From The Daily Mail:
The beloved pooch was born with only two legs and has small wriggling nubs where her front legs should be.
At first Hope moved around by hopping but experts said her her natural mode of moving eventually would damage her bones and spine.
The wheeled device was created by orthotist David Turnbill free of charge with makeshift shoulder joints connected to model airplane wheels.
Each of the device’s ‘arms’ can move up or down independently of the other, allowing Hope to pivot and turn.
The spring-loaded prosthetic arms hook to a custom-fitted chest plate to allow Hope to lay down or sit up without removing the prosthetic.
