If you're handy with a sewing machine, making a DIY indestructible dog bed can be quite easy, enjoyable and rewarding.
1. Select Materials - buy a 1-inch-thick memory foam mattress topper and 2 yards of washable outdoor fabric. Cut foam to size.
2. Measure and sew the fabric to make a pillow case for the foam insert that can be removed and washed.
3. Add a Zipper to the pillowcase dog bed cover.
4. Assemble the Bed.
