Introducing a new animal into a household with established pets can spark anxiety, territorial aggression, or fear-based behaviors. As a multi-species behaviorist, I’ve facilitated hundreds of introductions between dogs, cats, rabbits, and more. Below is a phased, species-agnostic protocol ensuring safe, stress-minimized integration.
Phase 1: Scent Exchange (Day 1–3)
Swap bedding: Rub new pet’s blanket on resident and vice versa.
Door feedings: Feed each pet on either side of a closed door to build positive scent associations.
Phase 2: Visual Introduction (Day 4–6)
Barrier interactions: Use baby gates or carriers; supervise side-by-side feeding and play.
Short sessions: Start with 5-minute meetings, gradually increasing to 15 minutes.
Phase 3: Controlled Face-to-Face (Day 7–10)
Leashed dog/secured rabbit: Maintain safety with harnesses or carriers.
Neutral territory: Conduct initial meetings in a room neither pet claims.
Phase 4: Full Access (Day 11+)
Monitor body language: Watch for stiff posture, growling, piloerection—intervene calmly.
Positive reinforcement: Reward calm, exploratory interactions.
Troubleshooting Common Issues
Dominance displays: Redirect with toys and ignore low-level threats.
Fear responses: Provide higher perches for cats and hideaways for prey species.
Conclusion:
Structured, gradual introductions leveraging scent, sight, and direct contact ensure harmonious multi-pet households. Patience, consistency, and positive reinforcement are your allies.
