch. I'm starting to think that it may be the spot where he got his annual shots about 2 months ago. I just don't know.
Has anyone ever heard of clipper trauma or groomer trauma? I was searching online and found a few references to this. It says that if the hair gets clipped too short in one spot, it can create a color change.
This is quite the mystery!!
Thanks to everyone for all your input and advice. This is my first time really posting on here and the support has been amazing!
I hope you all have a happy and safe Thanksgiving!
