The horse that thinks it's a dog

I went out for a walk this morning and when I came back, I had seen the tail end of an animal under the porch.  I looked under it and saw this picture.

I attempted to lure him out by letting him smell and taste a small amount of alfalfa.  It became obvious very quickly that he had no clue how to use his back up gear.  He was stuck!  So with some help from another person, we managed to get him out.  He was laying on the netting that was underneath the porch and so that is how we managed to drag him out.
