Tiny, our wire-haired-terrier mutt dog was a rascal. We got him from the animal shelter in Alaska. Even though he was smaller than other dogs in the neighborhood, he would back them down in confrontations. He wreaked havoc in the neighborhood, causing us to have to pay fines a couple of times because of his activities. As much as I hated to, we finally chained him up. He broke the chains. We got stronger chains and he broke those too. He was just a problem where we lived.
