Dog food: how to choose well

Choosing a dog food is a wall of bags, claims and cartoon wolves. Strip away the marketing and the decision gets simpler: complete nutrition, the right calories for your dog, ingredients from a maker who employs nutritionists and runs feeding trials, and a price per month you can sustain for the dog's whole life.

The five checks that actually matter

1. Complete and balanced, stated properly. Look for a nutritional adequacy statement saying the food is formulated to meet AAFCO profiles (or FEDIAF in Europe) for your dog's life stage, or that it passed feeding trials, which is the stronger claim.
2. The maker, not the mascot. Brands that employ board certified veterinary nutritionists, own their factories and publish quality testing are safer bets than brands built on advertising.
3. Calories per cup, in writing. Foods range from 300 to over 450 kcal a cup. Without this number you cannot feed a consistent ration or compare costs honestly. Our feeding calculator does the math from your dog's weight.
4. Life stage fit. Puppies, especially large breed puppies, need controlled calcium and calories for slow, steady growth. Seniors often need joint support and fewer calories. All life stages foods are a compromise.
5. Your dog's evidence. Steady weight, good coat, normal stools and enthusiasm at the bowl beat any ingredient list debate. Change foods slowly over a week to avoid stomach upsets.

What it costs

Food is the biggest running cost of a dog's life. Our food expense calculator shows monthly and yearly figures by size and tier, from budget kibble to fresh subscriptions, with the method published. Breed profiles show the food cost for that breed on the same page as its insurance cost, because the two belong together in a budget.

Grain free, raw and home cooked, briefly

Grain free diets were linked by the FDA's investigation to a rise in dilated cardiomyopathy in some dogs; the research continues, and it is a conversation to have with your vet rather than a label to trust. Raw diets carry real bacterial risks for dogs and households. Home cooked diets are almost always nutritionally incomplete unless formulated with a veterinary nutritionist. None of these are automatic disqualifiers; all of them deserve more than a slogan.
