The Second Dog – Five Things to Know As You Introduce Your Current Dog to Her New BFF

Becoming a multi-dog household can be a fun and exciting adventure, but it’s important to make sure things are done the right way. Having two or more dogs together can form a “pack” that is happy together, but it takes proper introductions and careful acclimation—especially for the dog or dogs who have already been living in the household.

Here’s a look into five things to know as you introduce your dog to her new best friend:

1. Introduce the pair in a neutral location.

Because of the territorial nature of some dogs, it’s best to introduce the new dog to the current canine away from the home turf. Since the original companion has called your place home for longer, the house and yard could be viewed as noncommunal property. Therefore, introductions should be made in a park, out in the neighborhood, or in another location where neither dog feels the need to be protective.

2. Don’t force any interactions, and feeding separately is best.

Don’t force the two dogs to physically interact with each other as they become acquainted. Dogs will typically sniff each other and politely greet one another when they first come in contact. Wagging tails, relaxed and (lightly) playful behavior all indicate that the meeting is going positively. Watch closely for signs of apprehension and be sure both dogs are on a leash. For two dogs to live together in peace, it’s important to assess the initial interaction and watch out for signs of potential food aggression or any possessiveness of toys, furniture, or you!

3. Don’t leave the two unattended until you have full and complete confidence.

One of the worst things you can do when introducing two dogs who are not yet familiar with each other is to leave them unsupervised. Anything can happen away from vigilant eyes, and the worst-case scenario is an altercation that could damage the developing relationship between the two dogs—temporarily or permanently. A negative reaction can be especially damaging for a puppy, causing issues as it develops mentally and temperamentally.

4. Keep a close and watchful eye on body language.

Make sure to watch for any potentially negative body language between the two dogs, especially in the beginning stages of contact. Signs of unfavorable body language include intense staring, the body leaning forward, a tail raised stiffly, barking, showing teeth, and, of course, growling, snapping, and biting. If one or both dogs display any of these behaviors initially, it’s best to keep them apart and consult with an experienced behaviorist if necessary.

5. Make it an all-around positive experience.

Be sure to keep things happy and upbeat as your new dog gets to know your household’s first four-legged resident. If the new dog is a puppy, do not scold the older dog for growling. Just make sure to intervene if any aggressiveness goes beyond a mere warning. Puppies are still learning their communication skills and are still developing mentally; a growl from an adult dog lets them know when it is time to back off. Most importantly, reward both dogs when they are behaving appropriately. And remember to enjoy all of the adventures that come with living in a multi-dog household!
