To me, she looks like a pure bred English cocker, her coat may stay the length it is, or it may still grow, her lines just may not be full coated, English cockers do not have as much coat as the American Cockers. My Pye's dam had a very sparse coat, so much so, that she wasn't shown, and she came from a long line of Conformation Show cockers, Pye's Sire is very full coated, and is a Champion of record, Pye's coat came from his sire's line.
I say count yourself lucky if you weren't planning on showing her in confirmation. You won't have a the trouble and mess the rest of us do. I groom my boys every 4 weeks, they are touched up and bathed in between. It's a lot of work!
