I think they're nice dogs, but the woman I know who introduced me to valhunds is such a complete nut that the whole breed is tainted for me.
If you do ever meet one, ask if the dog has a "collar allergy" and if they were able to treat it. The person I know swears up and down that you can't teach a valhund to wear a collar without scratching it constantly. She's totally conformation focused so in frustration I finally said "Male dogs don't like getting their testicles handled in the show ring, but they learn to accept it!" I never heard about the collar allergy again.
She stopped coming to puppy class because it was more important to her that the dog stand pretty in the show ring 7 weekends a year than for it to be well socialized with other dogs and she felt that letting the dogs play in class, then calling them to work and focus on their handlers, was too distracting for the dog. (Ummm. Ooookay.) I really need to meet more of the breed to get the experience of this woman out of my brain!!!!
