Dogwise: Looking for a book about dogs or training? Dogwise is a great resource for books and toys.
Dog Star Daily: Great articles about all things dog and training. A wonderful, lively resource for owners and trainers alike.
Lost Dog Rescue: Wonderful rescue if you're looking for a dog or a cat. We're currently fostering Vixen, one of the 100 neglected huskies seized by the Humane Society International. Vixen was pregnant when she was rescued, and now that her puppies, Donner and Blitzen, have found homes it's time for Vixen to go to her forever home.
The Buddy System: This is a great hands-free leash. I think it's the best way to walk multiple dogs, and I would never run with my two without it.
