One of the most common and important questions dog owners ask is, “how much food should I feed my dog?” Feeding the right amount is essential for maintaining a healthy weight, supporting growth, preventing disease, and ensuring your dog lives a long, active life.
Feeding too little can lead to nutritional deficiencies, low energy, and weakened immunity. Feeding too much can cause obesity, joint problems, heart disease, and reduced lifespan. The challenge is that there is no single answer that fits every dog.
This guide breaks down everything you need to know about how much food to feed your dog, including age, size, breed, activity level, food type, and how to tell if you’re feeding the right amount.
