Thank you all so much for your guidance! Let me give you a quick update.
Desert, thank you for all the help on his diet :)
We've found while he may have a slight case of EPSM he may also have Cushing's. So what he's eating now:
4 hay cube buckets soaked a day (2 quarts of cubes each) 50/50 alfalfa/timothy.
He's getting Bess's Choice for his Cushing's - it's an herbal blend with all sorts of good things for Cushing's horses - if you're interested in it you can read here
. I've seen it work miracles for Cushing's horses and have full faith in it.
As well as a tablespoon of sea salt twice a day. He's never had a salt lick or salt available to him before so I didn't want to make him sick so I built him up on it - I didn't want to give him free choice and have him get himself sick.
He's also getting Nutrena Empower grass balancer, MSM and Brewer's yeast.
Then hay continually throughout the day and of course as much water as he wants.
He's drinking excessively and peeing just as much - I've gone through so much bedding!
The vet attributes this to his previous dehydration (from lack of salt) and potential Cushing's.
As for his legs, I'm so at a loss! I think it's scratches - fungal infection, but my vet says it could be mites. We forgot about it while she was here and didn't think to test him. I've tried washing his legs in Betadine and thoroughly drying them, then applying anti-itch baby powder. The powder I think was a mistake, there was menthol in it which was probably too tingly as the next day he had some fresh scratches. So I rinsed his legs and dried them again, no medicine, just warm water and thorough drying. Then my vet said to try and treat him for mites. So two days ago I covered his legs in Diatomaceous Earth - food grade powder. It's been two days and he's still itchy. My next plan is tomorrow to rinse his legs well
with warm water and dry them thoroughly and then apply M-T-G, another thing my vet suggested if it's actually the fungus not the mites. If all else fails I'll have to get frontline medicine for mites. X.x If anyone has any guidance for that please let me know! I've been throwing my money in so many different directions and I think I need to stop and just let something work, but there are no 'steps' to follow so I'm lost.
As for his feet. His thrush is getting slowly better. I'm cleaning and applying Go-dry and packing his hooves with cotton every day. He's very sensitive.
I can't afford a chiropractor at this point without going into 'emergency' funds. But my friend is a certified equine massage therapist and has given him a couple massages and shown me some great stretches I do for him when I do his feet.
He's been getting turned out as much as possible and if he can't get turned out (weather and such) I take him for quiet walks.
If anyone has any help or any guidance please let me know!
And for your viewing pleasure ^^ my beautiful, most handsomest, wonderfulest boy!!!
