How to Stop an Older Dog from Being Aggressive to a Puppy

Dogs are pack animals, and despite a human's best intentions, they will develop a ranking from the most-respected lead dog to the least-respected subordinate pooch. However, it is unacceptable to put a new puppy into a situation where he may be bitten by an older dog that is none too thrilled with the idea of having a playful puppy around. By introducing the dogs slowly, the older dog may more easily accept a new family member.

      Recruit a friend to help you introduce the two dogs in a neutral place. This can be in a parking lot or other open area. Each person will hold one dog on a leash and approach each other. Since the older dog is not on his home turf, he may not feel threatened. If either dog seems uncomfortable or aggressive, do not move closer. Instead, walk about casually, allowing the dogs to view each other from a distance until they are at ease.

      Enforce the natural hierarchy. While lavishing attention on puppy is expected, your older dog may find your actions confusing, and he may feel his position in the home is threatened. You can alleviate his anxiety by feeding him first, petting him first and allowing him to have a special toy.

      Install a baby gate in a doorway between two rooms and put your puppy in one room and your older dog in the other. You older dog will feel more comfortable if he does not have the puppy thrust upon him out of the blue.

      Provide new items for your puppy; don't expect your older dog to share his bed, his food bowl or his toys. Dogs have no comprehension of sharing and they view these items as sole possessions. You will reduce tension and animosity by using each dog's items for only that dog.

      Keep a new puppy separated from an older dog if the puppy is rambunctious and the older dog is arthritic or suffers from pain. When a dog feels pain upon moving, he will frequently snap or bite at another animal that comes too close.
