Introducing a new cat to a dog: a 14-day playbook

Rushing introductions is the #1 reason cat-dog households fail. A patient 14-day plan turns this into the easy intro it can be.

Days 1–3: Separation + scent

• New cat lives in one room with their own litter, food, water. Door stays closed.
• Swap a blanket between the cat's room and the dog's space. Both pets sniff the other's scent without contact.
• Watch the dog's body language at the door. Calm sniffing is good. Whining, scratching at the door, or stiff posture is your cue to slow down.

Days 4–7: Sight, no contact

• Use a baby gate or cracked door. 5–10 minute supervised sessions.
• Dog on leash. Reward calm focus on you — not the cat — with treats.
• End every session before either animal escalates. Short and positive beats long and stressful.

Days 8–11: Same room, leashed

• Dog on a relaxed leash. Cat free to approach or retreat.
• Give the cat vertical escape routes — a cat tree or shelves. The cat needs to control distance.
• No forcing contact. Let the cat sniff the dog if they want.

Days 12–14: Off-leash, supervised

• Only if every prior session has been calm.
• Keep sessions short. Always supervised. Feed them on opposite ends of the same room — shared positive experience.

Red flags — pause and call a behaviorist

• Dog fixating with stiff body, hard stare
• Cat hissing or swatting beyond first session
• Either animal can't eat in the other's presence after 10 days

Long-term setup

• Cat litter and food on shelves the dog can't reach
• Quiet spaces for the cat to retreat
• Never leave them alone unsupervised until you've had 4 weeks of conflict-free time together
