we have a secure garden 6ft fence all round zola is always on the lead until we get to our place of play the river park etc she is 23 month old and always comes bk when called
If she always
comes back when called, then your either not watching her when she charges people or she doesn't always come back when called.
Either way, leash your dog before she bites someone and they have to put her down and file a lawsuit.
Its harsh, but its the truth. Accidents happen, what if the next person goes to run or kick your dog and her prey drive or defense kicks in and she bites? Are you ready to fight that battle (When she's already getting a name for herself).
Better safe than sorry
