Your puppy is still young and learning to walk alongside a wheelchair is a strenuous task to master. Even as an adult, learning this task may take up too a couple of months to fully understand. Take you time in training this and have patience with your pup.
What I would suggest to try and start doing is to begin training your dog the heel command before trying to walk alongside a wheelchair.
After your dog has learned this command you can begin training them to heel by your wheelchair while it is in a stationary position or your wheels are locked. You will be luring your dog back into the correct position on the side of your wheelchair, clicking and rewards while marking the behavior with a hand signal or command such as “Side”.
