Do Cats and Dogs Get Along? How to Build Peace at Home
By Dr. Zubair Khalid, DVM, MS, PhD ·

Do cats and dogs get along? Often they can, and many live together comfortably once they learn each other's rules. The answer depends less on species and more on the individual animals, their ages, and how carefully you manage the first few weeks. This article is educational and is not a substitute for veterinary diagnosis or treatment.
Quick Answer
- Most cohabiting dogs and cats in surveyed households were reported as comfortable and friendly with each other, and a younger age at first introduction strongly predicted greater amicability [1].
- The dog's behavior around cats matters most, but cats can also start trouble, so both animals need management [2].
- A cat who is older, easily stressed, or dealing with health problems may not adapt well to a new dog, and it may be kinder to wait [2].
- Never adopt a dog with a known history of aggression toward cats and expect training to fix it [2].
- Give the cat escape routes, vertical space, and a dog-free room from day one, because cats use avoidance to reduce conflict [3].
Why Do Dogs and Cats Get Along, or Not?
Dogs and cats are different species with different body language, and that mismatch explains most of the friction you will see. A dog who stares, looms, or charges is being rude by cat standards. A cat who hisses, swats, or bolts can trigger a dog's chase instinct. Neither animal is being malicious. They are reading each other through filters that do not line up.
Age at First Meeting Matters
When do cats and dogs get along best? The evidence points to early introductions. In a survey of 777 Japanese households with both species, a younger age of introduction strongly predicted greater amicability between the dog and cat [1]. That pattern matches earlier surveys of pet owners in Western countries, where age at cohabitation onset and cat-related factors were the main determinants of how well the pair got along [1]. A puppy and a kitten raised together often settle into a truce quickly. Two older animals meeting for the first time need more time and more supervision.
Personality Beats Species
How often do cats and dogs get along is really a question about the two individuals in front of you. A laid-back adult cat and a dog who has lived with cats before have good odds. A fearful cat and a dog with a strong chase drive have poor odds, at least at first. The Japanese survey found that both dog factors (comfort around cats, offering toys) and cat factors shaped the relationship [1]. That means you are not managing one animal. You are managing a pair.
Cats Are Not Small Dogs
Cats handle social tension differently. In a study of 27 cats living in a group setting, cat-to-cat interactions were infrequent and mostly friendly, and the cats leaned on avoidance as their main conflict-reduction strategy [3]. They also preferred elevated structures, especially when the space was busy, and retreated to cat-only areas when they could [3]. Your cat will do the same thing at home if you let them. Height and hiding spots are not luxuries. They are how cats cope.
Medical Causes to Rule Out First
Behavior that looks like a personality clash can have a physical cause. Pain, dental disease, arthritis, thyroid problems, and vision or hearing loss can all make a pet more irritable or more reactive. A cat with an untreated painful condition may swat at a dog who simply walks past. A dog in pain may growl at a cat who brushes against a sore hip.
Feline aggression has both genetic and environmental contributors, and the research on its causes is still incomplete [4]. That is one reason a veterinary exam belongs early in the process, not at the end. If your cat or dog has a sudden change in how they treat the other pet, book a checkup before you assume it is behavioral.
Stress itself is a medical issue. A cat who stops eating, hides all day, or starts urinating outside the box is not being stubborn. Those are signs that need a veterinarian.
When Does It Become a Problem?
Some tension is normal in any multi-pet home. A problem is when the tension changes daily life for either animal.
Watch for these signs in your cat:
- Hiding constantly or refusing to come out for food
- Avoiding the litter box, or eliminating outside it
- Overgrooming, especially bald patches on the belly or flanks
- Hissing, growling, or swatting every time the dog comes near
- Eating less or losing weight
Watch for these signs in your dog:
- Staring at the cat for long periods and stiffening
- Blocking the cat's path or cornering them
- Chasing that does not stop when you call
- Guarding food, toys, or you from the cat
- Whining, pacing, or drooling when the cat is nearby
If the two animals are simply avoiding each other, that is often a workable outcome. Peace does not require cuddling. It requires that both pets can eat, sleep, and move through the home without fear.
How Can Cats and Dogs Get Along? Step by Step
Step 1: Separate Spaces Before the First Meeting
Set up a base camp for the newcomer before they come home. The cat should keep access to their own room, food, water, litter box, and favorite perches. The dog gets a separate area with a bed, water, and a gate or closed door between them.
This is not a temporary inconvenience. It is the foundation. Cats rely on vertical space and cat-only zones to manage stress [3], so plan shelves, cat trees, and a baby gate the cat can jump but the dog cannot.
Step 2: Swap Scents
Before they see each other, let them smell each other. Rub a cloth on the dog's cheek and leave it near the cat's resting spot. Do the same in reverse. Feed both animals on opposite sides of a closed door so they pair the other's smell with something good.
Step 3: Controlled Visual Introductions
Use a gate or a cracked door so they can see each other without contact. Keep sessions short, a few minutes at a time. Reward calm behavior in both animals. If the cat walks away, let them. If the dog fixates, end the session and try again later at a greater distance.
For a detailed sequence, see How to Introduce a New Dog to Your Cat: Step-by-Step Guide.
Step 4: Supervised Time Together
When both animals stay relaxed at the gate, try short supervised sessions in the same room. Keep the dog on a leash at first. Let the cat choose the distance. End on a calm note, not on a chase.
Step 5: Build the Dog's Obedience First
A reliable "come," "leave it," and "settle" gives you control when the cat walks by. Practice these away from the cat, then add distractions. A dog who responds to you around the cat is a dog you can trust more.
Step 6: Enrichment for Both Animals
Boredom fuels conflict. Give the dog puzzle feeders, chew toys, and daily exercise. Give the cat hunting-style play with a wand toy, food puzzles, and climbing routes. A tired, mentally satisfied dog is less likely to fixate on the cat. A cat with outlets for stalking and pouncing is less likely to ambush the dog.
Step 7: Manage Resources
Feed the animals in separate rooms or at separate times. Provide multiple water bowls, litter boxes, and resting spots so nothing has to be shared. Resource guarding is one of the most common triggers for conflict between species.
If the dog is the one doing the chasing or guarding, see Dog Aggression Towards Cats: How to Manage Multi-Pet Households. If the cat is the aggressor, Cat Aggression Towards Other Cats: How to Manage Multi-Cat Households covers the same principles for feline-to-feline tension, and much of it applies to cats and dogs too.
What Not to Do
Do not punish either animal. Yelling, spraying, or swatting teaches fear, not manners. It also risks teaching the cat that the dog's presence predicts something scary, which makes the relationship worse.
Do not force interaction. Holding a cat up to a dog, or crating a dog next to a cat, does not build friendship. It builds stress.
Do not assume a shelter test tells the whole story. A dog tested with cats at a shelter may behave differently in your home, though shelter staff can usually give a good sense of how the dog handles feline company [2]. Use that information as a starting point, not a guarantee.
Do not believe the myth that cats and dogs are natural enemies. Most owners in the Japanese survey reported comfortable, friendly relationships between their dogs and cats [1]. The species can live together well.
Do not skip the cat's needs to focus on the dog. The resident cat often feels put out by any new family member, and the integration goes more smoothly when the dog is taught to respect the cat's space [2].
Do not ignore early warning signs. A single hard stare can become a chase. A single swat can become a bite. Address patterns early, when they are still small.
When to Bring In a Veterinarian or Behavior Professional
Call your veterinarian if either pet shows sudden behavior changes, stops eating, starts hiding, or develops new elimination problems. These can be medical, and they need a physical exam.
Ask for a referral to a board-certified veterinary behaviorist or a certified applied animal behaviorist if:
- The dog has injured or nearly injured the cat
- The cat is too fearful to eat, use the litter box, or move through the house
- You have followed a gradual introduction plan for several weeks with no improvement
- Either animal shows aggression toward people as well
- You feel unsafe managing the two animals together
A veterinarian can also discuss medication for severe anxiety or aggression. The dose depends on your pet's weight, health, and other medications, so your veterinarian calculates it for your individual animal. Never give a pet medication prescribed for another animal or for a person.
Limitations and When to Contact a Veterinarian
No article can assess the two animals in your home. Individual cases need a veterinarian who can examine your pets and see the behavior in context.
Contact a veterinarian the same day if:
- Your cat has not eaten in 24 hours
- Your dog or cat is limping, yelping, or showing pain after an interaction
- Either pet is hiding and will not come out for food
- You see a sudden change in personality or energy
Go to an emergency clinic now if:
- There is a bite wound that is bleeding, deep, or punctured
- Either pet is having trouble breathing, is pale, or is collapsing
- Your cat is straining to urinate or cannot urinate
- You suspect a broken bone or internal injury
Call your regular veterinarian for a routine visit if:
- The tension is mild but ongoing
- You want help planning an introduction
- You need a behavior referral
- Either pet needs a checkup before you add another animal to the home
If you ever suspect your pet swallowed a medication, a houseplant, or a human food that could be toxic, call the Pet Poison Helpline or the ASPCA Animal Poison Control Center right away. Keep those numbers saved in your phone before you need them.
Frequently Asked Questions
Can a dog and cat become friends?
Yes, many do. In a survey of households with both species, most owners described their dog and cat as comfortable with each other and friendly [1]. Friendship usually looks like tolerance first, then relaxed coexistence, and sometimes grooming or sleeping near each other.
Is it better to get a puppy or a kitten if I already have the other species?
A young animal is generally easier to integrate because early introductions predict better relationships [1]. That said, a calm adult dog who has lived with cats can be a better match than a high-energy puppy. Match energy and temperament, not just age.
How long does it take for a dog and cat to get along?
There is no fixed timeline, and the research does not establish one. Some pairs settle in days, others take months of gradual work. Progress should be steady, even if it is slow. If nothing improves after several weeks of structured introductions, get professional help.
Will my cat ever accept a dog?
Many cats do accept a dog, especially if the dog learns to give the cat space [2]. Cats reduce conflict mainly by avoiding each other [3], so a cat who can leave the room, climb, or hide is often a cat who copes fine. A cat who cannot escape will stay stressed.
Should I let them "work it out" on their own?
No. Unsupervised conflict can escalate to injury, and it teaches both animals to fear each other. Supervise interactions, keep the dog leashed during early meetings, and separate them when you cannot watch. If you are seeing real aggression, see Dog Cat Behavior Problems and talk to your veterinarian about a behavior plan.
