You might be nervous to purchase one of these at a Salvage Yard, but let me assuage your fears. This is brand new, completely free of all smells, residues or other dog waste hazards. There's even protective wrapping on the can flap and bag dispenser roller! Tuck it in your backyard or put it on the curb and become a smashing hit in your neighborhood. You will need a key to replace the can liner and bags for this, which you can snag on this website for $4.
