Puppies have very different nutritional needs from adult dogs — they need more protein, more fat, more calcium, and more frequent meals. Get this right during the first year and you set them up for a lifetime of good health.
Feeding Schedule by Age
| Age | Meals Per Day | Notes |
|---|---|---|
| 8–12 weeks | 4 meals/day | Tiny stomach, needs frequent feeding; watch for hypoglycemia in toy breeds |
| 3–6 months | 3 meals/day | Drop to 3 meals; keep on puppy formula |
| 6–12 months | 2–3 meals/day | Can shift to 2 meals; most small breeds switch to adult food at 9–12 months |
| 12–18 months | 2 meals/day | Transition to adult food for most breeds; large/giant breeds wait until 18–24 months |
How Much to Feed
Puppy food bags typically have a chart on the back based on expected adult weight. Use the expected adult weight column, not current puppy weight. If your puppy is a mixed breed, estimate based on similar breeds.
A rough guide for puppies eating quality puppy kibble (~400 kcal/cup):
| Expected Adult Weight | 8–12 weeks (daily) | 3–6 months (daily) | 6–12 months (daily) |
|---|---|---|---|
| Under 10 lbs | ¼ – ½ cup | ¼ – ½ cup | ⅓ – ½ cup |
| 10–25 lbs | ½ – 1 cup | ¾ – 1¼ cups | ¾ – 1¼ cups |
| 25–50 lbs | ¾ – 1½ cups | 1½ – 2½ cups | 1½ – 3 cups |
| 50–75 lbs | 1½ – 2 cups | 2 – 3 cups | 2½ – 3½ cups |
| 75–100 lbs | 2 – 3 cups | 3 – 4 cups | 3½ – 5 cups |
Transitioning to Adult Food
Switching too early or too abruptly can cause digestive upset and nutritional gaps. Here's how to do it right:
- Confirm your dog is ready — small breeds at 9–12 months, medium at 12 months, large at 12–18 months, giant at 18–24 months
- Mix 75% puppy food + 25% adult food for days 1–3
- Mix 50% puppy + 50% adult for days 4–6
- Mix 25% puppy + 75% adult for days 7–9
- 100% adult food from day 10 onward
Watch for soft stools or vomiting during the transition — a sign of moving too fast. Slow down if this happens.
My Puppy Won't Eat — What to Do
A puppy skipping a meal in the first few days home is very common — new environment stress. If it continues beyond 48 hours:
- Offer the same food at regular times; don't rotate through foods — this creates picky eaters
- Add a tablespoon of warm water or low-sodium chicken broth to increase palatability
- Make sure the food hasn't gone stale (store opened bags in airtight container, use within 6 weeks)
- Check for mouth pain — puppies teething may find eating uncomfortable
- If no food for 24 hours (toy breeds) or 48 hours (other breeds), call the vet
What Not to Feed Puppies
- Adult dog food — doesn't meet puppy calcium and protein requirements
- Homemade diets without vet guidance — very difficult to balance; common to create deficiencies
- Rawhides — choking hazard and potential Salmonella; use safer alternatives like bully sticks (supervised)
- Raw diets — immune systems are still developing; high risk of bacterial infection
- Table scraps — establishes begging behavior and can cause vomiting and pancreatitis
