This is a wonderful Australian Shepherd named Apatchy. He's thirteen years old now and getting a bit weak in his back legs. There's nothing wrong with his bark though, as the men building a house across the street could attest.
Apatchy had a sister named Sophia who passed away recently. She was a black and white Springer Spaniel with a wild look in her eye and fur to match. As I don't have a picture of Sophia to post, I'll include another picture of Apatchy instead.
