Cat to Dog Introductions That Actually Work

Bringing Home a Dog When You Have a Cat: Set Everyone Up for Success!

Adding a new dog to your family is exciting—but for your resident cat, it can feel like a major disruption. Cats are sensitive creatures who thrive on predictability, and introducing a new species into their space requires patience, planning, and a good understanding of both feline and canine behavior.

This guide is designed specifically for cat households welcoming a new dog. We’ll walk you through everything you need to know—from prepping your home and managing initial separation to reading body language and facilitating slow, safe introductions.

At Cincinnati Animal CARE, we know successful cat-dog relationships are built on trust and time. With realistic expectations and thoughtful guidance, you can help your cat and new dog start off on the right paw. Let’s make this introduction a smooth one for everyone—especially your feline friend.

Swap Scents

Switch any bedding or fabric between your new cat and your resident animal. This should be done with any frequently used bedding from each of the resident animals.

Swapping Living Quarters

Once your new cat has acclimated to their confined area, let them have free time in the the home while confining your other animals to the new cat’s room. This swapping process allows the new cat to become familiar with animals to the newings without being intimidated by the other animals in the home. It also provides a secondary way for the animals to get to know each other’s scents without meeting face-to-face.

Positive Reinforcement

Once the previous steps have been completed with no negative reactions, you may begin the face-to-face introductions. This can be done by providing high-value treats in front of the closed door to both the dog(s) and new cat. After a couple days, the closed door can be swapped with a baby gate or something similar.

Face-To-Face… For Real!

You’re almost there! Assuming all of the other steps have been completed successfully, you may begin supervised face-to-face introductions without a barrier. It is recommended that you still incorporate high-value treats and not leave the cat with the dog(s) unsupervised until they have established a bond or accepted the presence each other. It is important that the cat always have hiding places and vertical places higher off the ground to retreat if the need or choose to be away from any dogs in the home for safety and comfort.

Avoid Negative Introductions

This process should last around 4-5 weeks. It’s better to introduce your pets to each other gradually to avoid prolonged fear or aggression between the pets. You can expect mild forms of these behaviors which is normal, however, don’t let them worsen or move to the next step in the process before it is resolved. If either animal becomes fearful or aggressive, separate them, and restart the introduction process.

Our 5 Week Plan for Slow Cat to Dog Introductions

To help make cat to dog introductions more manageable, we’ve broken the process into weekly milestones that gradually build trust and familiarity between your pets. Each phase focuses on small, controlled steps—starting with complete separation and moving toward supervised interaction. This weekly breakdown offers a structured approach that allows both your cat and dog to adjust at their own pace, reducing stress and setting the foundation for a peaceful coexistence. Whether you’re dealing with a curious dog or a cautious cat, following this timeline can make cat to dog introductions more successful and less overwhelming.

Week 1

Secure the cat in a separate room the dog(s) cannot go into. This room should also serve as the area in which the cat will acclimate to their new enviornment. The dog(s) and cat will not meet or see each other until the second week (or longer) so that the cat has time to get used to the new house first and also get used to the scent of the dog(s).

Week 2

To begin the introduction process & allow for the cat to gain a more thorough smell the dog(s), you can rotate “free” time in the house by kenneling or putting your dog in a secured closed off room and then allowing the cats loose in the house.

Week 3

Put the dog(s) on leash and bring the cat into the same. room using a larger dog crate across the room. If you have any other dogs they should be out of the room and the process should be done one dog at a time. Reward your dog and your new cat for staying calm while the dog is across the room as well as your new cat. Do not move the dog any closer yet. You want to be able to get your cat’s attention in the presence of the dog and reward the cat any time they look away from the dog. and especially if the cat looks at you! Constantly praise both animals if they are remaining calm.

If the dog lunges or gets over excited, say “no” or “uh uh” and squirt him with the water bottle across the top of his head. Be sure to reward your dog if they choose a calmer behavior afterwards. Your cat is allowed to look at the cat but should be heavily rewarded for choosing to look away from the cat! If your dog is showing appropriate/ calm behaviors from across the room, begin to move closer and repeat the process. Only choose to move closer after your dog has successfully shown only positive behaviors at the previous distance 3 sessions in a row.

***If your dog is still showing too much interest or aggressive type behavior around the cat you should consult with a professional to evaluate the situation.

Week 4

Assuming your new dog is remaining calm around the cat and you have moved closer in proximity to the cat in the crate, you will start these exercises over again with the cat out of the crate. Start with your dog on leash across the room with the cat loose on the other side. You may need a friend to help hold or coral your cat to stay in the general area. This will look different to your dog since the cat is outside of the crate and can move more freely and normally. A common trigger for dogs is when the cat runs across the room so be sure to heavily reward your dog if the cat does move quickly or jumps up on something and your dog remains calm and quiet. Work up to a closer proximity to the cat but not allowing the cat to approach the dog or for the dog to have access to the cat.

Week 5

If the dog is doing well on leash and is responsive to you around the cat you can try him loose with the cat. Keep a leash on your dog but allow it to drag on the ground beside them like an extended handle that you can step on or quickly pick up if you need to interrupt or stop your dog. They are supervised the entire time and you are watching for any inappropriate behavior.

Allow your cat to give appropriate warnings like hissing or swatting to indicate that he needs space. Your dog should respond to this by moving away, reward him when he does this. If your dog does not understand the cat’s warning or thinks that it is play, help your dog by calling him away or guiding him away with the dragging leash. Continue to reward your dog for relaxed behavior and for any time that your dog looks at the cat but then chooses to look or move away.

Reminders

Even dogs that respect cats indoors may chase or lunge toward cats outdoors so be very careful having your dog and cats in the backyard together. This is a general time frame and you may need to add more time to the process if you are having a hard time reading the new dog. *New dogs and cats should not be left alone together for the first 6 months you have the dog.

You are still getting to know your new dog and what he/she will do in every circumstance. Crating is ideal when you aren’t around. The cat can become more accustomed to the dog while the dog is crated as well which will help in the long run.
