I found out today that when a puppies penis won't retract, you can re-sheath by using a cold compress.
I mean, when I was working, I once had to ease a guys foreskin back that had become tight and constrictive behind his bell end and was restricting circulation and I thought that was quite an odd experience but, sliding a dogs knot and shaft back in... never something I ever thought I'd need to do.
But then neither was loosening a tight foreskin with tweezers and some lube.
I had some some pretty unique experiences during my career.,
