- When measuring for a dog step-in harness, you are looking to measure the chest (A) where the step-in harness should fit.
- Below we provide an indication of size by breed, but please do not take it as correct for all breeds. Dogs come in all shapes and sizes, the weight provided is just a guide and to highlight the strength test limits for our harnesses.
- Two finger rule, it is a good method to leave some space around the chest when fitting the harness. This will make sure the harness is comfortable and can be adjusted.
