Poorly Hog

This young chap came to us last night very dehydrated and passing blood in his stools. He is taking fluids , but appears to have some sort of infection which is being treated with antibiotics.
When he first arrived he was very thirsty, he would walk around the cage and just suddenly stop and fall asleep, then wake up and continue walking then stop again.
He's not out of the woods yet and we're keeping a close eye on him.
