We're afraid we've got a goat with it. Here's my question. The inflicted goat is about 1 year 3 months old and she has severe diarrhea. What I've read indicates that the disease affects older goats, and diarrhea is not common in goats (it's common in cattle). Is that right and she probably doesn't have it? Also, we've only owned this goat for about 3 months. It also appears unlikely that if she has it, she contracted it at our farm.
