You do realize how dumb that sounds, right? Dogs thrust quite vigorously. Dogs also lick their own dicks. You ever feel a dog's tongue? I wouldn't call it perfectly smooth. Not as rough as a cat's tongue, but, there's a good bit of texture there.
If you have a dog try to lick a severe sunburn, that would likely hurt.
Why is it, that canines don't recoil in pain whenever they lick their own penis? Or you touch them? Because it DOESN'T HURT.
