How often should an 8 week old puppy eat?

Puppies grow very quickly in their first few months of life, and proper nutrition is essential for their development. By 8 weeks old, puppies should be weaned off their mother’s milk and eating solid food regularly. So how often should an 8 week old puppy eat? Here is a quick overview of feeding recommendations for 8 week old puppies.

Quick Answer

An 8 week old puppy should eat 3-4 meals per day. The total amount will vary based on the puppy’s breed and size, but a good rule of thumb is to feed about 1/2 cup to 1 cup per meal.

How Much Should an 8 Week Old Puppy Eat?

At 8 weeks old, puppies have very fast metabolisms and need a lot of energy and nutrients to support their rapid growth. The exact amount to feed will vary based on breed, size, and activity level. As a general guideline:

  • Small breed puppies need 1/2 to 1 cup per day
  • Medium breed puppies need 1 to 1 1/2 cups per day
  • Large breed puppies need 1 1/2 to 2 cups per day

This total daily amount should be divided into 3-4 meals throughout the day. For example, a medium-sized puppy needing 1 cup per day could eat 1/4 cup at each of 4 meals.

High quality puppy food formulated for growth is recommended, and feeding amounts should be adjusted based on the calorie content of the specific food. Your veterinarian can help determine the ideal amount to feed your individual pup based on their health, breed, and development.

Growth Rate of 8 Week Old Puppies

At 8 weeks old, puppies are still rapidly growing and their calorie needs are very high. Their growth rate slows gradually as they mature, but 8-12 weeks is still considered the fastest growth period. During this stage, puppies should gain around 2-4 lbs per week on average. However, large and giant breed puppies need to grow a bit more slowly to avoid orthopedic problems. Here’s an overview of puppy growth patterns:

  • 0 -4 weeks: Triples birth weight
  • 4-8 weeks: Doubles weight from 4 weeks
  • 8-12 weeks: Gains 2-4 lbs per week
  • 3-6 months: Growth rate slows; gains around 10% of adult weight per month

Weighing your puppy weekly can help ensure they are growing at an appropriate rate based on their breed. Your veterinarian can advise you on your puppy’s optimal weight gain timeline.

How to Feed an 8 Week Old Puppy

Here are some tips for feeding an 8 week old puppy:

  • Choose a high quality puppy food and follow the feeding guidelines on the bag
  • Divide daily amount into 3-4 meals throughout the day
  • Use scheduled mealtimes rather than free-feeding
  • Make adjustments based on body condition; increase amount if too thin or decrease if overweight
  • Provide access to fresh water at all times
  • Transition new foods gradually over 4-7 days by mixing with old food
  • Discontinue feeding puppy formula or milk replacements

How Often Should an 8 Week Old Puppy Eat?

At 8 weeks old, most puppies should eat:

  • 3 scheduled meals per day, or
  • 4 smaller meals per day

Feeding smaller meals more frequently can help prevent digestive upset and keep energy levels steady. However, some puppies do fine with only 3 meal times per day. Observe your puppy’s appetite and energy levels, and adjust the frequency to keep them satisfied.

It’s best to establish scheduled meal times rather than leaving food out all day. Free-feeding makes it harder to monitor how much your puppy is eating. Just make sure there are no more than 4-5 hours between meals on your schedule. Small breed puppies may need more frequent feedings than larger breeds.

Nighttime Feedings

While some puppies need a late evening meal around 8-10 pm to avoid hypoglycemia, most 8 week old puppies should be able to sleep through the night without food. Just make sure your last feeding of the day takes place 3-4 hours before bedtime. Establishing good mealtime routines will help your puppy learn when to expect their food during daylight hours.

Important Nutrients for 8 Week Old Puppies

Some key nutrients 8 week old puppies need in their diet include:

  • Protein: for muscle growth and body tissue repair
  • Fat: for energy, nutrient absorption, brain development
  • Calcium and phosphorus: for proper bone growth
  • Iron: for healthy blood cell function
  • Vitamin A: for a healthy immune system and vision
  • Other vitamins and minerals: for metabolism, tissue growth, and disease prevention

High quality puppy foods are formulated with optimal nutrient levels. Avoid over-supplementing, which can lead to toxicity. And steer clear of poor quality foods, which won’t provide complete nutrition.

Transitioning Foods

When transitioning your 8 week old puppy to a new food, it’s important to phase it in gradually over 4-7 days. Here are some tips for a smooth transition:

  • Slowly mix in increasing amounts of the new food while decreasing the old food
  • Aim for a 25% increase in new food every few days
  • Gradually transition until your puppy is eating 100% new food
  • Watch for signs of digestive upset like vomiting or diarrhea
  • Slow the transition if needed to ease digestion

Changing foods too quickly can disrupt your puppy’s stomach. Take your time to allow their system to adjust to new proteins and fiber sources. If diarrhea develops, go back to feeding more of the previous food until stools firm up.

Monitoring Puppy Growth

To ensure your 8 week old puppy is eating the right amount, pay close attention to their growth and body condition. Here are some things to monitor:

  • Weight: Weigh your puppy weekly and watch for steady gains based on breed standards
  • Body condition: Run hands over ribs to feel a thin layer of fat. Visible ribs could mean underfeeding.
  • Energy: Active, playful puppies are getting adequate nutrition
  • Coat: Shiny coats signify health; dull coats may indicate deficiencies
  • Eyes: Clear, bright eyes are desired over runny, crusty eyes
  • Stool: Firm stools demonstrate good food digestion and nutrient absorption

Record keeping can help identify growth trends over time. Discuss any concerns with your veterinarian and adjust food amounts accordingly. Slow growth may indicate underfeeding, while rapid gains can stress bones and joints.

Potential Problems with 8 Week Old Puppies

Some potential health issues to monitor with 8 week old puppies include:

  • Hypoglycemia: Low blood sugar, more common in small breeds
  • Dehydration: Fail to drink enough water
  • Intestinal parasites: Worms, giardia from unsanitary conditions
  • Vomiting and diarrhea: Dietary indiscretion, food reactions, infections
  • Urinary tract infection: From bacteria in the bladder
  • Upper respiratory infection: Contagious viral infection

Preventative puppy care like deworming and vaccination is important at this age. Seek veterinary care if you notice lethargy, vomiting, diarrhea, or other concerning signs. Providing optimal nutrition helps keep your puppy’s immune system strong.

Puppy Feeding FAQs

Here are answers to some frequently asked questions about feeding 8 week old puppies:

Should I free-feed my 8 week old puppy?

Free-feeding, or leaving food out all day, is not recommended for 8 week old puppies. Scheduled mealtimes make it easier to monitor food intake and potty training. Feeding 2-4 scheduled small meals per day according to your puppy’s needs is best.

How do I transition my 8 week old puppy to scheduled feedings?

Start by establishing consistent mealtimes like 7am, 12pm, 5pm. Remove food between meals. Slowly decrease meal sizes if your puppy is overeating. Increase amounts if they act hungry before the next meal. Keep adjusting based on appetite until your schedule is working.

Should I give my 8 week old puppy water all day?

Yes, fresh water should always be available for your 8 week old puppy. Limiting water can lead to dehydration. Make sure the bowl is cleaned and refilled frequently. Don’t restrict nighttime water unless specifically directed by your veterinarian.

What human foods are safe for an 8 week old puppy?

Avoid feeding table scraps, which can upset your puppy’s stomach. Cooked, lean meats, plain yogurt, or small amounts of fruits/veggies (no grapes or onion) can be occasional treats. But a complete puppy food is recommended as the dietary foundation.

How do I know if my 8 week old puppy is too thin or overweight?

You should be able to feel your puppy’s ribs with a light layer of fat over them. Obvious ribs or a sunken abdomen means underweight. Having no discernible waist when viewed from above may indicate overweight. Check with your vet if you’re unsure.


Feeding an 8 week old puppy a nutritionally complete diet 3-4 times per day is important for their rapid growth and development. Provide the recommended daily amount based on your puppy’s size and breed, dividing it into scheduled meals. Monitor growth and body condition, adjusting food amounts as needed. With proper nutrition and veterinary care, your puppy will be on their way to a healthy start!
