Possible choke and ongoing symptoms
At the moment I have one of my horses on stall rest recovering from an injury. My other horse is being stalled at night to keep him company then is out during the day in the paddock.
Yesterday I fed them in the afternoon, fed the invalid down at the stable and put the other horses feed down for him in the pasture. The horse eating in the paddock suddenly came tearing down to the stable and stood there coughing and drooling liquidy feed. He was hunching his neck back and looked quite uncomfortable. I watched him for about 10 minutes then he shook himself and went back to eating grass. When I picked up his feed bucket afterwards it was still mostly full.
Seemed fine today and ate his morning and evening meal with no problems. Put him into his stall and he did a small drool but no coughing or hunching. Then he passed a massive amount of manure which looked normal but he was grunting and straining as if it hurt. Watched him for awhile and he then started eating hay as normal.
Any thoughts on what might be going on? The vet is coming out at the end of the week to check my other horses progress but I will move the appointment forward if this continues and get him checked as well.
