If your daughter's interested in getting into Jr. Showmanship in more than 4-H you will need to get a purebred. Otherwise either a purebred or mixed breed will work. A Herding breed such as as Aussie, Collie (rough or smooth), Sheltie, or Corgi (either one) could work as long as you realize that these dogs absolutely must have jobs to do (i.e obedience, showing, agility, herding, etc) and require a lot of exercise. I've had Collies in apartments so it can work but some apartments have size restrictions so that's another consideration. A Whippet could be a great choice if there's a safely fenced area you could take the dog to a few times a week to run. Other possibilities would be a Border Terrier, Australian Terrier, Fox Terrier (smooth or wire), or a Toy Fox Terrier. Yes, I knoe the last one's in the Toy Group but they are terriers through and through.
