Before you order
Mighty Paw measures the neck and the chest at the widest point under the armpit, with the dog standing.
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 Mighty Paw dog sport harness should I get?
Match your dog's chest girth to the chart on this page. Mighty Paw says that if your dog is in between sizes, choose the larger size.
Do the Sport and Vehicle Safety harnesses use the same sizes?
No. The ranges differ, as the two charts above show. A dog can be a Medium in one and a Large in the other, so use the chart for the harness you are buying.
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.
