DD and i have both bought these danish design dog beds which stated they are fully washable - but how? Label on cushion insert says do not tumble dry and although we thought the main part of the bed would come off for washing there is no opening to be found! Anyone got any ideas please? Obviously cant dry outside at this time if year!
