Thanks everyone so much!!
As for his diet, as terribly skinny as he is, he wasn't starved, he had been given a minute 2-3 flakes of hay at night (of questionable quality) as well as 1 quart of trotter twice a day. So he has had grain and hay, just not enough and not very good quality. That being said I don't want to change things too fast either. Right now he's on compressed hay as well as alfalfa/timothy cubes - but I think tomorrow I'm going to exchange my unopened bags of hay cubes for straight alfalfa cubes (or pellets if they'll let me). I'll definitely start adding more alfalfa to his diet - thanks Desert (as always!!
) but I don't want to eliminate regular hay all together as it seems to keep him pacified and happy. He's also drinking a substantial amount of water which makes me happy ;) He's pooped a good deal today, each poop getting more like a real poop (not as sloppy as before). I offered him a salt lick (as I don't have loose salt, getting that tomorrow) he ravenously licked at it for a few minutes before I took it away, I don't want him to overdo that either, so I'll let him have it for just a couple minutes every so often - and only so long as he's drinking as much water as he is.
As for his hind end pic, I took it, he was standing at a slight angle, just a little, so the pic isn't perfect. But from looking in person I can say his right side has a bit more weight/muscle than his left. My poor boy with his docked tail ;-;
And just so you can all see him all happy and snuggly
I also just finished combing through his legs with a fine tooth comb and rubbing desitin on all his scratches - his hind heel bulbs were SO sensitive he wouldn't even let me touch them! I just globbed a pile of desitin in each and after that he let me rub it in, it must have really cooled the area, his heel bulbs were REALLY hot. My farrier will look at him tomorrow and let me know what that's all about or if there's something better I should do. It's too cold to wash them, I was told Ivory soap was great for scratches. But I'm hoping by the time it's warm enough for a bath his legs will be all healed up
