How to measure
Measure length
From the tip of the nose to the base of the tail (not including the tail).
Add turn-around room
Add about 10 cm so the dog can stand and turn comfortably.
Don't oversize
Too large a crate undermines house-training โ use a divider for a growing puppy.
Check the door & height
Make sure the dog can sit without ducking; confirm the model's own chart.

Collar size is anchored to neck circumference, harness size to chest girth. Measure snug with a soft tape, then apply the two-finger rule (about +2-3 cm) so the collar is secure but comfortable. Breed figures are typical adult ranges and only a starting point โ individual dogs vary widely, and brand labels differ, so always measure your dog and check the specific product's size guide.
