Any breed of dog can be taught to be a good obedient dog unless it's mentally ill or abused beyond repair
but you must be the strong one(alpha) if you cant do that you may well end up with an out of control animal.My dogs know who is boss in this house and it's me.DH just doesn't understand them like me
And it does not take a heavy hand but tone of voice and also alot of bonding and consistency.
I also really believe that the vibe in the house is the vibe in your pets if there is alot of screaming and fighting in a household it totally affects the pets.Our house is about peace and kindness and the dogs pick that up.
And yet the dogs know they better be good no mean stuff.
