I have a 6 month old aussie puppy who has decided be a brat and is stealing stuff and chewing it up. I have her outside most of the day as I cant watch her all the time. If anything is in her reach she will steal it and chew it up. I mean not chew it up a little. More like destroy the item. We are also in a rental right now due to the house being worked out. She chewed up the watering lines and I had to spend 4 hours fixing that. I dont know what to do. I cant keep replacing this stuff. I give her all sorts of toys and things to keep her busy. Such as busy bones...etc. But she wont chew on that, she wants to steal stuff and chew up that. I could be anything she wants to steal. It can be glass jars, food, rocks...etc I go out and tell her No, and take away the item and give her her busy bone. Still she does not get it. I have tried putting bitter apple and things and that keeps her away for a short time. However she some how got a hold of the bitter apple and put a hole in it and the of course It drained all out. She will steal her leash and chew that up as well. She also has started to dig holes and is just messing up the yard bad. I use to let her run free in the back yard. But Now I had to chain her up as I can have her chewing up the yard.
