How to read a pet food label

Look for a 'complete and balanced' AAFCO (US) or FEDIAF (EU) statement — this means the food meets nutritional standards for a specific life stage. Named protein sources ('chicken', 'salmon') beat vague 'meat by-product'. First 3 ingredients matter most.

Choosing a diet type

Dry (kibble): convenient, affordable, dental benefit. Wet (canned): higher moisture, ideal for cats and picky eaters. Fresh/gently cooked: highly digestible, higher cost. Raw: potential benefits but bacterial risk — talk to your vet first.

Portion control and body condition

Over 55% of dogs and cats in developed countries are overweight. Weigh food (don't scoop by eye), account for treats (should be <10% of daily calories), and check body condition monthly — you should feel ribs easily without pressing hard.

Human foods that are toxic

Never feed: chocolate, xylitol (sugar-free gum), grapes/raisins, onions/garlic, macadamia nuts, alcohol, caffeine, raw dough. Cats are additionally sensitive to lilies, raw fish (thiaminase) and many essential oils. If ingested, call a pet poison helpline immediately.

Frequently asked questions

How do I know if my pet food is high quality?+

Look for a complete-and-balanced AAFCO or FEDIAF statement, named animal proteins as the first ingredients, and a brand that publishes feeding trials and manufacturing details.

Are grain-free diets healthier?+

Not automatically. The FDA has investigated a link between certain grain-free diets and heart disease (DCM) in dogs. Unless your pet has a diagnosed grain allergy, most vets recommend grain-inclusive diets from established brands.
