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.
It typically takes 4-6 months for a puppy to be fully house trained, but some puppies may take up to a year. Size can be a predictor. For instance, smaller breeds have smaller bladders and higher metabolisms and require more frequent trips outside. Your puppy's previous living conditions are another predictor. You may find that you need to help your puppy break old habits in order to establish more desirable ones.
