All hunting dogs are hyper. My pup will chew everything in sight if I don't take her running.
Llewellins areenglish setters, like Tomko or Ryman. They have a their registry in the American Field's Field Dog Stud Book (as opposed to AKC) simply because of timing. They dominated field trails in their hayday (1900's) but now known as a foothunting dog. They have to be DNA tested to be registered so breeding is alittle more strict. Other than that, they are no different than an english setter, Ryman or otherwise. Here is a pick when she was younger.
