Boxer dogs. You better belive it.
Locate the os bone, and carefully grip the base with one hand while holding the prepuce in the other. Pull the prepuce back whilst pushing the os bone forward revealing the glans Keep a firm but gentle grip as you push the glans further to see the bulbus glandis. 4: Begin a gentle rhythmic squeezing of the os through the pupace directly behind the exposed bulbus glandis. 5: With your thumb and a finger, gently encircle the shaft directly behind the expanding bulbus glandis and continue rhythmically squeezing. Continue stimulating the bulbus glandis in this fashion until it is fully engorged. Ongoing stimulation will lead to the full engorgement of the longa glandis as well. I put this together from a few sources. I had to make small edits to the proper technical language to satisfy posting rules.
