Dog Clothing Size Guide – How to Measure Your Dog
A good fit in dog clothing starts with accurate measurements and the size chart for the specific garment. Measure your dog while standing naturally, then compare the measurements with the product-specific size chart.
Use a soft measuring tape and measure your dog while standing in a relaxed, natural position. Do not choose a size from body weight, breed or a general S–XL label alone.
What to measure
1. Back length
Measure along the back from the base of the neck to the base of the tail while your dog is standing naturally. Check the product’s own measuring diagram because the exact starting point can vary by garment design.
2. Chest girth
Measure around the widest part of the chest, behind the front legs. Keep the tape close to the body without pulling it tight.
3. Neck circumference
Measure around the lower part of the neck where the garment opening is intended to sit. Do not add a fixed amount unless the product instructions specifically require it.
4. Other measurements — when required
Some garments, especially overalls or more fitted designs, may require additional measurements such as leg length or another model-specific measurement. Use them only when they are requested in that product’s size chart.
Check the fit
- The shoulders and front legs should move naturally without the garment pulling or restricting movement.
- The chest area should not feel tight and adjustment points should sit securely.
- The garment should stay reasonably centred when the dog walks and turns.
- For overalls, check the movement and fit of all four legs.
- For raincoats and coats, check that the intended coverage is achieved without restricting movement.
Do not automatically choose the larger size. Compare all measurements requested for that garment and consider its construction and adjustment points. The product-specific size chart determines which measurements should be prioritised.
Size labels are not universal
A number such as 30, 40 or 50 — or a label such as S, M or L — does not have the same meaning across every brand and garment. Always use the actual centimetre measurements shown for the product.
Common measuring mistakes
- Measuring while the dog is sitting, lying down or stretching.
- Choosing the size mainly from body weight or breed.
- Adding fixed extra centimetres without checking the garment instructions.
- Assuming the same size label fits the same way across different products.
Use this guide to take the measurements correctly. Then compare them with the size chart and measuring instructions on the specific product page before ordering.
