Dog Size Guide for Wholesale Buyers
Measure your dog's neck, chest, and back length before choosing a size. Keep the tape snug, but leave enough room for two fingers.
How to measure your dog
Chest
Measure around the widest part of the chest, just behind the front legs.
Back length
Measure from the base of the neck to the base of the tail.

For wholesale buyers
- Use body measurements rather than breed or weight alone.
- Choose the larger size when your dog falls between sizes.
- Check each product page for item-specific measurements.
- For harnesses, make sure the chest strap does not rub behind the front legs.
- For raincoats and fitted gear, compare chest, neck, back length, and coverage style.
