This is Gisgo at 6 weeks the day I brought him home. He is an Australian Cattle Dog/Australian Shepard mix. He will be 4 in July. He's never eaten or destroyed anything, doesn't require a leash or a fence, craps only in the woods when we bike or walk and listens to directional commands (forwards, left, right). He's the best decision I've ever made. His only downside is he's afraid of the dark and acts like a prey animal instead of a predator and he requires a ton of exercise (which on most days is a plus).
