I have two German Shepherd dogs (one a purebred and one a mix) and I delight in understanding their make-up. There is a reason they are the most popular breed used in police and military work. Nothing will deter them. They have an inherent disposition that makes them fearless, focused and intent on their mission, and loyal. So, it is with great personal interest that I post this.
Here are three photographs, the first of which is of therapy dogs; the second having been taken in Thailand, and the third having been taken in Vietnam and published in Life Magazine. Unfortunately, I do not know the exact years nor the photographers. For more imagery and info, please visit this website.
