Damn...I like that...I will be that guy...LOLI can't imagine it being that difficult. I've trained dogs and it's all about programming.
If you shaped something with a similar look and consistency to a cock and balls, like a sausage with two smaller meat bits for the testicles, then tied it to something like a cardboard picture cut out of a man and made the dog get used to tearing it off to eat it everyday, it could be quite a simple thing to instill.
I can imagine that in a scenario where the bitch was presented with a real pair of male genitals flopping about in the same way and at the same height she's used to, that the dog would succumb to it's eating habbits.
Knowing how dogs get even more excited as you yell when they are attacking, i can imagine that the first scream of agony from the man following the realization that his prized penis and balls are in the jaws of a hungry beast, would be promptly followed by an even more ragefully ravenous dismemberment by the dog.
How cool would it be if after the dog successfully disconnected the testicles and penis from the body with her sharp teeth, it's head shaking from side to side, that she didn't chew or swallow... but instead obediently walked away from the ********* body with what was left of the victim's male pride in her mouth. Walked a little further to a dark lit corner of the room and placed what was left of his testicles and cock on the floor, at the feet of her female owner whom had been secretly observing the whole event as she played with her pussy in ecstasy at the site of her dog completely destroying his manhood. Just like a good dog retrieving it's fetch. Maybe she could then user her bare girly feet to make sure that the balls are both popped as she rubs her self, and after she orgasms, she can treat the dog to what's left of the penis as a good doggie reward : )![]()
