My Dog Saved My Life Wyatt is a medium sized dog. He is a black and white mixed breed. I adopted him from a shelter when he was a puppy. Groomers and vets have told me they suspect he is part schnauzer and part terrier. He loves to eat any kind of food that comes from a noisy bag. You can even put regular dog food in a rattly bag and he thinks it is a treat. He is housebroken. He can sit, lay down, and roll over. About four years ago, when Wyatt was just 3 years old, I was at a the lowest point I had ever been in my life. After much anguish and heartache, I had decided to take my own life.
