A little late to update, but I wanted to share Lincoln's experience in case anyone goes thru something similar!

Long story short, I gave Lincoln a sanitary trim that got a little too close. I didn't give him clipper burn, but his fur was so short near his privates that it caused him to panic. If you watch the video, his level of discomfort was extreme. I was so confused because his skin wasn't red or irritated. The problem was, he's too short and stumpy to lick himself "down there". With his fur so short, he was overwhelmed with sensation and it was driving him mad.
People suggested it was Breezy Butthole Syndrome, but I was skeptical. After a few vet visits and time for his hair to grow back...it was confirmed. He had the rare subclass of Breezy Butthole, the dreaded "Windy Weenie".
Something to keep in mind if you have a sensitive pup, and they act similar after a groom!
