New to the forum. I have a horse that belonged to my mother who passed away 13 years ago, he isn't registered so I can only guess his age to be in the teens. He is exhibiting some strange behavior, always been very lethargic and not too energetic his entire life, but seems to be more than usual. When walking seems to be moving strange, almost like not sure where the ground and his feet are, like he is blind.
He is a paint with blue eyes and they appear to be fine so I don't think it is blindness at all. Not sure what is going on with him, only change is that I sold a mare last week that has been with my heard for 7 years, stalled next to him. Wondering if this could be just depression or is there something more going on. He is eating and drinking normal, seems to have all the correct bowel movements and urinating normal.
I am stumped, this horse is normally very healthy and has never had any problems.
