I also live on Siddons Road and I saw a woman and dog matching this description at around the time you're talking about on Friday - I was just getting out of my car near the top of Siddons Road. She'd stopped any abusive behaviour by the time she passed me and was actually quite courteous (I'd stopped to let her walk thorough a narrow gap between lamp post and bins).

I hadn't seen her before (and I've lived on the street for over 10 years) so not sure she lives on Siddons.
