Merlin has been up and down this summer. Some days are really good and he sleeps well, is happy, and goes outside when he needs to pee or poop. Other days he whines, pees in his diaper, and won't relax.
He's using stirrups some of the time now as his feet are mostly just dragging and not trying to walk anymore.
The good news- if you can call it that- is that he seems to recognize now that the cart is what he needs for mobility, and wants to use it when he wants to get somewhere. The downside of that is two wheel corgis in the same house tend to get wheels caught and block each other's way.
