spot on :thumbs: :clapper:
from personal experience, the police would take no action against you in those circumstances, a statement is all they'd be after and say frightened, not aggressive.
briefly, i had a rotty on lead and in control, woman had terrier off lead and very uncontrolled i asked her to put it on a lead but flossy was having none of it, flossy ran at the rotty, growling rotty picked it up and threw it, minimal damage, a slight tear on the shoulder. i had police question me and in their words, 'it was dog to dog agression and they weren't going to get involved'
