Puppy feeding and growth
What should I feed a puppy during weaning?
Last updated 23 September 2026 · How we write and check this
Short answer
A puppy specific formula food, either a dedicated weaning gruel or regular puppy kibble soaked until soft, is the right choice during weaning. It is formulated for a growing puppy's higher protein, fat, and calorie needs in a way adult dog food and generic milk are not.
Why puppy specific food matters here
A weaning age puppy has intense nutritional needs relative to its tiny size, and adult dog food is simply not calorie or nutrient dense enough to support that. A puppy formula, softened to match the litter's chewing ability, is the appropriate choice from the very first weaning meal.
What to soak it with
Warm water is fine for softening kibble, though some breeders prefer a puppy milk replacer for the first week or two of weaning, since it adds a bit of extra nutrition and a familiar taste that can ease the transition away from nursing.
What to avoid during weaning
Cow's milk is not a good substitute for puppy milk replacer, since many puppies do not digest it well and it can cause diarrhea. Avoid introducing table scraps, treats, or anything outside a proper puppy formula during this sensitive digestive stage.
Key takeaways
- Use a puppy specific formula, softened as needed, from the first weaning meal onward.
- Warm water or a puppy milk replacer both work for softening the food.
- Cow's milk is not a suitable substitute and can cause digestive upset.
- Avoid treats or table scraps during this early, sensitive weaning stage.
