Your wish… our command

All dogs need training.  In fact, proper training and socialization are among a dog’s most basic needs.  And the best way to train your dog is to learn how to communicate with him.  Dogs are highly intelligent and through proper training they learn to channel that into positive behaviors.  Without direction, your dog can become destructive and ill-mannered.

However, training a dog is no small feat – and can seem overwhelming.  That’s where we come in.  We can help you and your pup  speak the same language and set boundaries appropriate to your household and lifestyle.  Once he understands how you expect him to behave, he will work hard to please you, the bond you have will become stronger, and you and your pup will be happier moving forward.

Many new dog owners become discouraged when they realize that many dogs are not naturally the well-behaved, obedient companions that we see in films or on TV. Just like children, they require consistent, good direction and patience to shape them into the pup we want them to be.  Training your dog is not only beneficial for you and your sanity, it has serious implications for the safety and health of your dog, the well being of the people and pets with whom you interact, and the money you will spend on home repairs and replacement footwear.

The consequence of not training a dog can result in everything from annoyance and frustration on the part of an owner to severe and preventable behavioral problems which can result in injury or death to your dog, family, other people or other pets. Whether you already have a canine companion or are considering the addition of a furry family member, remember that training your pup is integral to optimizing your relationship with them and providing them the best life that you possibly can.


There are many different philosophies on how to train a dog.  At A Dog’s World, we focus on positive reinforcement – also called “rewards-based” – training, which is backed by the science of how dogs learn and is the most humane and reliable way to get the behaviors you want from your dog.

Simply put, practice makes perfect.  Just like humans, dogs learn the desired behaviors by practicing them.  He is eager to practice and perfect those behaviors because he is rewarded (usually by food or toys) for performing that behavior.    And, unlike punishing bad behavior, the reward system serves to strengthen the bond and trust your dog has in you.

Each of our classes offer training with this tried and true method.  Sign up today – your pup will thank you!
