Some of you have been blessed to know Terriers. Some have not. To put it simply, they are hunting dogs. They are smart, they are determined, and they are amazingly tenacious. For example, if you take one from their home without their consent, they can be most vocal in their disagreement with your actions. They might even throw themselves against the walls of their crate in an attempt to make you lose your balance. Determined? Very much so.
