Today, I can happily tell you that I was told that after he receives his final dose of medication tomorrow, he'll be able to go home. I am very happy to have his discharge papers in hand! However, there is still a very long way to go.
Over the past ten days, he lost a rapid amount of weight. Even when he was receiving so much food at the vets.This means, that he needs to put this weight back on.
All his test results came back inconclusive, so we're going to take a shot and treat him for extreme gastric ulcers (Please note: We've looked into this before, they believe they're in a place where not 'easily' seen). This means he'll be getting daily oral medication. Along with this, I've been taught how to check his heart rate and keep an eye on his gut sounds daily. This, along with his weight have to be carefully recorded.
His only allowed to eat hay and grass. And, a lot of it. He needs to be eating literally continuously. LOTS of nutritious hay to munch on for the pony. For at least the next two months, nothing but hay and grass will be fed to that horse (except for a weekly bran mash). After this, we'll discuss what graisn are suitable for him. For the rest of his life we will have to be very careful with food though.
Finally, no riding for over a month. No competing for at least two, I'm allowed to take him for light walks - but no hard work.
While it seems like a very 'basic' outcome for such a major sickness. We're going to hope it works, otherwise - back to square one.
