Choosing a dog
What should I look for in a dog if I already have a cat?

Short answer
Look for a dog with a naturally lower prey drive and a track record, where known, of calm behavior around cats specifically, rather than assuming any dog will adjust fine. Ask a breeder or shelter directly whether the dog has lived with or been tested around cats before, and plan for a slow, carefully managed introduction regardless of the dog's apparent temperament, since first impressions can be misleading.
Why prey drive matters more than breed alone
Some breeds were developed for roles that involve chasing or catching small, fast moving animals, which can translate into a stronger instinctive reaction to a cat's sudden movement, though individual variation within any breed is significant. Ask directly about a specific dog's reaction to cats, ideally based on real observed behavior rather than a general assumption based on breed.
What a good introduction actually looks like
A successful introduction is gradual, often taking days to weeks, starting with the two animals separated by a door or gate so they can hear and smell each other before any direct visual contact, then progressing to controlled, supervised meetings only once both seem calm. Rushing this process is one of the most common reasons introductions go poorly.
Setting up your home to support the transition
Give your cat safe, elevated spaces the dog cannot reach, and keep the dog on a lead during initial supervised meetings so you can intervene calmly if needed. A consistently calm, unhurried approach across several weeks gives both animals the best chance of a comfortable, lasting coexistence.
Signs the introduction is genuinely going well
Look for relaxed body language from both animals, such as a cat choosing to stay in the room rather than fleeing, and a dog that shows calm curiosity rather than fixed staring or lunging, as reliable signs the introduction is progressing safely toward a comfortable coexistence.
Patience through this early stage tends to pay off with a far more relaxed household in the months that follow.
Key takeaways
- A lower prey drive and known calm behavior around cats matter more than breed alone.
- Ask specifically whether a dog has been observed around cats before, if known.
- A gradual introduction over days to weeks works far better than rushing initial meetings.
- Give your cat elevated escape routes and keep early meetings controlled with a lead.
