well mule deer, mt goats and elk can all transmit MOVI to sheep. The odds that someones packgoat transmits MOVI to a wild bighorn sheep is minuscule at best. It would mean that your goat would have to have MOVI. Then that goat would somehow leave you and find a bighorn sheep and touch nose to nose. Most pack guys are doing there part with their goats and testing their herds.
Lot of mis information in this thread reading all of it lol
