Free Puppy Growth Chart & How to Create Your Own

“How big will my puppy be?” is something you frequently hear if you run a veterinary practice. With a puppy growth chart, pet owners can visualize how their pup will reach adulthood, while veterinarians can ensure that each pet progresses healthily through puppy development.

Monitoring a puppy’s growth helps pet parents calculate the final size of their pup easily. With comprehensive puppy growth charts, your team can ensure that puppies generally hit their target weight categories without any hiccups.

Below, we discuss everything you need to know about creating puppy growth charts for your vet clinic for small, large, and giant dog breeds.

Understanding Puppy Growth Stages

If you look at any growth chart for puppies, you’ll notice that the line generally doesn’t move perfectly straight. Instead, you’ll see a curve, depicting fast growth in the younger months before the puppy’s weight gain slows down.

So, what months do puppies grow the most? Puppies typically experience rapid growth during their first six months before the growth rate begins tapering off.

Only very large and giant breeds will show significant growth after the six-month mark. When evaluating dog weight at 6 months vs. full grown, most medium and smaller breeds have already reached nearly 75% of their fully grown weight at six months, while larger breeds may be at the 50% mark. Most puppies will reach 50% of their body weight at the three- to five-month mark.

To better understand how puppy development occurs, allowing different breeds to reach adult size, let’s look at each puppy growth stage:

Neonatal Stage (0-2 weeks)

The neonatal period spans from birth to two weeks old, when puppies are entirely dependent on their mothers for nutrition and care. During this stage, puppies experience rapid growth and development, gaining body fat daily.

Because of the rapid growth during this stage, neonatal puppies typically nurse up to 10 times a day during their first week. A breeder or veterinarian can look at a puppy’s weight and stool to determine its overall health during these first couple of weeks.

Transitional Stage (2-4 weeks)

The transitional period spans from weeks two to four. At the beginning of this stage, puppies have typically already doubled in size and are now beginning sensory development. At the end of 14 days, puppies’ eyes and ear canals fully open, allowing them to explore their surroundings for active learning.

During the transitional stage, feeding is typically reduced to around four times a day, but puppies can begin weaning from their mothers to try solid foods. The puppy food typically needs to be watered down.

Frequent weigh-ins during the transitional stage are crucial for measuring the puppy’s growth and health. Puppies should be weighed daily using a puppy growth chart during the first four weeks.

Socialization Stage (4-12 weeks)

The socialization period spans from 4 to 12 weeks when senses fully heighten, testicles for males drop, and rapid weight gain occurs. Now that the pup has clearer vision and heightened smell, it begins interacting more with its fellow puppies, learning how to play, socialize, and interact. The chewing stage typically begins around this time as puppies learn how to respond to their environment.

Social interactions are highly important for any dog breeder during this stage, as they can shape the puppy’s personality and attitude toward other people or animals. The socialization stage also prompts the ideal time for puppies to receive their required vaccines. As a veterinary clinic, you should encourage breeders or pet owners to schedule the required vaccines during this time.

Juvenile Stage (3-6 months)

The juvenile period extends from three to six months, as the puppy experiences steady growth and increased activity. This is the stage for bringing home puppies from breeders, which means parents must continue training and socialization activities on their own. At this age, the babies may exhibit many behavioral challenges that require strict training.

Near the end of this stage, the growth plates begin to close for toy-sized and small breeds, and they near sexual maturity. Big dogs will experience the same a couple of months later. As a veterinarian, you may want to discuss spay or neuter options with clients around this time.

Adolescent Stage (6-18 months)

In the adolescent stage, puppies stop growing at the same rate as when they were younger. While the growth may slow down, pet parents still need to keep up with training as the behavioral needs remain challenging.

Most puppies reach their adult weight and size by 6 to 24 months. Small dog breeds reach their full adult size much more quickly than larger dogs.

Factors Affecting Puppy Growth

Lots of factors can affect a puppy’s weight and growth rate, including the following:

Breed and Genetics

A dog’s breed is the main determining factor in the puppy’s adult size, adult weight, and adult height. A German Shepherd will never be the same size as a chihuahua. Different breed sizes also grow at different rates, as small puppies tend to grow faster than giant breeds.

A puppy’s breed can also have genetic predispositions for certain health conditions affecting weight. For example, increased blood pressure, insulin resistance, and dyslipidemia can increase obesity risks.

Nutrition

Nutrition directly impacts a puppy’s growth. All dogs need a balanced diet as they progress through the different developmental stages. Adhering to the recommended feeding schedules associated with each puppy stage can ensure that the pup stays within its target weight according to the puppy growth chart.

For example, neonatal pups often require feeding as many as 10 times a day, while dogs in the transitional stage usually only need to be fed four times a day.

Exercise

Dogs require exercise to stay healthy. Without the appropriate exercise routine, dogs can lack the required muscle for their weight category or can become overweight. Exercise routines can vary by breed size, type, and dog age, but pet parents must avoid over-exercising to prevent injury.

Health and Veterinary Care

Vet visits also impact pup weight. With routine vet check-ups, recommended vaccines, and frequent monitoring of common growth-related issues, dogs can avoid concerns that may stunt their growth. As a vet practice, you should encourage clients to schedule routine visits, checking the current weight of their pup to treat problems early on.

How To Use a Puppy Growth Chart

Puppy growth charts allow pet parents to track their puppy’s weight, while veterinarians can use the data to check for potential health concerns:

Tracking a Puppy’s Weight and Height and Calculating Their Adult Weight

To use a growth chart, pet parents and veterinarians need to understand how to properly measure dogs and use the figures correctly. Here’s how you can track a puppy’s weight or teach your clients to do so:

1. Determine the puppy’s size category: To use any growth chart, you need to know what category the adult dog will fall into once fully matured. Small and toy dogs range from 0 to 20 pounds, medium dogs go up to 50 pounds, large dogs can reach 100 pounds, and giant dogs exceed 100 pounds.
2. Use a digital scale: The best way to weigh a puppy is by using a digital scale for accuracy.
3. Weigh the dog regularly: To measure how a puppy grows, owners should weigh their dog once a week, if possible, or rely on their clinic to do so during check-up visits.
4. Measure results based on the chart: After each weigh-in, use the weight, age, and size category to evaluate the puppy’s health.

Recognizing a Normal Puppy’s Growth vs. Abnormal Patterns

One of the primary applications of a puppy growth chart is understanding growth curves and when to seek veterinary advice. For example, two female dogs of the same age and litter should grow at a similar rate, but if one puppy begins slipping behind, the owner should bring them in for an exam.

Examples of Puppy Growth Charts

If your clients frequently ask, “How can I estimate how big my puppy can get?” Use our example growth charts below to provide estimated final adult weights:

Small Dog Growth Chart and Example

A smaller puppy can reach full maturity with their growth plates closing by six months. At around three months, they may be chasing balls, and by four months, they can typically respond to their name.

Here is an example small dog growth chart:

• 0 weeks: 8 ounces
• 2 weeks: 3 pounds
• 4 weeks: 9 pounds
• 6 weeks: 13 pounds
• 8 weeks: 15 pounds
• 12 weeks: 17 pounds
• 24 weeks: 20 pounds

Growth Chart for Medium Dog Breeds

A medium-sized puppy doesn’t reach its full size until around 12 to 15 months. Such breeds may hit puberty later, at around 9 to 10 months. Here is an example growth chart for medium dogs:

• 0 weeks: 10 ounces
• 2 weeks: 7 pounds
• 4 weeks: 21 pounds
• 6 weeks: 30 pounds
• 8 weeks: 35 pounds
• 12 weeks: 38 pounds
• 24 weeks: 40 to 45 pounds

Dog Weight Chart for Large Breeds

Large females and males may not reach puberty until they’re over a year old, meaning they can continue growing well into the 12 to 15-month range. Here is an example dog weight chart for a large-breed puppy:

• 0 weeks: 1 pound
• 2 weeks: 18 pounds
• 4 weeks: 38 pounds
• 6 weeks: 55 pounds
• 8 weeks: 62 pounds
• 12 weeks: 70 pounds
• 24 weeks: 80 to 85 pounds
