Are you sure-I have always known boxers who look like roxi to be reverse, not vice versa. If i am incorrect then my bad but what 1stboxer described has always been known as a brindle and roxi a reverse.
She is gorgeous! Our new puppy Ginger is a dark brindle, she is beautiful. I really need to take more pics, she's growing like a weed. How much does Roxy weigh? Gunnar, my 2 year old male, is around 75 lbs. He was 2 in January.
