Crate for a 6-week-old Chihuahua

Crate training works really well when the crate becomes a genuinely positive space — but the size and type of crate matters far more than most people realise, and so does how you introduce it. A crate that's too large for a tiny puppy can actually undermine the whole process. To point you in the right direction: what breed and age is your dog, are you starting from scratch or trying to undo a bad association, and is this for home use or travel?

Six weeks is very young — and Chihuahuas at that age are genuinely tiny, often under 500g. That's where standard dog crates immediately become a problem. Even with a divider inserted, the smallest panel on most wire crates still leaves far too much space, and a puppy that small can slip through or get trapped in the gaps. What you actually need is something closer to a small animal or rabbit enclosure — enclosed enough to feel secure, with bars spaced tightly enough that she can't squeeze through or catch a paw. Has she had any crate exposure at all yet, or is this day one?

Perfect — you're in the best possible position, no bad habits to unpick. For a Chihuahua this age and size, I'd recommend the Ferplast Rabbit 46 cage. It sounds like an odd choice but it's genuinely the right tool here: the internal dimensions are compact enough to feel den-like for a tiny puppy, the bar spacing is around 1.8cm so there's no risk of her squeezing through, and it has a solid tray base that's easy to clean. You can line it with a small fleece and a covered heat pad, and she'll settle into it quickly because the scale is actually proportionate to her. A standard puppy crate — even the smallest — would feel like an aircraft hangar to her right now and make the whole process harder. The Ferplast Rabbit 46 is widely available on Amazon UK, usually under £30, and it'll serve you through the first few months. Once she's fully grown you can reassess — adult Chihuahuas are still small enough that you won't need much more than a small dog crate, but that's a decision for later.

Keep it simple at this stage. A small fleece or blanket — ideally one that came with her from the breeder and smells familiar — makes a real difference in the first week. A covered low-wattage heat pad underneath part of the bedding helps because she can't regulate her temperature well yet at six weeks. Avoid toys with squeakers or loose parts she could choke on. A small stuffed toy is fine. Don't put food or water inside the crate overnight — she should have a last feed close to bedtime, but water in the crate tends to get knocked over and makes the bedding wet, which undoes all the positive association work. Keep the door open during the day initially so she can wander in and out freely, and only start closing it for short periods once she's choosing to go in on her own.

At six weeks, an hour is about the maximum during the day — her bladder control is minimal and she'll need to toilet very frequently. Overnight is slightly different because puppies naturally sleep longer and their systems slow down, but you should still expect at least one night wake for a toilet trip. The rule of thumb people use is one hour per month of age plus one, so at six weeks that's roughly 90 minutes absolute maximum before she'll need out. Don't push it at this stage — accidents in the crate create a negative association that's genuinely hard to fix later. Short, successful sessions beat long ones every time.
