I am pondering this with Kola.
He was mildly arthritic, but last year, the safe place he had for just him, 2 acres, and big stall, had horse put in the pasture part. 10 days. I worried about him not getting to exercise, so owner and I discussed opening up big square pen for Kola to be able to get into.
Other horse arrived Thur night. Sun get call, the renter who fed Kola, went out 1 pm and Kola was trapped in hay area because 5 other horses had broken in his stall and beat him so badly the only area on him not scraped, bleeding, or cut was literally his ears.
5 days at vet. And the damage done to his leg now has bowed leg out to side.
I just hate making this decision, and at this point am contemplating whether to haul to vet and let them dispose of remains, or have someone come dig out grave, and putting him down out at barn.
Had he not gotten pinned by other horses? He would still be fine.
Horses make me a better person.
