Awww! Cute pics, Jo! You're such a proud momma already--I really hope Tank doesn't have owners (at least owners who still want him), 'cause it looks like he's got such a warm, happy home with you and your fam.

Edit: I'm no breed specialist or anything, but do you think Tank is some sort of Pitbull mix? His smallish ears and some of his facial structure reminds me of them
