Size advice and fit guide for dogs

The right fit matters for freedom of movement, comfort and everyday use. In this fit guide we explain which types of dog suit lumiies® well, how to measure correctly and how to find the right size without guesswork, including personal advice in the customer chat.

Why fit matters in dog apparel

Good dog apparel must not restrict. It should sit stretchy, comfortable and easy to move in, while running, playing, lying down and sleeping. The right size reduces rubbing, adds comfort and makes sure the function, warmth and protection, works reliably day to day.

Which dogs lumiies® suits well

Build

slim
narrow
long in the body
small to medium sized

Coat type and sensitivity to cold

little coat
no undercoat, or very little
dogs that feel the cold

Life stage and sensitivity

young dogs
older dogs
sensitive dogs
dogs that need extra warmth

Note: these are typical fit features, not a fixed rule. What counts are the measurements and the build. If you are unsure, our team helps in the customer chat.

Build and coat: what our patterns are made for

Freedom of movement instead of stiffness

Our products are designed to stretch. The aim is a feel like a second coat: comfortable, flexible and without stiff restriction, also on active dogs.

Warmth where it is needed

Dogs with little coat or no undercoat benefit in cool, cold or very cold weather. Your dog's behaviour always comes first: if he shivers or is visibly cold, apparel can make sense.

Typical dogs and breeds (examples)

lumiies® products are used most often by owners of these types of dog:

sighthounds
dachshunds
poodles
mixed breeds with a slim build

Note: examples, not a complete list. The measurements and the build always decide.

When standard sizes are difficult

Some dogs sit between two sizes or have a build that classic size charts struggle to cover. For that we offer several safe routes: measurement charts, the size configurator and personal advice in the customer chat.

Rule of thumb

If you are between two sizes, use the size configurator or the customer chat. You then get a clear recommendation based on your measurements.

How to measure correctly

Step 1: have your dog stand relaxed

Use a flexible tape measure. Your dog should stand calm and straight.

Step 2: take the relevant measurements

Take the values as our measurement charts and the size configurator set them out (for example back length, chest girth, depending on the product). It matters that you always measure at the same points.

Step 3: check the results

Compare the values with the measurement chart, or use the size configurator for a recommendation based on data.

Step 4: ask for advice if you are unsure

Real people advise in the customer chat. You can send measurements and photos, and our team helps you find the right size.

An honest limit

For very large or very stocky breeds, our current patterns may not fit well. In that case we say so honestly, and we are developing new patterns to cover more dogs in future.
