Play-fighting is as natural a pastime for puppies as it is for preteens. It's a way for puppies to learn how to interact with other dogs, and it's rarely anything but innocuous behavior. Play-fighting is generally a healthy thing for pups because it's a natural part of their development. Overly aggressive puppies do exist, however, so look for certain signs when your pups are rough-housing. Determining if puppies need to be separated is the key.
Instructions
Observe your puppies while they are play-fighting. Look for signs that may indicate overly aggressive behavior. Dogs that are fighting will make direct eye contact. Their bodies will be still and rigid. In a true fight, you won't hear much sound because the dogs are silent and concentrating. If your dogs are not exhibiting such behavior, they are play-fighting. There is no need to stop your dogs from play-fighting if these signs of aggression are absent.
Listen for loud squeals or shrieks that do not sound playful in tone. If the fighting seems to be causing pain to one of the pups, separate them until things calm down. Keep them apart for at least 15 minutes and then reintroduce them in a calm environment. Don't scream or exhibit any violence toward the dogs. Avoid slapping or any other physical disciplining of the puppy.
Take time to cuddle with and reassure each puppy that it is loved and appreciated. Let it know that it is safe and sound by hugging and stroking it. Do this to each one, but give each of the puppies its own time to be alone with you. Like children, puppies respond to affection and care. They will be far less likely to exhibit violent outbursts if they feel cared for and safe.
Offer your puppies the chance to engage in physical activity. Running and jumping will allow them to tire themselves out in a healthy way, and a tired-pup is less likely to have pent-up negative energy. A focus on positive ways to expend energy will benefit the puppies and decrease the chance they will feel angry or uncared for,
Consider positive dietary changes if one of your puppies is too aggressive. Diet plays a large role in the way people act. Why would it be any different in animals? Consider feeding your dog quality organic food with fewer impurities. Look into doggie supplements, too.
