How big will your puppy get?

With the help of our puppy weight estimator, determine your furry friend's adult size. You may estimate your puppy's mature weight and see how big it will develop by entering its age and weight at this time. Use our puppy growth calculator immediately to get precise statistics and discover more about your puppy's development.

How large will my dog get?

Attaining mature weight is a crucial aspect in the development of puppies, especially as the breed size varies. While small dogs generally reach their total growth by 10 months, large breeds continue growing until they turn 18. As a pet owner, it's essential to understand the significance of feeding your furry friend a well-balanced diet with all essential nutrients for optimal growth and weight gain.
If you're concerned about your puppy's weight gain journey, don't hesitate to contact a trusted veterinarian for personalised advice. With their expert guidance and a nutritionally sound diet, you can help ensure your furry companion reaches its full potential and stays healthy.

How can I gauge my puppy's mature size?

Get an accurate estimate of your puppy's adult weight with this handy puppy weight calculator. Simply input your puppy's current weight and age in weeks, and our formula will estimate its adult weight. You can also use these general guidelines for a rough estimate:
  • A newborn puppy's birth weight will typically double in the first week.
  • From there, expect a cumulative 5-10% increase in weight per day.
  • By 6 weeks old, smaller breeds will gain approximately 5 oz. per week while larger breeds will gain around 2 lb 5 oz.
  • To use the formula: (Current Weight / Age in Weeks) * 52 = Adult Weight Estimate.
    • Note that this is just an estimate, and your puppy's final weight may vary depending on various factors such as breed, nutrition, and genetics. Use this as a starting point to monitor your puppy's growth and ensure they are on track to reach a healthy weight as an adult.

    Small dog breeds

    Miniature and toy breed puppies see their mature weight for the first time at six weeks. Simply double their six-week weight by 2, then by 2, and so forth. At six weeks old, a one-pound puppy will grow to about four pounds.

    Breeds of medium- and large-sized dogs

    You'll have to wait a little longer for these fellas because you're basing your expectation on the fact that they're 14 weeks old. The maths is also more complex. Multiply the puppy's age in weeks by 0.5, then add 50% to its weight at 14 weeks.
    A puppy that weighs 20 pounds at 8 weeks will be 40 pounds at 14 weeks, while a puppy that weighs 20 pounds at 10 weeks will be 50 pounds at 10 weeks.
    Another significant weight loss milestone for many men is the six-month mark. At this point, the puppy should weigh roughly two-thirds of his eventual adult body weight. On the other side, giant breed puppies weigh just around half of what they will as adults.

    When will my puppy stop growing?

    It stands to reason that larger dog breeds would take longer to reach adulthood. So, initially, you need to establish whether your dog is a toy, small, medium, large, or gigantic breed. Adulthood can be reached in as little as six months for a toy breed of dog, while a giant breed can take between 18 and 24 months.

    How do I use the dog weight calculator?

    Our puppy development calculator is the most straightforward tool of its kind. Include the dog's age and weight in the appropriate fields. It's essential to pick out a dog's breed as well.
    The dog weight estimator will use the data you've provided to predict how much your dog will weigh as an adult. Your results will also be presented as a range to account for various factors affecting your dog's development and eventual size.

    How can I predict how large my dog will get?

    You can quickly and simply determine how large your puppy will get with the help of our puppy weight calculator. This dog weight calculator was made to help you keep your new pet healthy and happy for many years.

    How large will my dog become?
