When should I switch my puppy to adult dog food?

Most small and medium breeds are ready to transition to adult food around 12 months old. Large breeds typically stay on a large-breed puppy formula until 12-18 months, and giant breeds sometimes until 18-24 months. The transition from puppy to adult food should be gradual -- mixing increasing proportions of the new food over about a week helps avoid digestive upset.

How many times a day should an adult dog eat?

Two meals a day is the standard recommendation for most healthy adult dogs. It distributes the daily calorie load, helps with appetite management, and for large and deep-chested breeds reduces the risk of bloating from one large meal. Some owners feed once a day, which is generally fine for healthy adult dogs if they tolerate it well.

At what age do dogs need fewer calories?

Calorie needs typically start declining gradually in middle age (around 4-7 years for most breeds) as activity levels naturally decrease, and decline more noticeably in the senior years. The exact timing varies by individual dog and breed size -- recalculating periodically based on current weight, activity, and body condition gives the most accurate picture.

Should I feed my senior dog a senior-specific food?

Not automatically. Whether a senior food is appropriate depends on the individual dog's body condition, bloodwork, and any health conditions -- it's worth discussing with your vet rather than switching at a fixed age. Some senior dogs do well on a continued adult formula; others genuinely benefit from the lower calorie density or added joint support of a senior-specific product.

Is it normal for a dog to eat less as it gets older?

A gradual, modest decrease in appetite can be a normal part of aging as activity and metabolic rate decline. A more noticeable or sudden drop in appetite, or any weight loss that isn't intentional, is worth a vet check -- appetite changes in senior dogs are sometimes the first sign of an underlying health issue.
