This mare was not.
I found out about this yesterday. It is unknown whether the horse was turned loose or whether she got out but even if she wasn't dumped, just look at her apalling condition. And she got caught in the cattleguard - 3 broken legs, yes she had to be put down on the spot. By the way this was in Tonopah and the pictures were taken by someone I "know" through my riding forum.
It just makes me want to shoot someone.
This is happening more and more. This is why, despite a huge decrease in our income, I still have 20 equines. It's heartbreaking to see this happen to ANY horse. If it happened to one of mine, it would kill me... so if we have to eat Top Ramen so we can feed our herd, well, so be it.
