Dachshund puppy with hostile cat: safe intro tools

A 9-week-old Dachshund arriving into a home with a hostile cat is genuinely one of the trickier multi-pet situations — not because it can't work, but because the first few weeks set the tone for the whole relationship, and getting the physical setup wrong can make a cat's hostility much harder to walk back. The list of 'essential' puppy products is massively inflated by marketing, by the way — you probably need far less than most guides suggest, and buying the wrong things now is expensive and often wasted. Before I point you toward anything specific, can you tell me: what breed is the puppy, how old are they, and when are they coming home?

That's really helpful context. A cat who has already shown he'll escalate to swatting is telling you he needs to feel genuinely in control of his own space — not just tolerated, but properly protected from the puppy. And a 9-week Dachshund is small enough that an angry swat to the face is a real concern. The single most useful thing you can buy right now isn't a crate or a puppy pen — it's a pressure-fit pet gate with a built-in cat flap. This lets your cat move freely through the whole house on his terms while the puppy stays confined to a puppy-safe zone. The cat can observe from a distance, approach when he chooses, and retreat instantly. That voluntary control is what slowly converts hostility into tolerance.

The one I'd point you to is the Coziwow Extra Tall Pet Gate with Cat Door — it's available on Amazon UK and it's the right tool for this exact situation. It's 90cm tall, which matters for a Dachshund because they're low and won't be leaping it, and the small cat-flap opening at the bottom is sized so your cat can pop through easily but a puppy absolutely cannot follow. It pressure-mounts without drilling, fits most standard doorways, and is sturdy enough that a determined terrier-type wouldn't knock it. For a Dachshund puppy it's genuinely overkill in the best way. Set it in a doorway between two rooms so your cat always has a clear escape route — that alone will reduce stress on both animals enormously in the first few weeks.

Yes — and none of it requires buying anything. For the first few days, don't let them see each other at all. Let the cat smell the puppy under the gate and through the door gap; that scent exchange is doing real work. Feed both animals on opposite sides of the gate so they start associating each other's smell with good things. Only progress to visual contact once the cat has stopped hissing at the smell alone, and when you do, keep the puppy on a lead so she can't rush toward him. Your cat needs every interaction to feel like his choice. Rushing it is the main thing that goes wrong — but with the gate doing the heavy lifting, you have time to go slowly.

Good — you're already ahead of most people just by taking the cat's perspective seriously. The gate is the one thing worth buying before she arrives. Everything else can wait until you see what you actually need. Good luck on Saturday — Dachshunds are brilliant, and cats do come around.
