Well first off she isn't half wolf. (; The pure wolf in her is about 3 generations back, her parents weren't even half wolf. Kyra is actually more wolf than dog.
That doesn't make her any more dangerous than any other large breed dog. In fact, she's a bit more safe than most dogs because of the fact that she is always securely contained, or under my control when not in my yard.
Wolfdogs are very...intense in behavior. Wolves are naturally shy of humans by nature, and many wolfdogs inherit that trait. Kyra is no exception; she'd much rather run and hide than bite ANYONE, provided she isn't cornered.
So yes, the "wolf" in her is quite predominant. (:
