When he came I'm fairly certain he was pretty dehydrated on top of everything else wrong with him. So I expected a week or so of him trying to balance out - but how long does it really take for horses to balance their fluids? I've been giving him salt in his cubes because he's never had any before (at least in the last 10 years) so he never had salt outside of his grain or what he licked off walls or anything else. So I didn't want to make him sick with too much at once.
My vet thinks he's got Cushings - because of the urination, so I started him on a well-proven herbal blend.
It's been 3 weeks now and he still drinks and urinates A LOT. It's to the point where I am stripping his stall and replacing the bedding entirely every day, I clean it twice a day. Once before bed, but by morning his stall is so soaked he's covered in it. I use wood pellet bedding that fluff with moisture, but it just gets so drenched so fast the pellets don't have time to fluff. The shavings just don't work to absorb it all.
Does anyone know what I should do in this situation? I feel terrible because he has awful thrush and scratches, I'm sure as a result of his soaked stall over the past years. Does he just need more time?
