So apparently this is a sub for breeding fish?

I've been searching for a sub to get information on breeding sheps. I've got a "pocket" sized pitbull that is a great "pocket" herding dog. I'd like to try my hand at breeding her. Do pitbulls count as fish?<br><br>Edit: I'll be using my pitbull as the "bitch" and a sheepdog as the "stud"
