Hey, I think my horse is sick but not sure what's wrong. He's normally pretty happy and alert, he's a paddock horse so spends the day grazing. Loves carrots. For the last 2 days he's been really lethargic, he's not interested in carrots or chaff or museli. There was some white discharge coming out of his nose. I think he is a little dehydrated but he isn't really drinking. It is summer here so there is no green grass in his paddock and its 40 degrees. He was in no way interested in me putting the halter on him. Do you think this sounds like something obvious or the start of something serious? I have spoken to the vet who got me to check a few things but had no obvious ideas.
Thanks for any ideas
