The poor thing.
I have actually seen in real life a dog on wheels, he was missing his hind legs, and his owner got the wheels, he could run around and everything.
It must be hard for this poor dog on two legs all the time.
It owner may consider a little contraption with two wheels to hold up the dog.
Faith seems to be having a good time, and doing just fine. "If it ain't broke, don't fix it."
I suspose it easy to feel that way, but from the narative alone, it sounds like the dog doesn't know what it's missing, and thinks it's sitation is normal, so why hobble her with a human contraption when its not needed.
God has provided.....
the Will to survive.
