When your puppy comes to you, don’t reach out and grab him. This can be confusing or frightening for some dogs. If your puppy is timid, kneel and face them sideways and offer him treats as you reach for the collar. Never call your dog to punish! This will only teach him that you are unpredictable, and it is a good idea to avoid you. Always reward your dog heavily for responding to his or her name, even if they have been up to mischief!
If your pup barks: Some dogs have the habit of barking at other dogs while on a walk. Oftentimes, this behavior comes as a result of lack of exercise. Make sure your dog gets the proper amount of mental and physical stimulation for his age and breed. If this is still a problem, use the same process as you would if your dog is lunging, as described above — create distance and offer treats before he starts to bark, so every time he sees a dog he gets used to turning his attention to you.
Just as a child needs a caring parent; an athletic team needs a coach; your puppy needs a leader and a clear social hierarchy. If you do not take up the role of leader, your dog will; and you will end up with an unruly, disobedient dog. Many people try to win their new puppy's love by letting the puppy always have its way. Buckets of affection is a wonderful thing for most puppies, but it must be tempered with respect.
