I have also made a dog quilt...two actually for our American Bulldog grand dog. Both are rag quilts with the frayed edges. They have been washed weekly and they are still intact after ten years for one and five for the other. I did repair the top and backing on the first one as the fabric became worn on it, but not the batting. Now I will tell you that I used Warm and Natural batting and it held up beautifully. I think the skrim and the fairly close meander made all the difference.
