I confronted a woman who had a dog on a lead who stopped outside my house. I made eye contact with her as I came out of my front door. She had walked off by the time I walked on to the pavement and as I passed where she had stopped I smelt a freshly left dog poo. It took my breath away. I smelt the poo before I saw it, which indicated to me that the woman had allowed her dog to poo, but she did not pick up the poo. The poo is directly outside my front door and is a health hazard to anyone walking past. Despite my attempts to establish whether her dog had pooed, she did not pick it up and refused to accept I had caught her and her dog out. I did not see her dog actually poo but as the smell was such a strong stench it must have been her dog as I did not see any other dog walkers in the area. It needs to be cleaned away as it is a danger to public health.
