Hello today i'm going to show you how to make a dog wheel chair for your dog. I got this idea by searching on the internet to see ways that people can enjoy there older dogs more. I didn't really need one cause my dog is 2 but my aunts dog who is 8 now has arthritas really needs one so lets get started.

Step 1: Design

I like to work in AutoCAD, which is a CAD program allowing me to draw everything to scale and easily make changes on the computer. CAD stands for Computer-Aided Design. I have my own licensed “light” version of AutoCAD.

Utilizing this program I am able to get a tracing of the dog into my drawing, and then build a cart to fit him. I of course allow for some adjustment because projects rarely fit perfectly without some fine-tuning.

My design utilizes square aluminum tubing and polycarbonate plastic plate for the main frame. I chose the larger diameter wheels because Nestle is a big dog and he also goes over terrain with bumps and obstacles sometimes. The larger diameter wheels roll over obstacles better and have some shock absorption with their pneumatic (air-filled) tires.

I use nylon webbing strap material to form a saddle, which is looped through slots in the cart’s side plates up top, and heavily padded with rubber tube covered with thick foam padding. I use buckles to allow for strap adjustment.

My new design has a cover over the padding to allow for washing and less slippage of padding on the straps.

The saddle is one of the most challenging parts of the cart for me. Like the seating system on a person’s wheelchair, it is the crucial part that comes into contact with the body and holds the dog in what should be an ideal position. As with human wheelchairs, incorrect positioning can lead to possible injury and worsening of the current condition. That’s the last thing one wants to do while trying to help a dog!

Sometimes an ill fitting cart or saddle will just be uncomfortable for the dog, resulting in disuse of the cart. I like to rely on the owner, along with my observation, as to whether the dog seems comfortable and natural in the cart. They can see the subtle signs and they know their dog better than I do.

After much cutting, drilling and running back and forth to Home Depot a few times, the cart was ready for Nestle to try it out!

Step 3: First Trial

Two major obstacles were readily apparent and would need modifications before delivery of the cart:

Nestle was tipping the cart over sideways as she sped around turns, despite my thinking it was wide and stable enough!
There was not enough clearance to allow Nestle full range of motion for her rear legs, as her legs hit a frame cross-piece on the rearward phase of his leg swing.

To address these issues, I installed longer axles making for a wider “base.” I also angled the axles ever so slightly, so as to tilt the wheels inward, referred to as camber. You’ll see many cart makers that do this, and wheelchairs for people too. It allows one to provide a wider base without going to extremes on axle length or widening the frame.

To address Item 2, I simply moved the rear cross-pieces upward. The frame seemed to maintain its stiffness while allowing lots of free space underneath for his leg swing.

Step 4: Second Trial

I enjoyed seeing Nestle Running and playing again! It must have been like an athlete who hasn’t run in months; the mind is willing but the body needs time to adjust. Well thanks for looking at my TuT and maybe you can make one for your dog to.
