How to Stop a Puppy Bothering a Dog

Allow the dog to set the rules. Some dogs have higher tolerance levels than others, so it might just seem like the puppy is inflicting torture. Eventually, the older dog will put the puppy in its place by growling, pawing at him or simply shooing him away. This is actually the best option, as it will help both dogs find their place in the house.

Take the puppy on playdates. Let him spend time with other puppies that are as full of energy as he is. Chances are, he'll get some lessons on proper behavior from them as well, as puppies will have no problem biting, pushing or wrestling him to the ground. By the time he comes home, he'll hopefully be too tired to be too much of a pest to your other dog.

Stop the puppy if you think things are getting too rough. Some dogs are just too nice -- or maybe old or sick -- and won't do this on their own. Use a spray water gun or a can with some loose coins inside. When the puppy crosses the line, either spray it with water -- avoid the face, which can hurt -- or shake the can violently once. It will startle the other dog, too -- nothing you can do about that -- but hopefully it will scare the puppy enough to control his behavior.

Separate the dogs for at least a few hours every day. You could take the dog on walks by himself, or invest in a puppy gate. Separating the dogs shouldn't feel as a punishment for either one. For example, if you install a puppy gate to keep the puppy away, make sure the puppy can still see you so he doesn't feel like he's on a time out.
