# Fit Guide
# 1 Take measurements
- Measure the back length from the shoulder blades to the start of the tail.
- The neck should be measured where it is widest.
This size is important for the length of the collar or chest harness as well as clothing.
- The chest-size should be measured at the widest part behind the front legs.
It will show you how big a coat should be and also the size of a chest harness.
If your dog has an in-between size, we recommend the larger size so that your pet will feel at ease and has ample room for movement. This rule is recommended for long-haired dogs as well.
