What is the chest measurement?
YOUR NUMBER
Estimated from weight with an early model. A tape measure is more reliable, so check before you order.
Questions
What do I type in?
Your dog's chest girth: the distance around the widest part of the ribcage, just behind the front legs. If you only know the weight, switch to weight and we will estimate it.
How do you know which size fits?
Each brand's own chart, copied from its page and checked 2026-10-10. We match your number to the chest range printed there. Where two sizes both cover it, we say so and repeat the brand's own advice.
Why only a few brands?
We add a brand only after reading its chart directly from the maker's page. More are on the way.
