Dogs and cats may be perceived as rivals, but in many homes, live together very happily. The key is taking things slowly and setting both animals up to feel safe from the very beginning. A rushed introduction can create fear or stress that’s hard to undo, while a gentle, well-managed approach gives your dog and cat the best chance of living together peacefully.
If you currently have only a cat, we wouldn’t usually recommend getting a dog purely to ‘keep them company’, as cats are naturally independent and often prefer being the only pet. That said, we understand that life circumstances can change, and sometimes dogs and cats do need to share a home. With careful planning and patience, this can be done successfully.
Every animal is an individual, and how they respond to a new companion depends on their temperament, past experiences and health.
If you already have a cat, think about how they react when they encounter dogs outdoors or through a window. A confident, curious cat may adapt more easily. Cats who are nervous, have had negative experiences with dogs, or already suffer from stress-related health issues may find a new dog very upsetting, which can seriously affect their wellbeing.
If you already have a dog, consider their behaviour around cats or other small animals when out walking. Ideally, they’ll show little interest and move on calmly. Dogs with a strong urge to chase, or who become highly excitable, may struggle to live safely with a cat.
If you’re rehoming through a rescue organisation, ask about your prospective pet’s history as some dogs may have lived happily with cats before, or been assessed as ‘cat-friendly’, which can make introductions smoother.
Before your new pet arrives, it’s important to create a home environment where both animals feel secure.
Cats need access to areas where dogs cannot reach them. A spare room works well for a new cat, while a familiar, dog-free space is essential for a resident cat. Move everything they need into this area, food, water, a bed and a litter tray, even if your cat usually goes outdoors.
Baby gates are particularly useful, allowing your dog and cat to see and smell each other safely while keeping clear boundaries in place. Some gates include small cat flaps, which can be helpful for older or arthritic cats, provided your dog can’t fit through.
Cats also feel safer when they can get up high. Cat trees, shelves or sturdy furniture they can climb will help them observe from a distance and escape if they feel overwhelmed.
For cats who are nervous or not used to dogs, a pheromone diffuser, plugged in a few days before introductions begin, may help reduce stress.
Kittens are particularly vulnerable due to their small size and playful nature, which can easily excite a dog. Because kittens can slip through baby gates, early introductions are often safest with the kitten housed in a large dog crate. This should contain a bed, litter tray, scratching post and hiding places, with part of the crate covered to help them feel secure.
Allow the kitten time to become comfortable using the crate before any introductions take place.
Smell plays a huge role in how dogs and cats understand the world. Before they meet face to face, it helps if they can become familiar with each other’s scent.
If possible, swap bedding between pets before the new arrival comes home. Once both animals are in the house, gently stroke each pet and then the other without washing your hands in between, helping to mix scents naturally. You can also use a soft cloth to collect scent from around a cat’s cheeks or a dog’s chest and place it in the other pet’s sleeping area.
This stage may feel slow, but it lays a vital foundation for calmer introductions later on.
Once your new pet arrives, keep dog and cat separate at first. A new cat should stay in their safe room for a few days while they settle in and get used to household sounds and smells. This also allows time for continued scent swapping.
If you’re bringing a cat into a dog’s home, let the cat explore shared spaces only when the dog is out of the house initially, so they can build confidence without pressure.
When you’re ready for the first visual introduction, choose a calm moment, ideally after your dog has had some exercise. Make sure your cat always has a clear route back to their safe space.
Your dog should be on a lead and kept behind a baby gate. Allow your cat to approach in their own time; many cats prefer to watch quietly from a distance at first. Never force them closer, frightened cats can scratch or bite if they panic.
Reward your dog for calm behaviour with praise, and small treats if needed. Brief glances are fine, but if your dog fixates or becomes overexcited, gently distract them and increase the distance. Keep these early meetings short and positive.
If either pet seems frightened, take a step back and give them more time apart before trying again.
As both animals become more relaxed, you can allow longer interactions. Keeping your dog on a lightweight indoor lead can help you step in quickly if excitement builds. This is particularly important for dogs who are young, energetic, or breeds that enjoy chasing.
Eventually, when you’re confident your dog won’t chase and your cat is moving around comfortably, you can remove barriers. High resting places for your cat remain essential, even once things are going well.
Never leave a dog and cat together unsupervised until you’re completely confident they are safe.
Even the best of friends need their own space. Cats should always be able to eat and use the litter tray without being watched or disturbed by a dog. Keep cat food and litter trays well out of your dog’s reach, as interference can cause significant stress and lead to toileting problems.
Remember that every introduction is different. Some dogs and cats settle quickly; others may take weeks or months. Progress at the pace your pets are comfortable with and avoid rushing.
If you’re worried about safety or stress at any stage, speak to your vet, who may refer you to a qualified veterinary behaviourist for extra support.
With patience, preparation and plenty of calm reassurance, many dogs and cats learn not just to tolerate one another, but to share a home contentedly. A slow, thoughtful introduction is one of the kindest things you can do and gives your pets the best chance of building a peaceful life together.
