Hello,
Eragon has gotten more orange. I am sorry that he still is not feeling well.
As far as the reptaid, that would be fine, it would probably boost his immune system.
Do you know if they did a fecal float? Traditionally that is what most do, but that doesn't always register everything.
I would get another fecal done & request a fecal smear as well. I agree with the above poster.
Giardia, as well as amoebas/flagelletes are a lot of times the cause of a greenish & mucousy stool. Do you use filtered water?
Do you wash the greens really well also?
The medications for the giardia would be different than for worms & parasites, too.
