Dog Anxious Around New Cat? Here's What to Do

Start with a Controlled Introduction

When introducing a dog to a new cat, never rush the process. The cat should be brought into the home in a carrier, placed on the floor in the same room as the dog—but not directly released. This prevents the dog from reacting to a sudden movement or perceived "prey." The dog should be on a leash and training collar so you can control their behavior at all times. This setup helps avoid the dog seeing the cat as “live bait,” which can trigger anxiety or overexcitement.

Let the Cat Set the Pace

The cat may initially hide or flee after being released from the carrier. This is normal and expected. Allow the cat to explore and feel safe in her new space. The dog should not be allowed to chase or corner her. Instead, let the cat become familiar with the dog’s scent and presence over time. This desensitization process helps reduce fear and confusion for both animals.

Use Treats to Build Positive Associations

While the dog is on a leash, use treats to redirect their focus from the cat to you. When the dog remains calm near the cat, click or say “Yes!” and reward them with a treat. Repeat this until the dog no longer becomes overexcited or anxious when the cat is present. This teaches the dog that the cat’s presence means good things—like food and attention from you—rather than danger or stress.

Keep the Dog Leashed Until Confident

Even if the dog seems calm, do not remove the leash until you are certain they won’t react suddenly. Some dogs may appear relaxed but still have the instinct to chase or lunge. Keep the dog leashed during all early interactions. Only consider off-leash time when the dog shows no signs of aggression, fear, or overexcitement—such as barking, lunging, or cowering—and the cat is relaxed (not hissing, crouched, or ears pinned back).

Give the Cat Time to Adjust First

Before any direct meeting, have the dog in a separate room when the cat arrives. Bring the cat into a spare room with a litter box, food, water, bed, and scratching posts. Let the cat settle in for several days. This gives her time to explore her new environment without pressure. Only after she appears calm and comfortable should you begin controlled, brief introductions with the dog.
