A WONDERFUL resource I've found is the website of YouTube videos by a dog trainer who goes by KikoPup. She has oodles and oodles of videos that show how to train a dog using positive, loving treatment. I started clicker training with Sophie because of the KikoPup videos, and it's going great so far! PetSmart sells clickers for around $2, so you could pick one up and try clicker training with your new furbaby. Here's a link to KikoPup's site
