seriously, you'll have to catch her in the act before you can discipline her. then you'll have to do some basic training techniques. clicker works, be patient. exercise, mental stimulation, etc. google "clicker dog training" for a start.
cesar's 1st book is his best, all subsequent ones seem to repeat what the first offers.
Crumbs Cindy ... that's a dire situation. Re-washing clothes
Can you use some kind of method to add height to the close line? Or restrict your dogs ability to reach it - enclose a rotary dryer somehow?
Or maybe (time consuming) make your dog aware that it's not a good or welcome thing to do? Like hang any old crap up and then stalk your dog. Everytime she goes to tug something squirt her with a water pistol or emit a very loud, stern 'NO! then when she resists make a fuss of her?
Sometimes you have to physically intervene or remove them from the situation. For example, keep her in the house until the clothes are dry. When my pup was an ‘actual pup’ he loved to demolish the Christmas tree. Solution, build a fence around the tree so that he could not physically access it. Luckily he has since moved on to other things.. . . . . This year we did not have to use the fence; we even gave him his own tree, which on times he would sleep under.
