More: Tuli's favorite pasttime is hiking, hopefully with water involved. She is my service dog and has been working since she was just 1-1/2 years old. Our adventurous lifestyle helps keep her firmly grounded and working well. Tuli has a heart of gold, with not a mean bone in her body, but will still jump into the middle of a dog fight and neutralize it! She's saved a number of dogs that would have been hurt without her intervention. The most amazing part of that is they all come away friends. She's amazing!
