Dry Dog Food

Puppy food is formulated for growth, with different energy and nutrient levels than an adult diet, and feeding an adult food to a growing puppy — or the reverse — is a common mistake worth avoiding. Adult maintenance diets make up the bulk of what most dogs eat day to day, while senior formulas are typically adjusted for a slower metabolism and, in some ranges, joint support.

Breed size matters too: small and toy breeds generally need smaller kibble pieces and more calorie-dense food relative to their size, while large breeds — particularly as puppies — benefit from a controlled growth rate to support healthy joint development.

Sensitive diets are typically built around a single named protein, which narrows down what a dog is actually eating and makes it easier to identify what does or does not agree with them. This is a genuinely useful starting point for a dog with a suspected food sensitivity, though it is not a guarantee against every reaction.

Grain-free diets replace cereal grains with alternative carbohydrate sources and suit dogs whose owners specifically want to avoid grain, though grain-free is not automatically better for every dog — it is one option among several rather than an upgrade that suits everyone.

Any change of dry food is best done gradually over several days, mixing increasing amounts of the new food in with the old rather than switching overnight, which reduces the chance of an upset stomach. Watching your dog's stools, appetite and coat over the following weeks is the best way to judge whether a new food genuinely suits them.

If a dog does not settle on a new food, or shows ongoing digestive upset, it is worth speaking to your vet rather than working through a long list of foods by trial and error alone.
