I have a 4 month old Doberman mix. I noticed a while back that there's a bone in the middle of her chest that sticks out quite a bit. I was just wondering if that's normal or if it's something that needs to be looked at. It doesn't seem to bug her but I'm worried about it becoming more of a problem as she grows. She's a mix of Lab, German Shepard, Husky, and Mastiff. She looks more like a Doberman than anything else though. Does anyone know if this is normal or not?
