If they don't carry it, they can probably tell you where to get one or maybe even order it.
People call those devices dog carts (which also applies to a cart pulled by a dog), or dog wheelchairs (but they don't sit in it, so it isn't really a chair). Wags doesn't sell them. There are only a few manufacturers nationwide, and they all sell via the internet. Some will also do fittings at their shops if you live in that state. Some good manufacturers include Walkin' Wheels, which is cheap but adjustable; Eddie's Wheels which are expensive amd heavy, but custom fit and durable, and Doggon' Wheels (probably spelled wrong) which are custom fit, but less so that Eddie's, and they're lighter and easier to get your dog in and out of. My paralyzed dogs had Doggon' Wheels and they worked great.
Sadly, we are all just shoppers there. Your question is ever-so specialized. I would call them ((541) 338-8801). They are all very friendly, ever-so helpful and impressively knowledgeable.
They don't carry them, but their place is big enough to accommodate them if you use their services. They are amazingly friendly and they care slot about the animals
I don't recall ever setting one but they could probably direct you where to go
Google "wheelchair for dogs"
I'm not sure about that. I'm sorry
