Tucker is a very lovable 5 year old Staffordshire mix. However, he’s extremely protective (too protective). He has bitten several people over the course of the 4 years we’ve had him. We adopted him from Little Red Dog here in Orange County. We’ve tried to break him from this habit, but to no avail. We simply can’t take the risk of him bitting someone again, but we’d like to avoid putting him down. I’m heartbroken, but I don’t see an alternative.
