I see quite a bit of bully breed in Blue – maybe Aussie/bully type mutt?

I wouldn’t say bully; He is beefy, but beefy doesn’t always mean bully. He doesn’t have a blockhead or a square snoot. Someone else said pit mix, and I have to highly disagree and gently remind you, in a non-rude way, that misrepresenting pit bulls is what gets them into dangerous situations.
