When it gets to real problem dogs as yours is associate her bad habits with the use of a training collar.

EG when she pulls clothes from the line

You have her tied up,hang the clothes,release her and go inside while in wait watching her..its all about association and she will soon cotton on enough to learn that its a NO NO when she wants to chew the shit out of everything.

Everytime you have her un penned or unchained have the collar on her..I promise you that done properly and with restraint she will toe the line in a very short time.

And before any of the "anti collars" start rambling on about them being cruel, my family pull the collar out during drinking games for some laughs,even running flat out its SFA of a buzz. I even have a pic of one of my daughters taking 'her turn' with it,note she is the one holding her sleeve up ...all laughs too and absolutely NOTHING compared to my electric fences here which will knock you backwards.All of my dogs have learnt the hard way on these fences yet it hasnt fazed them at all.

Surprising enough the girls tolerate it way more than the blokes do haha.

I have three dogs here and on a farming property training is of the utmost need and while it is rarely used now it is there on the hook for re training procedures. I cannot afford to have wayward dogs.
Nothing has convinced my dogs any more than the collar to not chase roo`s or wallabies.

Sometimes that's tough as the dogs do eat `roo`s shot on my licenced permit here at times and they know they are food yet now ignore them.

Once the dog learns that they are no longer immune to your yells, screams or gentle beggings they toe the line quickly.

Here you go having fun after imbibing in the Sambucca
