NO! It's too dangerous!
Dogs can be "locked" for up to 20 minutes with no ill effects, so anything less is okay.

Dog locking is simply another term for canine mating. During their mating routine, the male dog's penis swells into what is called a knot. The knot fits behind the female's pelvic bone, and they are basically locked together until the mating it complete and the knot goes back down. That is why you should never pull mating dogs apart. It can injure both the male and the female. Once they start, you pretty much have to just let them finish.
