I assume you mean when two dogs are "tied" post-intercourse. If this is the case, then the male dog will be able to push himself out once the penis has un-swollen. This is a natural process and it can take between 15 to 45 minutes. DO NOT PULL THEM APART, since this will most likely cause damage to the male's penis.
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.
