Ah! You're asking just in case...your future pitbull pup barks at another dog...?
That's funny! :lol:
With pitbulls...even those bred for the pit...the idea is YOU MUST HAVE TOTAL CONTROL OVER THE PUP. Your pit pup must worship the ground you walk on...by whatever means works, from the instant he walks into your house. Plus, it will always (for the life of the dog) be an uphill battle. Mind you, it's winnable.
Many can make pretty cool sport dogs.
