A bit of a strange one! I have two dogs and they like 'making fluff' as we call it i.e. pulling the fluff out of their toys and spreading it round the house. One is about 4 months old and she has a duvet in her bed. She chews holes in it and spreads the fluff all round the place. Ok she is just a pup and having a bit of fun. But my 3 year old inexplicably just started rolling round on my own bed chewing the duvet she hasn't done anything like this before! Is this normal?!

She's probably seen the pup do it and thought 'ooh that looks fun, and she's not getting told off for it'

I'd lay down the law for both of them beds= no

Otherwise you'll be having issues of Marley and me size later on
