Vet tested for worm count and will tube for worms next week after a week of hay.
Tested dehydration, which Lad was considerably dehydrated. Lad will most likely loose most of his ears from frostbite (word of warning to horse owners - if you live in a sub zero temperature area, and a horse is dehydrated, it causes cell damage and they will get frostbit).
Lad drank and flooded his stall, they had to move him (see note down further on replacing electrolytes)
He has rain rot and will loose most of his coat.
And he has sores on his coronet bands that are seeping.
Vet scores Lad at a 2, but recoverable.
This is very sad - this is a champion quarter horse.
But right now he is on free choice grass hay. A little bit of soaked beet pulp with loose minerals/electrolytes added, but they are starting with 1/2 oz. a couple times a day. They will start him on grain in 7-10 days.
We have added probios to try to guard against ulcers.
We did not discuss psylium yet as he was in a barn stall that was full of poo, so I don't think he had a chance to eat any dirt or sand.
Thanks for everyone's help. It is hard to see any horse in this condition. And it is unfortunate that this fine animal was found in poor conditions. Anyone who owns and breeds animals needs to realize that we hold their lives in our hands and we are responsible for them. And if we sell them, although we do not have control over their lives after they leave our care, we still hold a bit of responsibility for them. My sister sold the horse, but the people who bought him never finished paying for him, so she still has his papers. It was sad that she had to go through this as she was advised not to sell to this party, but.....
Thanks for the help!
