A guide to reading pet food labels

Pet food labels are legally regulated, which means there's more real information on them than the marketing suggests — you just have to know where to look.

Ingredients are listed by pre-cooking weight

This is the single most misleading part of a label. 'Fresh chicken' listed first sounds great, but raw chicken is roughly 70% water — once cooked, it may weigh less than the grain listed second. Weight order isn't nutrient order.

The guaranteed analysis is a floor and ceiling, not a fact sheet

Guaranteed analysis gives you minimums for protein and fat, and maximums for fiber and moisture — not exact values. Two foods with identical guaranteed analysis numbers can still have meaningfully different actual nutrient content.

Terms that sound regulated but mostly aren't

"Premium," "gourmet," and "natural" have little to no legal definition in most regions. "Complete and balanced," by contrast, is a real regulated claim tied to meeting specific nutrient profiles — that's the phrase actually worth looking for.

• Look for an AAFCO (or regional equivalent) nutritional adequacy statement — that's the real substance behind a label.
• "By-product" isn't inherently bad — organ meat is a by-product and is often more nutrient-dense than muscle meat.
• If in doubt, a vet nutritionist consult is worth it for pets with specific health conditions.
