I don't understand why we have such a large number of penis haters here at YT. All of my furkids male and female, young and old, love to chew. You should see them come running when I call out "Wanna Chew?". They are only allowed to chew in the play pen so I can supervise and be sure that the bully's are thrown away when they get too small.
We are talking clean, muscle here, ladies. And I would almost guarantee that the bit of penis your pup is slobbering over came from a STEER - a boy with no balls to play with. The previous owner of your bully was raised for beef - bulls who are visiting the ladies are way to valuabe to become a dog chew.
And if a brief science lesson is needed, both semen and urine travel through a tube called the urethra so no objectional body fluids come into contact with the part that we are discussing.
Happy chewing!
