Steps To Measure a Dog for Harness

For an accurate measurement of your dog’s weight, use a suitable scale on a level surface. Encourage your dog onto the scale with positive reinforcement. Once your dog is settled, record the weight displayed on the scale.

Neck Girth

When measuring the neck, wrap measuring tape or string around the base of your dog’s neck where the collar usually sits. Ensure the tape is snug but not too tight. Record the measurement in inches.

Chest Girth

Wrap the measuring tape or string around the widest part of your dog’s chest, typically just behind the front legs. Keep the tape parallel to the ground and snug against the fur. Record this measurement accurately in inches.
