This blog has already highlighted the issue of horse fouling v dog faeces, see here.
While information and advice from our followers is always welcome, there is nothing like first hand experience. I am currently on holiday in Cornwall. I don't like to give away specific locations but, Trevaunance Road, you know where you are!
As the sun was shining, I decided to go for a walk. I had to stand out of the way of a large horse as it lumbered towards me. A few feet away, I saw that it had left a significant deposit on the road. I wouldn't normally photograph horse dung (well, OK, I might on a slow day) but this was essential viewing for this blog.
The above picture not only shows a significant pile of horse dung but, if you look to the left of the shadow of my shoulder as you look at it, you will also be able to make out a not insignificant pile of dog excrement lying just by the small grass verge.
The horse dung is directly opposite the entrance to a private dwelling.
If nothing else, this post is here to say: "bad luck"!
