Getting a Cat and a Dog to Live Together: A Step-by-Step Introduction

October 22, 2026

A cat and a dog can live together very well, and some end up sleeping against each other. Success depends mainly on the first meeting and the weeks that follow. Take your time: a slow introduction avoids months of tension.

Before the meeting

Knowing both characters

Ask yourself a few honest questions. Does your dog tend to chase anything that moves? Have they lived with cats before? Is your cat rather curious or fearful? A dog with a strong chase drive or a very timid cat needs more time, and sometimes the help of a professional.

Preparing the flat

High refuges for the cat in every room: shelves, cat tree, top of furniture. They must be able to escape upwards at any moment.
A zone reserved for the cat, out of the dog's reach, with their litter tray, water and food. A child gate that the cat can get over or a door wedged slightly open is often enough.
A bed for each, in different places.

The steps of the introduction

Smells first. For a few days, keep the animals in separate rooms. Swap their blankets, and let each explore the other's room in their absence.
Seeing each other from a distance. Set up a gate or open a door slightly. The dog is on the lead, and you reward them when they stay calm. The cat approaches if they want to. A few minutes are enough.
Short, supervised meetings. Always with the dog on the lead, in a room where the cat has high spots. Stop before either one gets worked up.
Supervised freedom. When both stay calm several times in a row, take off the lead while staying present. Separate them when you go out, until you are sure they get along.

Allow a few days in easy cases, several weeks or even several months in others. Go back to the previous step at the slightest sign of tension.

Reading the signals

In the cat

ears flattened back, fur and tail puffed up, arched back;
hissing, spitting, raised paw;
a cat who hides and no longer comes out to eat.

In the dog

eyes fixed on the cat, stiff body, no response at all to your voice;
whining, barking, tight lead;
trying to chase as soon as the cat moves.

The good signs are often subtle: the cat who walks past the dog without speeding up, the dog who turns their head away, two animals calmly ignoring each other in the same room.

Rules that prevent drama

Never force contact. Do not hold the cat in your arms facing the dog: they could scratch you as they try to flee.
Punish neither one. Punishment links the other animal's presence with something unpleasant.
Reward calm, in both.
Never let the dog chase the cat, even "for play".
Give each one time alone with you, so that neither feels neglected.

Meals, litter and beds: each in their own place

Many conflicts come from resources.

The cat's food almost always attracts the dog. Put the cat's bowl up high or in their reserved zone: their kibble is not made for a dog.
The litter tray must stay out of the dog's reach, for the cat's peace and for hygiene.
Beds: the dog needs a bed of their own, in a quiet corner, away from the cat's routes. The Purré beds in our dog beds and cushions range have memory foam and a zipped cover washable at 30 °C, which is handy when the cat comes to leave their hair there too.

Some cats take over the dog's bed. If the dog accepts it, let it be. If they growl, offer the cat another soft spot, up high.

Kitten, puppy or adult animal?

A kitten and a puppy who grow up together often get used to each other more easily. Stay vigilant, though: a puppy plays hard and can hurt a kitten without meaning to. Conversely, an adult cat who has never been around a dog, or an adult dog who has never seen a cat, needs more patience. If you are adopting, ask the shelter or the previous home: they sometimes already know whether the animal has lived with a cat or a dog.

When to ask for help

If tensions do not ease after several weeks, if the dog shows a strong urge to hunt, or if the cat stops eating or using their litter tray, call on your vet or a veterinary behaviourist. A dog trainer can also help you work on the dog's calm.
