So sorry to hear it. We're boxer people too and we've had two. Our #2 (Aggie) is about 7 and I'm coming under increased pressure to secure a 2nd.
Your pictures from when she was younger looked so much like our #1 (Ginger). We lost her when she was 9. We are still good friends with her breeder. I miss all the dogs I've had in my life.
