Hello:

Yes, that's a dog, but I'm NOT going to say anything else.

It is probably a staffy. Owners like to display their male staffies with a complete set of gonads hanging. It probaby makes them feel powerful.

Dog porn?

OK I'll just say it. There are some people who might see a resemblance to Jesus.

His "likeness" has shown up on cheese sandwiches , trees,
Several kinds of fruits and vegetables.

This is a new one.

This 'Jesus on my dog's butt' has been all over the net.
The power of suggestion does nothing for me; I have my own imagination, thank you.
Looks like the abominabalalalbbbble snowman to me.
