Not much. It is harder than a tennis ball when the erection is at full strength.Are real knots at all compressible? (Without harm of course)
Can you point me in the direction of this article?there is some information in the articles & blogs section that can help you.
A dog's penis has a bone it in so the firmness will be quite different from a toy. There are other differences, but the articles section provides that
Oh boy, I just got myself a GSD pup, and if his sire is any indication of how big he will be then he will be huge, I hope I can manage his knot when the time comes.I have only had medium toys and dog knots are harder than that. They are very hard. Dog knots don't squish or deform if erect. They might make a small indent to conform to a finger that's pressed into it but the knot shape will stay the same.
That still sounds pretty firm, I sincerely hope that my boy isn’t too large for me, but I guess only time will tell.They feel hard but not totally solid; they give way a little when you squeeze them kinda like what a bouncy ball feels like, except bigger obviously.
