Two dogs do not need to greet nose to nose in the front doorway. The resident dog may protect familiar space, and the newcomer may be overwhelmed. A planned introduction gives both dogs a chance to notice each other without being trapped in a close encounter.
Meet with one handler per dog in a neutral place, begin at a comfortable distance, and walk in parallel if both are relaxed. At home, separate food, beds, and high-value items and supervise brief interactions.
Prepare separate resources before the meeting
Set up a resting place, water, and a way to separate the dogs with doors or gates. Put away food bowls, favorite toys, chews, and other items that could cause competition in shared areas. Check that both dogs are healthy enough for contact and ask the rescue or your veterinarian about unknown vaccination or parasite history.
Choose a neutral, quiet place for the first meeting, with one calm handler per dog. Each handler should have a secure leash and enough room to move away. If either dog has a history of serious aggression, ask a qualified behavior professional to plan the introduction rather than improvising.
Begin at a distance and watch both dogs
The RSPCA step-by-step guidance recommends gradual contact, often starting with a parallel walk. Keep enough distance that both dogs can sniff, move, and respond to their handlers. Reward calm behavior. Move closer only if both remain comfortable; do not drag one dog toward the other.
Watch for stiff posture, hard staring, repeated lunging, growling, or one dog trying to escape. Increase distance and end the session if tension rises. A brief sniff followed by moving on is often better than a prolonged face-to-face greeting.
