Dog Prosthetic

I am creating prosthetics to aid dogs with disabilities. Having a dog with three legs can not only be a struggle for them but it can affect the owner as well. By creating these prosthetics it will give the pet more freedom with ability to move freely without struggle.

To make a prosthetic of your own you will need:

1.5" Wooden Dowel

Paint (optional)

Personalization Tag (optional)

3D Printer

Harness

Glue

Silicon mold

Resin

Foam

Create your game plan to create your prosthetic. This step give the outline to follow for the rest of your project.

Taking measurements of the other paws, the length of the legs, and the body will make sure the prosthetic will fit and be comfortable for the animal. Also using your silicon make a mold of the amputation's site according to the directions. Once the mold is made, fill it with a layer of resin and allow it to cure.

Make your foot and connector of the prosthetic in your choice of 3D design program, I used OnShape. Make these pieces according to the measurements. Upload your pieces to the printer and set the to print. My whole print took about two and a half hours.

Cut the dowel to the correct length and in this part is where any customizations can be made. Glue the dowel into the foot and the connector.

Using the mold you made earlier screw the connector to the resin base trying to keep the leg in a neutral position. Glue the harness into the resin body piece. Fill the bottom of the resin mold with foam.

Get your furry friend and try it out!

Due to time issues I was unable to meet up with a three legged dog for this project which led to some obstacles. I was unable to cast a mold of the body making it so I could not complete the full prototype. If I were to do this again I would have not only a full prototype but hopefully a better working one. This prosthetic I have now will work for what it is needed for it wouldn't be a good long term tool. If I could, the leg part of the prosthetic would be made out of a material that is durable yet can absorb the stress of the walking. This will be more comfortable for the dog.
