Feeding a puppy fresh food is one of the best starts you can give them. But growth is also the life stage where nutritional mistakes carry the most weight, so it pays to slow down and get the fundamentals right.
Puppies eat more—a lot more
A growing puppy needs roughly two to three times the calories of an adult dog of the same weight. Instead of feeding a percentage of current bodyweight, most fresh feeders estimate puppy portions from expected adult weight, then adjust to the dog in front of them. A rough starting point is 5–10% of current bodyweight per day, split across three or four meals.
Calcium and phosphorus are non-negotiable
The single most important detail for large- and giant-breed puppies is the calcium-to-phosphorus ratio. Too much calcium during growth can interfere with healthy bone development. Aim for a ratio near 1.2:1 to 1.4:1, and don't add extra calcium supplements on top of a properly balanced bone portion unless your vet advises it.
Feed more often
Small stomachs and fast metabolisms mean puppies do best on frequent, smaller meals. Three to four meals a day under six months, dropping to two meals as they mature, keeps energy steady and digestion comfortable.
Introduce variety gradually
Puppies build tolerance to new proteins over time. Start with one or two gentle proteins, get stools consistent, then rotate in new options every week or two.
Because growth math is unforgiving, this is exactly the stage where a structured plan helps. Our daily calorie calculator gives you a starting point, and the FreshFed Feeding System handles the ratio math for you.
