What size crate for a cockapoo puppy? (UK)

Search this question and you get the same answer everywhere: buy a 30-inch crate. For most British cockapoos that is correct. For a meaningful minority it is wrong, and the pages giving the advice rarely say which one you have.

The reason is simple, and it is the whole article: a cockapoo is not one size of dog.

Why the breed name tells you almost nothing

A cockapoo is a cocker spaniel crossed with a poodle. Poodles come in three sizes, so cockapoos come in at least three sizes, and the gap between the ends is not subtle.

Type	Adult height	Adult weight
Toy	25–30 cm	3–5.5 kg
Miniature	30–40 cm	6–8 kg
Standard (or maxi)	up to 45 cm	8.5–11 kg

A standard cockapoo can be half again as tall as a toy and roughly twice the weight. No single crate serves both.

The useful fact for British buyers is that cockapoos here are most commonly bred from a miniature poodle. That is why “30 inches” is the stock answer, and why it is right more often than not. The average cockapoo lands around 36–38 cm tall and 9–11 kg.

But “more often than not” is a bad standard when the thing costs sixty pounds and your puppy sleeps in it every night.

Ask the breeder one question

Before you buy anything, ask which poodle was used — toy, miniature or standard. A decent breeder answers immediately, because they chose the pairing.

If you cannot ask, because the dog is a rescue or the breeder has gone quiet, look at the parents’ weights if you have them. Failing that, wait. At twelve weeks you will have far better information than any chart can give you, and a cardboard box and a blanket will get you through the first fortnight.

The measurement that actually decides it

Crate size is sold by length in inches, which is why everyone talks about length. For a cockapoo, height is what catches people out.

A cockapoo is leggier than its weight suggests — the poodle side gives it proportions a cocker spaniel does not have. A dog that fits a 30-inch crate comfortably on length can still have to duck to sit upright in it.

So measure both:

Length. Nose to the base of the tail, with the dog standing. Add 5–10 cm.

Height. Floor to the top of the head while the dog is sitting, not standing. Sitting is taller. Add 5–10 cm.

Round up to the next crate size. British crates step 24, 30, 36, 42 and 48 inches, and that figure is the crate’s length.

If you are buying before the puppy arrives, measure the parents instead and assume the puppy lands between them.

So which one, in practice

Toy cockapoo — 24in. Only if you are confident the dog is genuinely toy-sized. This is the least common of the three in the UK, and the size people most often get wrong in the optimistic direction.

Miniature cockapoo — 30in. The right answer for most British cockapoos. Adult height around 30–40 cm leaves comfortable headroom in a 30-inch crate, and the length is generous.

Standard cockapoo — 36in. At up to 45 cm standing, sitting height gets close to the internal height of a 30-inch crate. A dog that has to lower its head to sit will not settle, and a dog that will not settle tells you about it at four in the morning.

Genuinely unsure — 36in with a divider. Too big is a solvable problem; too small is not. This is the only case where I would spend the extra.

Buy for the adult dog, and use the divider

A cockapoo puppy is tiny and reaches adult size in under a year. If you buy for the puppy you buy twice.

Instead, buy the adult size and use the divider panel to shrink the usable space, moving it back as the dog grows. This is not a nicety. Space is precisely what removes a puppy’s instinct not to soil where it sleeps — give a ten-week-old the run of a 36-inch crate and it will toilet at one end and sleep at the other, and your house-training stalls for a month.

If a crate you are looking at has no divider, that is a reason to look at a different crate, not a reason to buy two.

Where the standard advice goes wrong

“30 inches for every cockapoo.” It is right for the common case and presented as though there were no others. The advice is not wrong so much as incomplete, and the part it leaves out is the part that costs money.

“Buy small, they like feeling enclosed.” True for adults who are already house-trained, and the source of a lot of returned crates. A dog that cannot lie fully stretched on its side will not sleep properly in it.

American sizing charts. Most of what ranks for this question is written for the US market, where standard-poodle crosses are more common and the crates on sale are different. British stock steps in the sizes above; American guidance often does not map.

Three things to check before you pay

The door. Single, double, or a sliding door that does not swing out into the room. In a narrow British hallway or a small kitchen, a sliding door is often the difference between a crate that fits the space and one that does not.

The tray. A plastic tray that slides out will be cleaned more often than you expect in the first two months. Metal trays are louder and buckle.

The folded size. Most wire crates fold flat. If it will travel in a car or be put away in a cupboard, the folded dimensions matter as much as the open ones.

Who should not buy a crate at all

If your cockapoo already sleeps settled and house-trained in a room, and you have no plans to travel by car with them, you may simply not need one. A crate is a tool for house-training, safe containment and travel — not a rite of passage. Buying one out of obligation and leaving it folded behind a door is the easiest sixty pounds to waste on this list.

And if the plan is to crate the dog for long stretches during a working day, the crate is not the problem to solve. Cockapoos were bred from two companion breeds and are poor candidates for long stretches alone, crate or no crate. That is a question about cover and company, not about kit.
