I could have spent a small fortune buying all kinds of books and videos and DVDs to try and teach my dog really basic commands like sit, stay, and come. But thankfully a friend of mine suggested that I look into online dog training instead, and boy am I glad that I did. I found some great courses online and now I have one of the best behaved dogs on the block. I have to laugh at all my neighbors who have these dogs that bark incessantly and corral at people as they walk by, while my dog just sits calmly.
