Question
DO bulls have bone or cartilage in their penis?  I have been told dogs do - is this true?  WHat other animals have bone or cartilage in their penis?

Answer
Hi cath;
Yes they do.  Most mammals have a bone in the penis including dogs.  In fact a walrus has one that is up to 30 inches long. Primates have them except for humans.  They have been lost in men.  These penile bones are called Bacula.  
This will really blow your mind.  Go to www.skullsunlimited.com and you can buy one for a few dollars. They come from many different mammals. They are called "hillbilly toothpicks" and are you ready for this? Some people use them for coffee stirrers.  I kid you not.
A gift for someone who has everything.
