Getting the right size for dog beds is important so that your dog can sleep comfortably. It should be big enough to allow your dog to stretch out or curl up as much as they need. Small round beds are perfect for dogs that like to curl up and mattress beds are perfect for dogs that like to sprawl out. If you have more than one dog, it is recommended that they each have their own dog beds, but if they like to sleep together it is recommended to get them a big dog bed or mattress that they can comfortably share.
Ideally the bed should be placed somewhere draught free and in a warm place in order to give the dog options.
