Indi is 7months old and yesterday he discovered "making" his bed. We use a king sized comforter folded over 4 times to make the bed for his crate and just yesterday he figured out that if you dig at the edges you can make a nest, then put all of your soft toys in the hole, select a few chew sticks to hide in the folds, and bring your most favoritest chew stick in the middle, where you sprawl out over the toys and blankets.
I wish I had my camera.
What are some of your favorite doggie revelations
(my second favorite was when he discovered sniffing stuff that was fun)
