A few years ago, I used to drive an Equine Chiropractor to one in that area but can't remember the name. I would not have left a Guinea Pig there, let alone a horse. For a start, you could not drive up the lane due to the Muck Heap stopping all traffic. Sagging Barbed and Canada Wire and broken stakes. In the Summer, solid mud where there should have been grass - a seriously nasty environment for horses.
Thank you, This is turning out to be a difficult task, i have searched for tack shops in the area to ask them but cant find any in the area. Just had an idea might to to contact some vets in the area to see if they can suggest any.
