Puppy Feeding Guide: How Much Is Too Much
Published May 2026 · 6 min read
My friend got a golden retriever puppy last spring. Named him Nugget. Cute name, right? Within three months Nugget looked less like a nugget and more like a potato. A very happy, very round potato.
Here is the thing about puppies. They are growing machines. A puppy needs roughly 2 to 3 times the calories per pound that an adult dog needs. But "roughly" is where people mess up. Because "roughly" becomes "just fill the bowl, he is a growing boy" and then you have a 4-month-old labrador who cannot fit under the coffee table anymore.
The Actual Numbers
A general rule vets use: puppies need about 20 kcal per pound of body weight per day for the first 4 months. After that, it drops to about 15 kcal per pound until they reach adult size. But here is the catch — they are gaining weight constantly. So you need to recalculate weekly. Yes, weekly.
I made a simple schedule for Nugget's owner. Weigh the puppy every Sunday morning. Before breakfast, after the morning bathroom break. Plug the new weight into the calculator. Adjust the food. It takes literally 90 seconds. Nugget is now a healthy 68-pound adult instead of the 45-pound butterball he was heading toward.
Common Mistakes
- Free feeding. Leaving food out all day teaches puppies to graze like cattle. Bad habit. Set meal times.
- Following the bag. Dog food companies want to sell food. Their feeding guides are usually 20% too high. Use a calculator instead.
- Treats do not count. Oh yes they do. Those training treats? 5 kcal each. Twenty treats = 100 kcal. That is a lot when your puppy only needs 600 total.
One last thing. Puppies act hungry constantly. It is not hunger. It is enthusiasm. They would eat a shoe if you put gravy on it. Do not let their sad eyes dictate portion sizes. Let math do it.
