We think my Arabian gelding had a stroke last fall...Has this happened to anyone else? He fell over sideways like a tree...It was very scary because he was cast on his back and when he did get up he was very confussed and fearful. He seems fine now but I don't ride him as much. What could of caused it? I thought maybe because he is fatter than he should be, but my vet says no. He also thinks he might have a nuralogical disorder.....But that doesnt seem right to me as he is normal now.
