How to make an automatic dog feeder

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

To carry out this project you will need very little.

Materials needed.

  • A utility knife for cutting plastic.
  • Marker pen
  • A silicone gun will also be needed.
  • Finally, 2 empty and clean plastic jugs.


It is very easy to manufacture this automatic feeder, see the steps to follow.

  • First of all, you need to cut the upper part of one of the decanters, for this you will make a mark with the marker. The cut should be made just before the start of the decanter curve.
  • 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 was left 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 through which the narrowest part of the first carafe enters.
  • This cut should be made in the flat part of the container, which is below where the handle is.
  • Once cut, check that it fits perfectly.
  • You will then proceed to cut the handle part. You should leave the side of the cover and a finger space between this cut and the previous one.
  • We will also make the lid of the feeder. To do this, you need to mark the first carafe from the top about three fingers apart. Then cut and test that it fits on the outside, like a cover.
  • Clean marker stains with regular alcohol.
  • Put the glue gun on to heat up.
  • Glue a piece of plastic from those cut out above, inside the longest part of the first jug.
  • Insert the food container (bottle 1) into the hole of bottle 2 and stick it with silicone.
  • Wait for it to dry, remove the cover, put the food on and ready to feed your pet.
