Things You'll Need
- Scissors
- Empty 2-liter bottle
- Flat tray no deeper than 2 inches and no wider than the 2-liter bottle
Instructions
Wash out the 2-liter bottle and remove any plastic labeling. Make a diagonal cut in the top of the bottle, leaving a 1-inch slit near the top.
Fill the bottle with dog food, taking care not to fill it past the opening you have just cut.
Turn the 2-liter bottle upside down into the tray. The food will pour out, forming a pile that will support the bottle in this position.
