EVERY fecking bit of bedding shredded! Not just his, but the other boys' too.
Although they have the run of the house and mostly sleep on sofas/our beds my dogs have hard plastic beds and duvets/blankets etc in the kitchen. This is mainly so they can be with me but safely out of the way of danger and so that occasionally they can be put in there if I'm doing things which are not dog-friendly, such as bleaching floors etc.
As soon as I turn my back Fish has shredded ANOTHER fecking blanket. 
He was renowned for it in rescue and would do it the very second I popped him back in his kennel having cleaned it and cleared out the last pieces of blanket. Right there in front of me, totally ignoring my commands to leave it. So, whilst I'd normally attribute bed shredding to SA, it's not as simple as that. He does indeed suffer from SA and will bark/whine if he knows he's being left, which has to be managed carefully and is being worked on, including me making an effort to be less accessible to him, closing a door between me and him and the other 2 boys whilst I'm at home, leaving him at home when I'm walking others' dogs and taking one of my other 2 boys instead etc.
I can't justify nearly £300 for three indestructable beds as much as I'd like to - DDs would like to be fed and clothed, I'm afraid! So, I need to cure the behaviour. The bugger knows it's not on, I've picked up bits of blanket and done the stern voiced "What did you do Fish?" and he will look totally ashamed, ears and tail down.... and then do it again 5 mins later!
I used to have a regular supply of old duvets/blankets to hand to rescue... now I've run out of any for my own dogs to use! This can't go on, it's a PITA - any tips please?
Thank you. :)
