Its not stupid, Nick-ums. Its what I always do when I've got a sick doggie. It works. Try it, Tony.
Also, have you tried canned pumpkin? Not the pumpkin pie filling, just plain ol' unsweetened canned pumpkin. Something in it is like a miracle cure for diarrhea. I fostered a Saint that had the WORST diarrhea (so bad and icky we thought she had parvo,TG she didn't). Anyway, the canned pumpkin really seemed to help. When I worked at the Humane Society, we gave all of our dogs canned pumpkin when they had the tummy woos. It really works.
One other thing, have you tried grinding up the pills into a powder, and putting it in something? I guess if she's not eating, that wouldn't work, but maybe try grinding them up and putting them in the burger and rice, if you do that.
Hope she gets better!
