I struggle when Ella was not well and wanting her to be outside and enjoy life but sometimes she could not walk. This would also be good for other dogs with health issues. I just saw this idea in The Bark Magazine so I have not used one but a dog trailer for bikes. You can go outside and get exercise and I think Ella would enjoy it. I found this one but it would be for the people in the UK.

Please tell me if anyone has other ideas
