I purchased the large, Cerulean Blue, Oval Red Dog Company bed for our Dusty's 4th birthday. It was expensive compared with her usual beds but it was for a special occasion. It came already built unlike other beds with have bought in the past. I must say it is beautiful and very good quality. It is made of wool to keep her warm in winter and cool in summer. The base is so soft and fury. It springs back to shape like a memory foam mattress. Dusty loves it as you can see from the pics. She is a 35 kilo German Shepherd and there is plenty of room for her to curl up in the large size. I would highly recommend The Red Dog Company beds for your pampered pooch!! Money well spent on our girl.
