The colt has had troubles breathing for a little over a week now. We gave him 3 days of shots, 10cc's each but, did not see any improvement in his breathing so we discontinued the shots as the mare is unfriendly and it was a major hassle to get them separated. He had been maintaing high energy and playfullness but, today he is wheezing more than before and is very listless. He would not stand up for quite a while when I was trying to let them out of the barn. He is now up and is following the mare around but, he sounds just awful and appears very week and disoriented.
Any tips/ideas on what this is and how we can help him? We have spoken to a vet who stated that he must have an upper respiratory problem but, what are we supposed to do? I do not want to stand by and watch him die. I want my playful little buddy back.
