Pittie Mix? My not just Pit Bull Mix? Or "He's a Mix" or "He's a Mutt"?
This breed does not deserve to be demeaned with such names as Pittie, Pitters, pit bulls, and all of that other nonsense.
I must say I DO agree with that.If you dont want to spell out American Pit Bull Terrier then just say APBT or Pit Bull.
