Me again ;D I need to either buy or have made a new Kennel for Goldie dog for inside her run. Her current one took great exception to being moved from its original spot and is starting to fall to bits : Id like to get her an insulated one so shes cosy in winter when out there. Any recommendations as to size, type, material? her current "house" is 8ft x 4ft which is maybe too big to be a cosy den? SHould i look at something smaller?
