I guess this is only purebred specific (unless you have a breed standard written for your mix, which would be absolutely fabulous) but is your dog easily identifiable as a member of it's breed? Are there certain qualities you think of that make up a breed? I'm not talking "this is a show dog, so yes" or "this is a field dog, so no." More like... ESS typically have rounded/triangular shaped ears (although in a show groom, you'd never know). Buzz has big, thick, round Welsh Springer ears. Or ESS are usually in the 40-50 pound range, but Bailey frequently hangs out below 40#. ETA: the other significant factor in Bailey being under 40# is that she's taller than most other bitches (at the top of the height standard at 19.75"). Most 40# bitches are around 17-18" generally speaking.
