How To Introduce A New Puppy To A Cat
Plus tips for when your cat's reallyyy not feeling it đł

Cats and puppies â are they mortal enemies or best friends?
When youâre bringing your new puppy home to meet your cat, youâre obviously hoping theyâll end up BFFs.
And they probably will, but itâs best to be prepared with a plan so you can help them start off on the right foot.
So The Dodo spoke with Dr. Stefanie Schwartz, a veterinary behaviorist at Pet Behavior Medicine in California, who offered some advice about the best way to introduce your puppy to your cat.
Introducing a puppy to a cat
When it comes to introducing your new puppy to your cat, the outcome is going to depend on a ton of factors.
Things like the size and the age of your puppy are going to affect just how threatened your cat will feel by his new roomie.
âIf weâre talking about a puppy thatâs around the same size or smaller than the cat, it may be less threatening to the cat,â Dr. Schwartz told The Dodo. âBut it also means itâs an easier victim if the cat is not accepting.â
On the other hand, the bigger the puppy, the bigger the visual threat to your cat.
âIf a puppy is larger than a cat ⌠then thatâs an immediate threat to most cats, unless theyâre a cat that had a dog before the new puppy,â Dr. Schwartz said.
If your cat has lived with a dog before, you might have an easier go of it, since your cat will have some idea of what to expect, and your puppy wonât feel as unknown or unfamiliar.
âIf itâs a new puppy for a cat thatâs never been with a dog, then youâre basically starting at a deficit, regardless of the size of the puppy, because they have no reference and no experience, so itâs not usually well-accepted,â Dr. Schwartz explained. âAlthough there are always exceptions.â
You want the two of them to get along more than anything, but thereâs really no telltale sign of how the introduction will go.
âItâs difficult predicting that magic in any relationship, regardless of the species,â Dr. Schwartz said. âSo much of it is visual, but sometimes ⌠cats and dogs can fall in love with each other and be best friends, or they can hate each other instantly just like people do.â
But even if itâs not love at first sight, all hope isnât lost!
âEven a cat whoâs never seen a dog before can sometimes take it in stride and work it through and think about it and then they can become really good friends,â Dr. Schwartz said.
While you canât entirely control how your puppy and your cat will feel about each other, there are some things you can do to make sure their interactions go the best they can.
â[If youâre] letting things go naturally and just putting up levels of security and letting things proceed by baby steps, they will at least learn to coexist, if not become really good friends,â Dr. Schwartz said.
Tip #1: Set up baby gates
âThe first thing I would do is put up lots of baby gates to section off [parts of the house] so that the cat can get away,â Dr. Schwartz said.
The last thing you want is for your cat to feel backed into a corner, because thatâs when aggressive behavior can come out (since he wonât feel like he has any other choice).
So try this gate from Chewy for $34.99
âFor the average age cat and the average puppy, the baby gates are helpful because it gives the cat the opportunity to avoid the dog, and [prevents] the dog [from pursuing him],â Dr. Schwartz explained. (Thatâs because most cats can jump over the gates, while a puppy will be stuck behind them.)
Try putting the gate in places like:
- The hallway
- The kitchen
- The entrance to the catâs favorite room
Tip #2: Keep the puppy on a leash
Dr. Schwartz also recommends putting your puppy in a harness or a collar and keeping her on a leash while introducing her to your cat.
âSometimes just restraining the puppy while the cat has a chance to visually inspect them and smell them ⌠then that can help too,â she said.
Try this collar from Chewy for $6.49+
Or this harness from Amazon for $12.99+
And this leash from Chewy for $8.79
âUnless the cat is clearly not aggressive, most pet owners are ⌠concerned about the cat scratching the puppyâs eyes if their face gets too close,â Dr. Schwartz explained. âThat does happen, no question, but most of the time if the puppyâs restrained and the cat has a chance to leave, they will simply leave rather than attack.â
Tip #3: Nap time might be the best time
If you donât want your cat to only see your new puppy as a threat, consider letting him try to approach the pup while sheâs sleeping.
âPuppy naps are sometimes a nice opportunity to let the cat get in a little bit closer,â Dr. Schwartz said. âWhen the puppy is sleeping, thatâs sometimes a nice time to let the cat out and check out the puppy while [sheâs] sleeping, since puppies tend to sleep really hard.â
Tip #4: Give your puppy another energy outlet
Itâs super important to make sure youâre giving your puppy plenty of exercise and the chance to play with other puppies (provided sheâs had all the right shots, of course).
âIf [your puppy is] kept inside and not allowed to develop social relationships with another playmate, then itâs all going to be focused on the cat,â Dr. Schwartz explained.
This might not seem like a bad thing, but you have to remember that dogs and cats donât play the same way, so your cat might feel threatened by your puppy when all sheâs trying to do is play.
âAlthough there are some dogs and cats that absolutely play together, most of the time it ⌠wonât go well,â Dr. Schwartz said.
Tip #5: Obedience training is key
Obviously, youâre going to want to train your puppy anyway, but basic commands are actually super helpful when introducing her to your cat.
âMost puppies can learn to âsitâ [or âcomeâ] at a very young age,â Dr. Schwartz said.
This can be especially useful if youâre introducing your pets and your cat is NOT having it.
âIf the puppy knows âcomeâ and the puppy is about to pounce on the cat or vice versa, then the owner can [give the puppy a command],â Dr. Schwartz explained.
It can even help if their relationship is off to a rocky start, since it will allow your cat to build trust with your puppy.
âCats donât necessarily trust right away,â Dr. Schwartz said. âOnce [the cat] sees they arenât in any danger and that [the puppy] is not a threat [because she backed off when you called her], then that opens the door for them to have a good relationship.â
Tip #6: Keep their food away from each other
You definitely donât want your cat or your puppy to develop food aggression â especially not if itâs directed toward each other.
So your best bet is to make sure they have their own designated eating areas.
âFeed the cat from an elevated surface or in a room thatâs closed in,â Dr. Schwartz said.
Try these elevated bowls from Chewy for $31.95
âFor the dog, pick up any leftover food in the bowl, because you donât want either of them to start getting negative association with the other over food,â Dr. Schwartz explained.
Tip #7: Keep your cat separated when your puppy first comes home
Your cat may have been there first, but your place is now your puppyâs home, too.
So itâs only fair to give her a chance to get to know her new digs without the risk of your cat interfering or making her feel uncomfortable.
âInitially, when you bring the dog in, itâs sometimes nice to have the cat closed in and let the puppy come in, check out the place and kind of take their introduction in baby steps,â Dr. Schwartz said.
Things to watch out for when introducing your puppy and cat
Obviously, signs of aggressive behavior are going to be your main concern when introducing your puppy and your cat.
(For example, if your pup is a breed thatâs more active or prey-focused, like a husky, youâll want to go really slowly with introductions.)
The biggest red flag would be predatory aggression.
âIf the dog is being very quiet and looks like itâs stalking the cat and like itâs absolutely not playing ⌠thatâs the kind of thing that youâre very unlikely to get over because thatâs very hardwired,â Dr. Schwartz explained. (Thatâs a case where youâll definitely want to consult a professional trainer.)
And even if your pets donât get along right away, donât give up hope!
â[If your pets donât like each other,] definitely leave the baby gates in place and make sure that the dog gets basic obedience training,â Dr. Schwartz said.
Making sure those precautions are in place could still help your cat and dog eventually build trust with each other.
After all, according to Dr. Schwartz, it can take six to 12 months to get used to any new relationship.
So sometimes you just need to give it time.
