Actually, they all aren't. Our daughter has one (a rescue)and she is a huge nanny to their 2 kids. If someone is chasing the kids (playing) Allie will grab them by the arm or britches or leg - whatever is available - and stop them. Same with chasing her mama (Krisi) Now if a delivery guy or utility guy comes up, they better not swat at her to keep her away. One guy was lucky enough to swat and then be faster than Allie. Krisi will usually make sure she is up away from utility people etc since she is so big and mean looking with all that slobber hanging out of her mouth. She is a big slobbery baby otherwise and loves cats and not for breakfast. LOL
Thanks for the vivid descriptions and insights.
