Lupine sizes its step-in harness by girth range in three strap widths. The product page lists six ranges, and they overlap, so this chart is a map of the options more than a strict size ladder.

Before you order
Lupine sizes by girth. Measure around the widest part of the chest, just behind the front legs.
Different brands cut different sizes, so a Medium here is not a Medium elsewhere. Match the chest number every time. The fit check takes a minute once it arrives.

Questions
What size Lupine eco step-in harness should I get?
Match your dog's chest girth to the chart on this page. Lupine's ranges overlap by design and come in three strap widths. The sizing guide link on the product page says which width goes with which range, so check it before ordering.
Why are Lupine sizes just numbers?
The product page names each option by its girth range instead of S, M or L, and offers 1/2 in, 3/4 in and 1 in strap widths. Pick the range that holds your dog's chest, then the width on the sizing guide.
How do I measure chest girth?
Stand your dog and wrap a soft tape around the widest part of the ribcage, just behind the front legs. Keep it snug, with room for two fingers.
