I'm visiting north Yorkshire (North York moors national park) currently. A couple of times I have driven past a pony tethered at the side of the road. I can't see any food/water source. To my (untrained) eye the pony looks quite frail/unkempt. I looked on the RSPCA website ( no help). Where I live in the south I know of a local charity that rescues abandoned horses and they are the sort of people I would normally contact. As i say im visiting here so wondered if anyone on here was local and had any suggestions.
