The Best Harness for a Cockapoo: Sizing, Fit and Comfort
A cockapoo is a cross between a cocker spaniel and a poodle, and that second half is where the sizing question begins. A poodle can be a toy, a miniature or a standard, so a cockapoo can be anything from four kilos to twelve or more. Two dogs with the same breed name can easily be a size apart.
That is the difficulty with harness advice for cockapoos. There is no single answer, only a measurement and then an answer.
Here is how to find yours.
The Short Answer
| Your cockapoo | What we would suggest |
|---|---|
| Toy, 4–6 kg | Mario in size 1 or 2, or Gabriele XS |
| Miniature, 6–9 kg | Mario in sizes 2 to 4, or Gabriele S or M |
| Maxi, 9–12 kg and above | Gabriele M or L, or Franco in S |
Measurements are below. If you are unsure which size to take, send us the numbers and we will help you choose.
Why a Harness Suits a Cockapoo
There are two reasons, and the first is the coat.
A cockapoo's coat is wavy or curly, and it grows rather than sheds. That is part of the appeal — less hair on the sofa, and often easier on allergies — but it also means the coat mats. What matters is what sits against it. A coarse or textured strap, nylon in particular, works tangles into the coat over time. Smooth nappa leather slides against it instead. Cotton ribbon sits between the two, softer than nylon and gentler on the coat, and on a Y-shaped harness there is simply less material touching the dog to begin with.
The second reason is build. Cockapoos are active, curious and quick to follow a scent, which is the spaniel half showing. A harness moves the pull of the leash off the throat and onto the chest and shoulders, which makes for a steadier walk with a dog who has somewhere to be.
A collar remains a good choice for a cockapoo who walks calmly, and many do. Both work well. The harness is simply the more forgiving of the two on a curly coat.
Our Three Harnesses, and How Each Is Measured
They are built differently, so they are measured differently. Take the measurement that matches the one you are considering.
Mario is a step-in harness. Your cockapoo steps into it and you close it, so nothing passes over the head. It is a fixed shape rather than an adjustable one, which means the fit comes from choosing the right size. One measurement: the girth at the base of the neck, just in front of the front legs, where the harness sits once closed. Between two sizes, take the larger.
Gabriele is an H-shape. Two loops joined along the back, one at the neck and one around the ribcage, each with its own buckle. Two measurements, neck and chest, set independently. Between two sizes, take the larger.
Franco is a Y-shape. The chest strap forms a Y at the front, resting on the breastbone and leaving the throat clear entirely. It is made from striped cotton ribbon with natural leather ends, and it is fully adjustable through sliders and a side buckle, which gives it a wide range within each size. Two measurements, neck and chest. Because the adjustment range is generous, take the smaller size when you fall between two.
For any of them, measure snugly with a soft tape and leave room for two fingers between the tape and the coat. Take the measurement when the coat is at a normal length rather than immediately after a clip, since a fuller coat occupies more room.
If your cockapoo falls between two sizes, or if you are not certain which to take, write to us with the numbers and we will tell you which one to order.
Mario
| Size | Base of neck |
|---|---|
| 1 | 31–33 cm |
| 2 | 35–39 cm |
| 3 | 37–41 cm |
| 4 | 38–43 cm |
| 5 | 48–54 cm |
| 6 | 49–58 cm |
Gabriele
| Size | Neck | Chest |
|---|---|---|
| XS | 24–30 cm | 35–43 cm |
| S | 29–37 cm | 43–51 cm |
| M | 35–43 cm | 50–58 cm |
| L | 41–49 cm | 57–65 cm |
| XL | 49–57 cm | 65–73 cm |
Franco
| Size | Neck | Chest |
|---|---|---|
| S | 38–58 cm | 46–72 cm |
| M | 44–69 cm | 56–90 cm |
| L | 58–93 cm | 59–98 cm |
Franco begins at a 38 cm neck, so it is made for medium and larger dogs. For most cockapoos, S is the size in question.
The Best Harness for a Toy Cockapoo
A toy cockapoo comes from a toy poodle parent and usually settles between four and six kilos.
At this size the Mario in size 1 or 2 is generally the one. It is the lightest harness we make, and the step-in design suits a small dog who would rather not have anything lifted over their ears. It comes in six colours, from lazy taupe through to tangerine orange.
The Gabriele in XS is the alternative, covering a 24–30 cm neck and a 35–43 cm chest. It is the more adjustable of the two, which helps if your cockapoo is long in the body or narrow through the chest.
Franco is not made for a dog this size, and we would not recommend it here.
The Best Harness for a Miniature Cockapoo
This is the most common size, from a miniature poodle parent, usually six to nine kilos.
Mario covers this range across sizes 2 to 4. It is the quickest of the three to put on, which counts for something when you are heading out twice a day.
Gabriele in S or M gives the more precise fit. The two independent buckles let you set the neck and the chest separately, which matters on a dog whose proportions do not follow a standard chart. Cockapoos vary more than most, so that flexibility is worth having.
If your miniature is at the larger end, with a neck of 38 cm or more, the Franco in S becomes an option too. Measure first, since this is the size where it begins to fit rather than the size it was designed around.
The Best Harness for a Maxi Cockapoo
A maxi or standard cockapoo comes from a standard poodle parent and can reach twelve kilos or more, with a noticeably deeper chest. This is the size with the most choice.
Gabriele in M or L covers a 50–58 cm and 57–65 cm chest respectively, distributing pressure evenly across a larger frame while leaving the shoulders free to move.
Franco in S is the other answer, and for an active maxi it may be the better one. The Y-shape rests on the breastbone and leaves the throat clear, which suits a dog with real drive behind them, and the adjustable sliders let you tune the fit as the coat grows out between grooms. It is designed for dogs from cocker spaniel size upward, which a maxi cockapoo sits squarely within. It comes in green or blue stripes, with natural leather ends that darken and take on a patina with use.
Which Harness
Where more than one fits, the choice comes down to what you want from it.
Mario is the everyday harness: step in, close it, go. Light, quick, and in the brightest colours of the three.
Gabriele is the most formal, with two adjustable buckles and contrast stitching, in saddle brown, corvine blue, cherry or noir. It takes a moment longer to fit and holds that fit most precisely.
Franco is the most casual and the most adjustable, in striped cotton ribbon with untreated leather ends and silver hardware. It is also the one that changes most with wear, since the leather darkens over time.
Mario and Gabriele are handmade in Italy from smooth nappa leather. Franco is made in Italy from Italian cotton ribbon and natural leather. All three have a matching leash.
Leashes
Each harness pairs with a leash from the same collection.
The Gabriele adjustable leash extends to 240 cm and can be worn across the body, which is useful on a longer walk or when you would rather have your hands free.
The Franco leash runs to 265 cm with multiple fastening rings, so it can be worn crossbody or held conventionally, and shortened or lengthened as you go. It is the most versatile of the three.
The Ferdinando braided leash is the heaviest and most traditional, in braided nappa with the same hardware as its collar. It suits a cockapoo at the larger end of the range.
Collars
A collar earns its place even if your cockapoo walks in a harness, if only to carry an identification tag.
The Ferdinando braided collar is made from braided nappa leather with a rounded profile. That shape is deliberate: a rounded collar sits more softly against a coat than a flat one and is less likely to press a line into it, which on a cockapoo's coat is worth something. It runs from the smallest sizes up to a 50 cm neck and can be engraved with your dog's name or a telephone number.
The Franco collar is the lighter, more casual option, in the same striped ribbon and natural leather as the harness. It comes in four sizes, measured on the neck.
A Note on Coats
A cockapoo's coat needs regular grooming, and most people settle into a schedule of every six to eight weeks with brushing in between. Where a harness sits, it is worth brushing underneath the straps as part of that routine, since that is where tangles tend to start.
The coat also changes what you measure. A cockapoo measured the week after a clip and the week before the next one can be a centimetre or two apart, so take the measurement somewhere in between if you can. This is one of the quiet advantages of an adjustable harness: the Gabriele and the Franco can both be let out or taken in as the coat grows, without changing size.
Common Questions
What size harness does a cockapoo need?
It depends on which poodle they came from. Toys usually take a Mario in size 1 or 2, or a Gabriele XS. Miniatures take a Mario in sizes 2 to 4, or a Gabriele S or M. Maxis take a Gabriele M or L, or a Franco in S. Measuring is the only reliable way to know.
Is a harness better than a collar for a cockapoo?
For walking, usually. It takes pressure off the throat and is gentler on a curly coat. For carrying a tag, a collar is the simpler option, and many cockapoos wear both.
Do harnesses mat a cockapoo's coat?
A coarse or nylon strap can, over time. Smooth nappa leather and soft cotton ribbon are much gentler, and a Y-shaped harness has less material against the coat than the other shapes. Brushing under the straps as part of regular grooming takes care of the rest.
What is the difference between a step-in, an H-shaped and a Y-shaped harness?
A step-in has a fixed shape the dog steps into and is sized on one measurement. An H-shape has separate neck and chest loops that adjust independently. A Y-shape rests on the breastbone and leaves the throat clear, and is usually the most adjustable of the three.
Can a cockapoo wear the same harness as a poodle?
Yes, and the sizing logic is the same, which is unsurprising given the shared parentage. Our guide to harnesses for poodles covers it in more detail.
