Feeding your dog can be a drag, so make an automatic dog feeder that will supply food to your dog while you are away. Even if you never leave your dog for more than a few hours, a nifty dog feeding machine will save you time, which you can spend playing with your dog. A simple gravity fed dog tray that uses recycled materials will help reduce your waste as well as save you a few dollars.

Wash the milk jug thoroughly with soapy water. Any tall plastic container will do, but a gallon milk bottle is an ideal size and is a useful way of recycling and cutting down on trash. Rinse the bottle with warm water until it is clean and soap-free.

Cut a rectangular window at least 4 inches wide and 1 inch high on the bottom of one of the jug's wider sides. Aim to cut the window as close as possible to the base of the jug. This will reduce the amount of food stuck at the bottom of the jug when the dog food runs out. If your dog's food comes in big chunks or there will be a few dogs using the feeder, make the window as large as you need it.

Fill the jug with dog food. Depending on the type of jug you are using, it will probably be easier to fill the jug through the rectangular window you cut out. If you removed the jug's cap, replace it. This will help keep the food fresh and protect it from insects.

Place the jug in a tray with sides 2 inches or less high. The tray's sides will contain the dog food and provide some resistance so all the dog food does not spill out at once from the jug. This dog feeding machine is a simple gravity fed machine, which will supply your dog's food slowly.

Tape the jug to the tray. Wrap the tape around the jug a few times for extra strength. Don't be stingy with the tape use enough tape to give the jug and the tray a strong bond.


  • Some dogs do not know when to stop eating and will eat until they are sick. If that describes your dog, limit the amount of food you put into your feeder.
