How to measure your dog for a Ruffwear dog harness:

Chest girth: The chest girth is the most important measurement for sizing a Ruffwear harness. To measure your dog's chest girth, wrap a tape measure around the widest part of your dog's chest, just behind the front legs.

Here are some additional tips for measuring your dog for a Ruffwear dog harness:

• Make sure your dog is standing up straight when you take the measurements.
• Use a soft tape measure that will not pinch your dog's skin.
• If your dog is between sizes, choose the larger size.
