What breed would it be, what would you do with said dog, and where would you obtain them?
My personal first pick would have to be the Karelian Bear Dog, a breed I've long admired for it's courage and striking facial expressions. At left, we have my absolute favourite Karelian stud, Ilo, of Runningbeardog Kennels of Upper Michigan. It's a very nice facility with a few dogs that are well maintained. I would /love/ to have one of his offspring and work it in Tracking, since these dogs do have a very strong sense of smell and a very high prey drive. These are NOT couch potato dogs and are best suited to life with a job. I've met three Karelians in my life, all of whom were in the mountains at my campsite, doing their job and holding the bears off.
Next, we have my second favourite dog, the American Indian Dog, a lesser known breed that has been around for centuries. This dog is a worker and would also do best in a working home. I've always been attracted to their beautiful coat varieties. I haven't yet found a suitable breeder, but would definitely invest in it. I'd like to show these dogs in a more active sport, such as Flyball or Frisbee, because they do have a strong prey drive and a good working head.
Maybe I'm just a sucker for the working/herding types... What do you think? :]
