Now his head is almost entirely brown with a black head band. Back is all black with about 2-3 spots of white mixed in. 3 entirely white legs with tan freckles. 1 3/4 tan leg with white paw. LIittle tan mixed with black around tail and black tail with white tip.Chest is white and stomach is white. He is about 2 1/2 years old now.
