So... Let me get this straight. First of all, you're probably assuming I'll be beating the dog with a stick, far from the truth.So not only is this horribly against forum rules, it's also horrible advice. This is a dog that has injured this person before. Do you really think force is the way to fix it? I'm pretty sure force is only going to escalate the situation.
Brexille's problem's are far beyond what anyone on this forum can help with over the internet. Recommending she get in a physical altercation with a dog that is not above landing teeth and latching on is not only unwise, it's unsafe.
There's one of three things going on here.
1. the problem is the dog.
2. Positive reinforcement isn't working on this particular dog and something else needs to be explored.
3. The application of the training techniques is incorrect. This is not unheard of in any of the training styles.
You decide to lambaste me for suggesting alternate routes - based on an assumption cause we're not allowed to suggest training techniques on this internet forum,..
But people suggest putting the dog down and nothing from admin? Are you serious? Can't get much more adverse than that.
