Are there any good websites or hints from you folks on dog training?

We’ve recently gotten a black lab from some friends. She is 1 1/2 years old and is trained OK in the basics (sit, kennel, go), but we would like to train her better. I haven’t had a dog in forever.

Any ideas on what to goggle for free advanced dog training websites?

I am intrested in furthering my dogs training. They have mastered basic obedience and now I would like to take them further. I am not quit sure what I want to to teach them to do but they love learning(and so do I) so much that it would be a shame not to teach them all I can. I am not sure the names of the different types of training or what they include. Any and all info appricated. Thanks!

Does anybody know any good dog training websites?

Do you know any dog training websites?
I’m also wondering if there are any websites with high-quality clips/videos on training. I’m taking a class soon and I am interested in getting a head start.
