Measure the chest
With your dog standing, measure around the widest part of the chest, just behind the front legs. Keep the tape snug, not tight.
Match the size range
Large fits a 60–70 cm chest. XLarge fits a 70–80 cm chest. Use the measurement, not breed or weight—dogs of the same breed and weight can have different proportions.
