Try it with feather pillows. I wish I had pictures of walking in the room and seeing feathers raining from the sky and two dogs standing in the big middle of them. Thanks, for bringing back all the good memories. Kaila and Cinder have taken out two rogue pillows. I think mine were having a puppy pillow fight though.

Ohhhh, you mean a bit like this?

That's Henry, as shar-pei a friend of mine bred. Poor Henry - attacked by an exploding feather pillow - he-he!
Flynn's technique is a little different - he ate the bottom out of his crate about 2 hours after it arrived, so now I put a blankie underneath the cage so he can't get at it. Before that, anything got shredded and he whittled a good approximation of a sheepskin shape from a square piece of vetbed once.
