As the title states I'm the owner of a German Shepherd puppy. I want to train him early as I possibly can and to do that I need a regimented guide to it. The dog is going to be massive but for now it's a little nipper (see attatched picture). I am looking for tips that teach the most discipline a dog can learn. But I also want the dog to always feel loved and at home. Thank you in advance for your time and please refer me to any books e or otherwise that i can read to gain the knowledge I'm looking for.
