I remember when she was this age (5) and thinking she was old. GSDs are seniors at 7, and I felt like she was aging too fast. I thought her face was so white. She started greying at 2 and eventually almost her whole face would turn white. Looking back on it now, she was so young and fit at 5. She was in the prime of her life. People would ask me if she was a puppy (probably mostly because she was so small) up until she was about 11. I had no idea how long she would live, and how well she would do up till she hit 14. It was unbelievable, really.
