I'm concerned now about her geting septic. The pills are working but she made need IMs too. There is no way I could get a vet out on the weekend though unless a horse dying and that might even take awhile.
Something to keep in the back of your mind - check her gums. You want nice pink ones, not pale or white. I'll get out my Vet book and also go pick Bob's brains. Back in a few.
