Look pathetic when it's empty and joyful when it's full of food.
Create attractive fringes and de-stuff those "indestructible" toys.
Some thoughtful arranging will make an eviscerated toy resemble roadkill but with no blood to mar the carpet (blood on the carpet gets you yelled at).
When it's time to freshen up the decor, rip off those old bed covers to induce the human to make new ones.
These are just a few, simple ways to keep your home looking dog-friendly for Naughty Terrier Day.
