Everybody wants a dog that minds what they say, doesn't tear up furniture or belongings, only barks at strangers and is perfectly house trained. It's possible, but only with work and effort on your part as the owner. Dogs aren't born being able to speak our language so we have to be able to 'speak dog' fluently to have them understand what we want and when we want it. Basic obedience training helps establish a common language between owners and their pets so that we can communicate our desires to our dogs.
Fundamental training is crucial for a family to be successful dog owners.
Dogs that don't come or sit on command is a dog that may well be a pest and a nuisance to the entire neighborhood. Obedience training is not about teaching dogs to do tricks or competition exercises, it's about training dogs to be obedient and to do what they're told to do when you need them to do it, not when they fell like it. Obedience covers a wide range of skills a dog can learn, including tricks, family manners, show ring exercises, and skills demonstrations. At the same time, they can easily tune out someone calling or giving commands. Dogs do communicate, but they do so in a foreign language to humans.
