INTEGRATING YOUR NEW DOG WITH AN EXISTING CAT
How you introduce your new dog to your cat or cats plays a significant role in
establishing their long-term relationship. We want your new dog and your cat to have
many happy years together!
We ask that you please follow the steps below to help them to get adjusted to each other:
1. Before your new dog arrives, set your new cat up in one room in your house; preferably a
bedroom, or any other room that you know where your cat feels comfortable. This room
should have a door, or should be a room where you can install a baby gate high enough for
the dog not to jump over. Avoid a room where you will not be interacting with your cat very
often (e.g., the laundry room or the basement) as this may only prolong the integration
process, causing more stress for your cat.
2. Place your cat’s food, water, litter box and toys in this room. Make sure the food/water and
litter are as far away from each other as possible (just like humans, cats do not want their
food close to their toilet!).
3. Bring your new dog into your home and let him/her explore everywhere except the room
where the cat is. When your dog starts to settle down (within an hour or so), give him/her a
good patting and leave your dog with someone (if possible) and go into the room with your
cat. Make sure to take treats with you! Sit with your cat and let her/him sniff your hands, then
praise your cat and give a few treats. Leave him/her and go back to your dog. How did your
cat react? If your cat is very fearful (hissing, growling, hiding after smelling your hands), you
may need to keep the cat in the room for a couple of days. If your cat shows indifference
(approaching the door, rubbing on your hands, lots of purring), this process may take only a
day or two.
It is very important that you do not force your cat to interact with your dog – both animals
need to adapt at their own pace. The more positive and happy the experience is, the quicker
they will feel comfortable with their future best friend.
4. If your cat has reacted fearfully, it would be best to wait until the next day to introduce the
cat to the dog. When you feel your cat is ready, follow steps 1-3 again.
5. When you are ready to introduce your new dog and cat nose-to-nose, leash your dog and
bring him/her to the door of the room where the cat is residing. Open the door, but do not let
the dog inside the room. Watch both animals’ behaviour towards each other. Any aggression
(lunging, snarling, barking) from your dog should be discouraged with a sharp “no!”, and then
bring your dog away from the door. The idea is to make your dog understand that the cat is
not prey, only play! Hissing and growling from your cat should be allowed, but not scratching;
use a “no!” and bring your dog away from the door. If they sniff noses, that’s a great sign!
6. Bring your dog away from the room, but leave the door open. Please leave your dog leashed
until you are confident he/she will not chase the cat. It is advisable to not leave your dog and
cat unsupervised until the cat is relatively comfortable (i.e., not hiding or excessively hissing
or growling). If you are unsure, you could put a baby gate in the doorway to the cat’s room
until you notice your cat approaching the dog on his/her own. If your dog is respectful of your
cat (showing playing behaviour or approaching the cat and sniffing, but not showing any signs
of aggression) praise both of them and give them treats. You are showing them that this is
the way you expect them to act in your house.
7. While your cat and dog are getting acquainted, we suggest putting a second set of food/water
and litter in their usual locations in addition to leaving the ones in the segregation room until
you see your new cat using them regularly. You want your cat to have a “dog free” zone that
they can retire to if they feel nervous, threatened or anxious – a place where they dog cannot
How will I know when I can let my cat out of the room?
Your cat will let you know when he/she is ready to come out of the room. He/she will be “out and
about” and interacting with you a lot. He/she might meow at the door, or paw at the door. Make
sure you leave the door open to the room to allow for a safe place to retreat from your dog if
startled or frightened. Keeping a baby gate across the door of this room will not only give your
cat a safe retreat, but will also keep the dog from eating their food or getting into their litter box,
as many dogs are prone to do.
What can happen if I don’t follow these steps?
Our experience with adoptions shows that cats adapt quicker to their new life if they are not
overwhelmed with what they perceive as the “commotion” of adding a new animal to their home.
Owners who do not allow for slow integration may see the cat fearful of the dog for a long time or
throughout their time together. As any cat owner knows, you don’t want to get on a cat’s “bad
side”. Some ways in which cats may show their stress and displeasure could be, but are not
limited to, not eating, going to the washroom outside their litter box, marking (particularly in the
case of male cats), hiding and/or showing aggression towards you (scratching, biting, not wanting
to be pet, etc.). Cats are complex animals, and typically have no qualms about showing their true
feelings. If your happy it unhappy, you will likely be very aware of it.
While most cats will integrate with a dog within a few days, some cats are more shy or have
never lived with a dog in the past, and may need more time to adjust. Kindness and patience is
the key! As long as there is no aggression present, we are hopeful that all furry family members
will be fast friends in no time.
