My rescue colleague Anne Rogers (who has the most gorgeous giant of a shaggy dog herself!) has created a really nice training site and has a whole slew of useful downloads on everything from preparing for a puppy to training basics and all the most common behaviour issues (leash pulling, etc). Very handy as you can go and download what you'd like.
