You should measure with a tape measure, but not too tightly or too loosely. Ideally, you should be able to fit your fingers between it and your pet. Always keep in mind that the measurement you get should not be at either extreme of any size. Try to ensure that it falls more or less in the first half of one of the ranges in the table. If it falls towards the upper end, we recommend choosing the next size up.
- Neck: Neck circumference. Place the tape measure around the neck as shown in the image.
- Chest: Chest circumference. Place the tape measure around the dog's chest, behind the front legs.
- Length: Back length. Place the tape measure from the base of the tail to the base of the neck (the base of the neck is the point where it connects to the back or back), as shown in the image.
