Getting a Dog When You Have a Cat: Managing the Introduction
Cats and dogs can live very happily together, but the introduction matters enormously. Done well, it sets the foundation for years of peaceful cohabitation.
Before the dog arrives
Prepare your cat's safe zones
Your cat needs guaranteed access to spaces the dog cannot enter. Set these up before the dog arrives. Use baby gates with a gap only the cat can fit through, around 13 to 15cm for most cats. Add elevated spaces such as cat trees and shelves that the dog cannot reach. Consider a room the cat can access via cat flap while the dog cannot. The cat must be able to reach their food, water, litter tray, bed, and your company without ever having to pass through a dog. This is not optional.
Begin scent introduction
If you know which dog you are getting, ask to bring home a blanket or item with the dog's scent before they arrive. Place this in your home and observe your cat's reaction. This gives your cat advance notice before the real thing.
The first few days: complete separation
The dog and cat should not see each other at all initially. The dog is confined to certain rooms; the cat has free access to the rest of the home. Swap bedding between the areas daily to allow scent familiarity to build. Allow a minimum of three to five days of full separation before any visual contact.
The first visual contact
When both animals seem settled and curious rather than distressed about each other's smell, introduce visual contact. The dog must be on a lead and in a calm sit or down position. Let the cat observe from wherever they choose to position themselves. Keep the session to five to ten minutes and end it before anyone becomes stressed. Reward the dog heavily for calm behaviour. A dog who lunges, barks, or fixates on the cat will create lasting fear in the cat. If the dog is overly aroused, do more obedience work before trying again. The cat must never be chased, even once, in the early stages.
Gradual progression
Over days and weeks, extend the sessions and gradually reduce the lead. Progress only when both animals are calm. Good signs include the cat remaining in the same room voluntarily, the dog no longer fixating on the cat, and the cat approaching the dog's area without distress. If the cat is consistently hiding after every session, or the dog cannot settle near the cat, slow things down.
Protecting the cat long-term
Even when cat and dog are comfortably cohabiting, keep cat food elevated so the dog cannot access it, keep litter trays behind a dog-proof barrier, and ensure the cat always has access to dog-free zones where they can fully relax. Most cat-dog relationships settle into a comfortable pattern within two to three months of careful introduction.

Frequently asked questions
How long does it take for a cat to accept a dog?
Most cat-dog pairs reach comfortable cohabitation within two to three months of a well-managed introduction. Some pairs become genuinely affectionate; others maintain a respectful distance. Both are good outcomes.
What if my cat hisses at the dog?
Hissing in the early stages is completely normal. It is your cat communicating discomfort. As long as the dog does not react by chasing or fixating, hissing will typically reduce over time as familiarity builds.
