Choosing a Wheelchair for a Dachshund

Hi everyone, I was wondering if anyone here has dealt with something similar. Our dachshund has started showing signs of rear leg weakness - it’s getting harder for her to walk, and the vet suggested we start looking into a dog wheelchair.

My husband and I have been doing some research, and we came across a brand called Furria. Here's the link, in case it rings a bell for anyone: https://furria.store/products/small-dog-wheelchair
Their wheelchair costs 109 pounds, which is a bit of a stretch for us right now, so we’d really appreciate any feedback.Has anyone here ever bought from them? Are they trustworthy?

Thanks so much in advance!
