I was entrusted with a 3 or 4 yr old ( so I'm told) stud that is supposed to be a Tennessee Walker. He has been in a 40 acre pasture for the last few months with a mare & 2 gelding quarter horses. 4 days ago my father-in-law noticed that Midnight had dropped alot of weight. They brought him off the hill & put him in my barn. I was astonished at how thin he was. I had not seen him before. Anyways, he is very unsteady on his feet. The owner, my brother-in-law, is contacting a vet to come out & look at him. Where we live, there aren't many vets & getting one to your house is quite a problem. I immediately gave him a dose of wormer and started feeding him a 2 pound coffee can of a 10% feed (with a low mollases content) and alfalfa pellets mixture twice a day, along with hay & plenty of water. I noticed his eyes had a cloudy white glob in them that I was able to wipe out, but it is back again. Also, today he layed down & we had a tough time getting him up. He tried twice & fell over. The third time, he made it up. He's very wobblely on his feet & he's not very enthusiatic when he eats, although he usually does eat all of his grain. I was told he's not been cut, but in his testacle area, he has a very large ball that feels like a very full water balloon. When he urinates, it's a very small stream and not alot at one time. It drips for several minutes when he's done. We have noticed that he does urinate quite often, also. He's water intake is alot more than the output.
For being so young, he's not active at all. He reminds me of a very old horse. I contribute that to his poor condition. I'm afraid he is not going to pull through & I'm asking for all the advice I can get. Thanks in advance for your time & support.
