Pet Food Score - Petfood Advisor

Hello everyone,

I often see people comparing pet foods based on their carbohydrate percentage, even though many sources say that these values are not very reliable because carbs are usually calculated “by difference” from incomplete label data. This makes me wonder why carbohydrate levels are still used so much as a decision factor.

Could you explain why so many people continue to rely on estimated carbohydrate percentages when choosing pet food, despite the fact that these calculations can be inaccurate and do not distinguish between different types or qualities of carbohydrates? Do you think these carb-based comparisons are still useful as a rough indicator, or should they be considered too unreliable to base feeding decisions on?

Thank you in advance for your thoughts and experiences.
