Hahaha love this! I'm not sure I could do as good a job as you have with that one line but I love the concept. Particularly though I love how you took human concepts and applied them to dogs. "You ain't no Dog" like he's insulting his manhood/doghood.

Love how you've got the female dog strutting her stuff and intimidating him with a nipple brush. Nice work man! I enjoyed reading it. Thanks for sharing.
