There are plenty of books teach you how to train your dog yourself. They are usually in librarys. You can also learn online - some websites are free. Training your dog yourself is probably the best way, because it will create a bond with your dog and yourself also, it will be for FREE. Although, it may not be as well done as hiring a trainer to actually train your dog, but you said you wanted it to be free.
