Measuring your dog is the best way to get a harness to fit your baby. 

If your dog's chest or neck measurements are at the edge of a size range, I can adjust the harness length for free.

To ensure the best fit, please provide the "neck base" and "chest girth" measurements. Keep in mind that "neck base" (line B) is different from "neck girth" (line A). When crafting your dog's harness, I always add an extra inch to the neck base measurement. For example, if your dog's neck base is 14", I'll make it 15" on the harness for a comfortable fit.

So, please measure your dog snugly, or the harness might end up too large.

I've attached a photo showing how to measure your dog!

If you already have a similar harness that fits well, you can measure it, and I can match those measurements for the new one. :)
