Been treating a goat for a while now becaus she had bottle jaw over a month ago. Her bottle hasn't returned, but her eyelids haven't changed back to pink. Today, I got to see her poop, it had worms in it...Never seen worms in her poop until just now, and I HAVE been looking, because I am used to dogs and their worms showing up in the fecal. How come my wormer isn't working? After a month wouldn't ANY worm be gone? What kind of worm is this? I am treating with Valbazen.
