Introducing a Dog to a Cat: Step-by-Step Guide
A step-by-step guide to introducing a dog to a cat safely, with the cat's welfare as the priority throughout.
Stage 1: Preparation (before the dog arrives)
Set up cat-safe zones including rooms or elevated areas the dog cannot access. Ensure the cat can reach food, water, litter, and safe sleeping areas without encountering the dog. This infrastructure must be in place before any introduction begins. It is not a nice-to-have; it is essential.
Stage 2: Full separation (Days 1 to 5)
The dog stays in designated rooms while the cat has free access to the rest of the home. Swap bedding between the areas daily to build scent familiarity. Both animals should be eating normally and showing reducing tension about the other's smell before you progress to visual contact.
Stage 3: Visual contact through a barrier (Days 5 to 10)
Use a baby gate or slightly ajar door. The dog must be on a lead and in a calm sit or down position. The cat is free to approach, observe, or leave at any point. Keep sessions to five to ten minutes, ending before either animal is stressed. Reward the dog heavily for calm behaviour. Looking away from the cat is especially worth rewarding with praise or treats.
Stage 4: Supervised loose interaction (Week 2 onwards)
The dog on a long lead initially, allowing more movement but still under control. The cat should always be able to escape. End sessions as soon as either animal shows sustained stress. Progress to completely off-lead only when the dog reliably behaves calmly around the cat under various conditions.
Stage 5: Unsupervised cohabitation
Only when you are completely confident the dog will not chase the cat under any circumstances. Many owners maintain cat-only zones permanently as a sensible ongoing precaution.
The key rules throughout
- The cat must never be chased, even once in play
- The dog must be under control during all introduction sessions
- The cat always has the option to leave
- Go at the cat's pace as they are the more vulnerable party

Frequently asked questions
How long does it take for a cat to get used to a dog?
Typically two to three months for comfortable cohabitation, though timelines vary considerably depending on the individual temperaments of both animals and their prior experiences.
What should I do if the dog chases the cat?
Separate immediately and return to an earlier stage of the introduction process. The dog needs more obedience work and should not have any off-lead access near the cat until they reliably ignore or respond calmly to them. One chase can set the relationship back significantly.
