Grab that tape measure!
Measure your pup around their neck, right where the collar will sit. For a harness you will also need to measure their chest circumference by taking the measurement just behind their two front legs.
The tape measure wants to be snug, but not too tight. A two finger width gap is sufficient breathing room.
