Proper sizing of products is crucial to the safety and comfort of the dogs and cats wearing them. However, we understand it can be a confusing process for pet owners. Use these visuals as a guide for how to measure dogs properly for a collar, harness, or vest.
How to Measure for Collars and Harnesses
A. Neck: Collars should sit up higher on the neck, so measure here when determining collar size.
B. Girth: Wrap the tape measure around the broadest part of the dog’s rib cage.
For optimal fit, ensure that there is enough space for two fingers to easily slide between the collar or harness and your dog’s neck or chest.
Measure first!
Dogs come in all different shapes and sizes and therefore, each has a unique fit. The best way to fit them properly is by using their measurements first and their weight range second.
