My ND doe has an itchy rear end. Last time this happened was late summer. I suspected worms because that happens to wormy horses too. Valbazen did the trick, but now she is 1 month pregnant (hopefully) and I can't use that. After some research I think I'd feel best about using the Ivermectin paste for horses at the triple dose. My question is, do I need to follow it up in 10 days? again after that? like with the Valbazen. She is 11 months old and has only been wormed last summer. Otherwise she is in great health with loads of energy. I don't want to stress her system. Unfortunately, I didn't deworm her before breeding and didn't expect any problems. And maybe it's something else. Thoughts? I know you'll tell me to get a fecal, but I am in a very rural area! I figured if the wormer doesn't help, that would be my next step.
