The secret to blending pet families is going slowly. Introduce pets on neutral ground or through a barrier, give every pet their own space and supplies, and supervise them together until you're sure they get along. With 95 million U.S. households owning at least one pet, plenty of couples bring a dog, a cat, or both into a new home together.¹ A little planning can help your pets become family, too.
Blending Pet Families at a Glance
Every pairing needs a slightly different approach. Here's a quick guide based on AKC and International Cat Care advice:²³⁴
Pairing | Where to start | Key tip | Typical timeline |
|---|---|---|---|
Dog and dog | Meet on leash in a neutral space | Pick up toys and food before they meet at home | Varies by dog |
Cat and cat | Separate rooms and scent swapping | Each cat gets their own resources, plus one extra | Several days to a week or two |
Dog and cat | Separate spaces for the first few days | Give the cat a permanent dog-free space | A few weeks or months |
What Should You Do Before You Move In Together?
Start with a conversation between the two of you. Talk about each pet's personality, routines, and quirks. Does one dog guard toys? Does one cat hide from visitors? Agree on house rules, like whether pets are allowed on the bed, who handles feeding and walks, and how you'll split pet costs.
Then go over the practical details:
Check pet limits. Make sure your lease or HOA allows all of your pets, including any breed, size, or number limits.
Gather vet records. Share vaccination histories and health records, and decide whether you'll keep separate vets or use one.
Prepare the space. Plan separate rooms or gated areas so pets can adjust without being forced together.
How Do You Introduce Two Dogs?
The American Kennel Club suggests starting dog introductions in a neutral space with both dogs on leash, at a distance where both are calm, before bringing them home together.² Before the first meeting at home, pick up food, treats, and toys that could cause tension.
Keep leashes on during the first meeting inside so you can separate the dogs if needed. When you can't supervise, keep the dogs in separate crates or rooms, and be extra careful if your dogs are very different sizes. Mealtimes, treats, and chews can spark guarding, so feed the dogs apart. Learn more about resource guarding in dogs.
How Do You Introduce Two Cats?
Cats need even more patience. International Cat Care suggests a gradual, step-by-step approach:³
Swap scents. Keep the cats in separate areas and swap bedding so they get used to each other's smell.
Swap spaces. Let each cat explore the other's area while the other cat is elsewhere.
Let them see each other. Use a stair gate or a mesh or glass barrier.
Allow supervised time together. Keep early sessions short and calm.
Give short periods of unsupervised time. Only move on when both cats seem relaxed.
Make sure each cat has their own food and water bowls, beds, litter trays, and scratching areas, plus one extra, spread around the house. If a cat hisses, growls, or tenses up, calmly distract them and slow down. Never punish a cat during introductions.
How Do You Introduce a Dog and a Cat?
The AKC suggests keeping a new dog and cat apart for at least the first few days so they can get used to each other's sounds and smells.⁴ Give each pet a safe room, and take turns letting them roam the rest of the house. Feeding them on opposite sides of a closed door can help them link each other's scent with something good.
For the first face-to-face meetings, use a dog gate or screen door, keep your dog on a leash, and let your cat move freely so they can leave. Try a few short sessions a day. Give your cat a permanent dog-free space with a litter box, food, water, a bed, and a scratching post, and feed your cat somewhere the dog can't reach.
What Are the Signs Your Pets Aren't Getting Along?
Watch your pets' body language closely, especially in the first weeks. Warning signs include:³
A stiff body or a hard stare
Raised hackles or a lifted lip
Growling, snarling, or hissing
Guarding food, toys, beds, or people
A cat that hides constantly or stops using the litter box
If you notice these signs, slow down and go back to the last step that went well. Our guide to cat body language can help you read your cat's mood. If tension keeps building, talk to your vet. They can check for medical issues and refer you to a qualified trainer or veterinary behaviorist.
Don't Forget the Pet Paperwork
Combining households is a good time to update your pets' records:
Microchips. The AKC suggests including phone numbers for everyone in your household who is responsible for your pet, and keeping your contact information up to date with the registry.⁵
ID tags. Update tags with your new address and both partners' phone numbers.
Vet records. Add both partners as authorized contacts at your vet.
Pet insurance. Review each pet's coverage, and ask whether your insurer offers multi-pet savings once your pets share a home.
Frequently Asked Questions
How long does it take for pets to adjust to each other?
It depends on the pets. Some cats settle in within several days to a week or two,³ while dogs and cats may need a few weeks or months before they can safely be left alone together.⁴ Go at your pets' pace, not a calendar's. Rushing introductions can set things back, so take small steps and celebrate calm moments.
Should we introduce our pets before we move in together?
If you can, yes. Short, calm meetings before moving day, like on-leash walks for dogs, can make the transition easier. Cats usually do better meeting in the new home, where you can set up separate rooms and follow a gradual introduction. Either way, plan for your pets to need time once everyone lives under one roof.
What if our pets never get along?
Some pets need more time and help than others. If tension keeps building despite slow introductions, talk to your vet, who can rule out pain or illness and refer you to a qualified behavior professional. Many pets learn to share a home peacefully with separate spaces and routines, even if they never become best friends.
Should our pets be part of our wedding?
They can be, but plan carefully. Crowds, noise, and new places can stress pets, especially while they're still adjusting to each other. Consider a pet sitter or a trusted friend to handle your pet on the day, or include your pets in engagement photos instead. Always put your pets' comfort and safety first.
