My mom used to walk me like this after she dislocated my shoulder when I tried to do a tantrum by throwing myself to a puddle with new clothes, because I would not hold her hand. She regretted immediately and bought that kiddy leash, so I could run freely around her and she would not lose me (because I was also sort of a ninja).
I also had allergies, but it was the case before she put me on leash, so... ¯\_(ツ)_/¯
