Introducing Dogs to Dogs
A step-by-step approach to introducing a new dog to your existing dog.
The Gradual Introduction Process
A successful dog-to-dog introduction should be spread over days or weeks, not hours. Here is a proven approach:
Phase 1 — Scent Swapping (1–3 Days Before Meeting)
Exchange bedding, towels, or toys between the dogs so they become familiar with each other’s scent before any visual contact. Reward calm interest in the scent with treats.
Phase 2 — Parallel Walking (First Meeting)
Have two handlers walk the dogs on lead in a neutral location (not your home or yard). Walk parallel, with enough distance that both dogs are aware of each other but not fixated. Gradually close the gap over 15–20 minutes, rewarding calm behaviour. Let them sniff briefly if both are relaxed, then move on.
Phase 3 — Controlled Yard Time
If the parallel walk went well, allow them to interact in a fenced yard with leads trailing (not held). Keep sessions short (5–10 minutes). Remove all toys and food. Interrupt and redirect if play becomes too intense.
Phase 4 — Indoor Introduction
Bring the new dog inside on lead while the resident dog is already settled. Keep the first indoor sessions short. Use baby gates to give each dog their own space. Gradually increase shared time over the following days.
Phase 5 — Unsupervised Time
Only leave dogs unsupervised together once you have seen consistent relaxed behaviour over at least 2–4 weeks. Even then, separate them when you leave the house for the first month.

Dog Introduction Quiz
Where should two dogs meet for the first time?
During introductions, watch for the body language signals covered in our Reading Your Pet's Body Language course. Loose, wiggly bodies and play bows are good signs. Stiff posture, hard stares, raised hackles, and low growling mean you need to increase distance and slow down.
Never force dogs into close contact or hold them face-to-face. If either dog is showing stress signals, calmly increase the distance and try again another day. Some introductions take weeks. If there is any snapping, snarling, or fighting, separate the dogs immediately and seek professional help from a qualified behaviourist.
