Measurements are the size of the shirt - not the size of the dog.

To measure:

Loosely wrap a string or ribbon around your dog's chest as loose as you want the tank to fit.
Measure the string or ribbon and divide in half.
Compare the measurement with Column A (width) on the chart. This is the size your dog should wear.
If your dog has a deep chest, thick hair or you want a longer length, you will need to order the next size.
