"Mucousy, slightly blood tinged tinged stool" sounds alot like Giardia. When my dogs got that, they refused to swallow any treats with the prescribed medicine, so I looked up online & discovered I had 3 natural things at home, each one known to kill Giardia. So I began giving them a doses of all 3,2x daily, along with an extra meal to put their weight back on with ... and they were free of symptoms right away, & back to full weight by the week's end! (Our 70 lb. Rottie had lost 10 lbs.)
