my dogs sleep on the "oops" and "oh my" quilts that didnt turn out the way I intended...I made each of them a square bed, using heavier fabrics, and then the quilts go atop that.......so I can pick the quilts up, wash them, and I have several, so I can change them out to be washed........my biggest dog is 119 pds, so that took a big one..........the middle dog is abou 65 pd, so medium for her, and the smallest one is about 35 pds....just kinda measure your dog when they are lying down, and then you will know about how long ad how wide it needs to be. I stuffed these with a combinaton of small scraps and batting.............
