Bob's seems to stick out pretty far. Further than Joey's anyway. I had noticed it, but I had not asked the vet about it. She has seen Bob and never mentioned it. It does not seem to bother him either. It is hard to tell the difference between the two visually because of all Bob's fur.

I am not sure why that is. Maybe it is just a difference of genetics like weight and height.

It is a good question, maybe someone like Jen will know.
