A socialized puppy should be comfortable with human touch. If it isn t, it is probably the most aggressive puppy or the least trustful. Either way, you should find one that is both placid but quite aggressive. You need both in a dog. Check out the puppy's breed. The puppy's breed often determines its general trait when it's fully grown. This is an old pattern of dog behavior that is carried over since the dogs were still in the wild. To prevent this, do not play games with the dog that will teach him to challenge you. Roughhouse and tug of war are some of the most popular examples. When the dog starts to nip, it is a signal that the dog have had enough, let the dog rest and do not allow another occasion to reach that point as it also teaches the dog to become dominant. Whether the choice is to go for the pure or the mixed bred, find a dog that matches your energy level, one that approximates your characteristic or one the one trait that you value most. If you have a family, consider the one that will generally match theirs too. Love All dogs love, but some dogs have the tendency to display their affection better than others do. Small dogs do not always make for behaved dogs. As if to compensate for their small size, some small dogs develop tough dog attitudes. Be prepared to do plenty of obedience training to curb their small dog aggressiveness. Mid-size dogs, on the other hand, are ideal for most kinds of keepers from children, adult to old people. You might wait long before you get yourself these dogs, but they are definitely worth the wait, 100% of the time. The Wolf Dog On top of the list is the wolf dog. A wolf dog is a cross between any guard dog breed and a wolf. Wolf dogs do not make loving pets. They are mean, vicious, and hard to train. The idea is to attach the leash the first time associating it with happy occasion or at least occasions that are non- threatening. As much as possible, the leash must never be attached to the dog in ways that will be interpreted as punishment, at least not during the first few times. Initially, the pup will jump, pull, nip, whine, and show fear when leashed.
