Adult Dog Food Guide (1–7 Years)
Adult dogs need balanced nutrition to maintain ideal body weight and support their activity level. Size, activity, and reproductive status all influence calorie and nutrient needs.

Key Nutritional Points for Adult Dogs
Protein: 22–28% is generally appropriate
AAFCO minimum for adult dogs is 18%. Most quality adult foods fall between 22–28%. Active dogs may need higher protein. The first ingredient should always be a named animal protein (chicken, salmon, beef, etc.).
After neutering: reduce calories by 20%
Neutering reduces basal metabolic rate by 20–30%. Either reduce portions by 20% or switch to an indoor/neutered formula. Obesity is one of the most common post-neuter issues.
Grain-free is not necessary for most dogs
Grain allergies are much less common than protein allergies in dogs. The US FDA has investigated a potential link between grain-free diets and dilated cardiomyopathy (DCM). Unless a grain allergy is confirmed, grain-inclusive food is perfectly fine.
Weigh your dog every 2–4 weeks
Regular weigh-ins are the most effective way to catch weight changes early. If your dog's weight exceeds ideal by 10%+, reduce portions or switch to a light formula before obesity sets in.
Frequently Asked Questions
Q. When should I switch from puppy food to adult food?
Small breeds at 10–12 months, medium breeds at 12 months, large breeds at 18–24 months. Transition gradually over 7–10 days by mixing puppy and adult food in increasing ratios.
Q. Should I change my dog's food after neutering?
Yes, or at minimum reduce portions by about 20%. Neutering reduces metabolic rate significantly. Indoor or neutered-formula foods have lower calorie density and better satiety management, making them a good choice after the procedure.
Q. How much protein does an adult dog need?
AAFCO minimum is 18%, but most adult dogs thrive on 22–28%. The protein source matters more than the percentage — look for named animal protein (chicken, beef, salmon) as the first ingredient, not meat meal or plant protein concentrates.
Q. Is grain-free dog food better for adult dogs?
Not necessarily. Grain allergies are relatively uncommon in dogs. The first ingredient in grain-free foods is often a legume (peas, lentils), which the FDA investigated for a potential link to heart disease (DCM) in dogs. Unless your dog has a confirmed grain allergy, a grain-inclusive food is fine.
