How to make an automatic dog feeder

This automatic dog feeder is very easy to make at home. The basis of this project are two plastic bottles that we will turn into a feeder for our dog. You will have food for 3-4 days.

To complete this project you will need very few things.


Materials needed.

  • A cutter for cutting plastic.
  • Marker pen
  • A glue gun will also be needed.
  • Finally, 2 empty and clean plastic bottles.


It is very simple to make this automatic feederlook at the steps to follow.

  • First, you need to cut off the top of one of the bottles, for this you will make a marker mark. The cut should be made just before you begin to shape the bottle.
  • After marking, proceed to cut out this part, you will have part of the handle still attached to the container.
  • Mark the part of the handle that remained and cut to remove it.
  • On the other hand, you must take the second carafe and place it on the side where the handle is, mark to make a hole where the narrowest part of the first carafe enters.
  • This cut should be made in the flat part of the container, which is below the handle.
  • Once cut, check that it fits perfectly.
  • Next, you will move on to cutting out the handle part. You should leave the side of the cap and a finger space between this cut and the previous one.
  • We will also make the lid of the trough. To do this, you need to mark the first bottle at the top about three fingers away. Then proceed to cut and try to fit it on the outside, like a lid.
  • Clean marker stains with rubbing alcohol.
  • Heat up the glue gun.
  • Glue a piece of plastic from those previously cut, inside the longest part of the first bottle.
  • Insert the food container (bottle 1) into the hole of bottle 2 and glue it with silicone.
  • Wait for it to dry, remove the lid, place the food and ready to feed your pet.
