Puppy pre-school isn't mandatory but it can be very helpful. If you've had dogs before, you understand what it means to take care of one. But whether you really understand canine behaviour and how to train a dog is a completely different thing. I've met many people with no idea of how dogs see the world around them even tho they've had dogs all their lives. So if you think for a second that you could freshen up your knowledge, puppy school is a great idea! I run puppy preschools in Marrickville, Leichhardt and Newtown. My puppy classes in Sydney are focused on gaining practical skills and knowledge to make your life with a dog as smooth as possible.
