Would walkers and canes actually be of any use to quadrupeds?
So I'm a huge fan of the show My Little Pony, and while it wasn't extremely common, the animators occasionally showed elderly ponies using walkers or canes. They're typically shown being used by elderly ponies, so I believe the implication is that they need them for the same typical reasons elderly humans need them.
But from what I understand, the main reason why humans need aids like walkers and canes is because we're bipedal. So I feel like a wheelchair designed for quadrupeds would be the proper mobility aid, right?
If they were intelligent enough to understand how to use walkers or canes, would there ever be a situation where they'd be the preferred mobility aid over wheelchairs?
