No. but I sympathise with your concern as I have also had a few dog incidents with my child in tow. A few weeks ago a large dog took more than a comfortable interest in my young child in the Horniman Gardens, down near the old paddling pool area, and started to run at her, barking with its lips curled back over its teeth which I think is not a good sign. I had to lift her up and run fast. It was pretty scary. Dogs and children do not mix, whatever people say.
Good luck in reporting it and getting something done but I suspect that the legislation is pretty weak when it comes to seriously addressing the problem.
