If you have ever stood with your mouth agape while your dog has abused houseguests in one comically absurd way or another, then you understand the importance of dog obedience training. Poorly trained dogs are not only embarrassing, they can become a legal and social liability if their behavior is allowed to get too far out of hand. Setting boundaries and guidelines as soon as your puppy comes home will keep him from causing issues later in life. Some behaviors, once they start, are nearly impossible to break, and can range from poor toileting habits to jumping on new people or worse. Get the upper hand from the very start or you might find yourself sitting home alone with your dog far more often than you really want to.

While I can't say this about ALL obedience schools, I've found that the couple I've experienced have been overly expensive and not gotten the results I'd hoped for at the price they charge.  If you have the time, I recommend doing it yourself. 

With a small price tag, a 60 day 100% refund guarantee, and  a whole ton of extras, I recommend checking out this site to put you on the path to getting a 'good' dog.
