Dog attack - part 2

I had to get New Years Eve tickets today from out local ‘dog friendly’ pub. Tommy doesn’t go there very much because we only normally go there at the weekends when they have bands on. It gets very noisy. Anyway, off we went today and I stopped for a half with someone I know. We got chatting about Tommy and I mentioned that he was very good with other dogs, but now after the ‘grab the head’ incident is a bit more wary of dominant ones. I explained the incident and a lady said ‘oh really. Was he being walked by a man with dreadlocks?’ ‘Yes’ I said. ‘I saw him a few weeks ago with him walking past the café on the corner. The dog picked up a small white dog then and shock it violently. The poor mite was bleeding by the time the dog dropped it. I ran to the hairdressers and got a towel for it’. ‘Jes! What did the guy walking the dog do’. ‘Oh nothing. Just disappeared into the flats’. ‘What about the owner of the dog’. ‘She took him to the vets as far as I know. I gave her my number in case she reported it to the police but I haven’t heard anything.’ I haven’t reported it either. Maybe I should.
