When our dog was a pup we had a plastic dog bed with cushion which he did lie in some of the time. Since he's grown too big for it he now sleeps anywhere.. Sofa, floor etc. Although I have washable throws on the sofa, the carpet starts to smell doggy. Is it worth buying the next size bed up or will it be a waste of money do you think? Dunno how he would respond to keep being put in his bed etc. He is home alone whilst we are at work so I'm guessing in those times he would just sleep where he jolly well wanted. What are people's experience of dog beds?
