Body Condition Scoring (BCS) for dogs and cats

Body Condition Scoring (BCS) is a quick and easy way to check the weight of your dog or cat. It is a simple and quick check that can be done twice each month. Our picture guide below explains how to check your pet. It describes what you should be looking for and feeling, and what the results mean. It is useful to keep a record of each date and the corresponding BCS to monitoring your pets body condition over time. This will help to ensure that they maintain a healthy weight.
