Well, Whisper curls her tail when she wags it, and Hershey doesn't. Its kind of like a Rottie does with it's tail. Hershey doesn't curl his tail unless he is alert of something.. Either that this pup has a lot of personality! What do you guys think by looking at her pictures?
Charlie had a curly tail when he was a puppy but it straightened out at about 5 months. He's a GSD, not a lab, but maybe Whisper's tail will straighten out???
She's not the best bred Lab though, I know many "AKC papered" Labs (total BYB's) that have curled tails. That and ear set seem to be the first things to go wonky when the breeding sucks.
I agree with Toller, my father's dog is a chocolate lab named Bosco and his tail is curly. His wife says it's because of poor breeding, dad just says Bosco is retarded.
