There has been some debate over this issue. My advice would be to ask the breeder to guarantee that the goat will show Myotonia before it is purchased. The question is often asked if Myotonia makes these goats more susceptible to predators. Any goat will fall victim to a predator if they are being targeted. In our area, even the young calves are fair game for predators.
Many farms employ the use of livestock guardian dogs to protect their animals.
Myotonic goats are quiet animals and are not known to be a vocal breed. I personally feel that the breed evolved this way. However, there are some differences in lines and families of goats which may have to do with background influence of the goat. The different types of Myotonic goats today make this a diverse and fascinating breed. With such diversity in size and body styles, Myotonic goats are a multi-purpose animal.
