I always have one near base but I will get it to 90% in taming then it gets shocked

When startled: DAH! OOO-OOO!
When killed(extremely high pitch): DAAH!
When Normal: OOO-HAH-HAH! HU-HU!
When Tamed (low pitch): OOO-HAH-HAH-HAH!

Try to practice with berries before wasting kibble

If you startle it alot it will have a heart attack and die no matter how high the hp is
