But First, Pin It!

In this article, you’ll learn about growth patterns for each type of Doodle. You’ll also find our interactive Doodle puppy growth chart and calculator, which will predict how much your Doodle will weigh at full-grown!

Now, you’ve probably heard that it’s pretty much impossible to predict exactly how each individual Doodle puppy will grow. It’s true – because Doodles are hybrids, each Doodle’s genes will dictate how large or small it will be when full-grown.

This unpredictability might be leaving you feeling worried, anxious, or simply just curious. Luckily, we can take a “guesstimate” on your pup’s final adult weight based on observed growth patterns.

Puppy Growth Chart Patterns

Like most dog breeds, Doodles do their fastest growing in the first 50% of their adult weight, which generally correlates to the first six months of life. They generally reach their maximum height by one year old but can spend a little longer gaining girth and weight. They generally finish growing anywhere between 1-2 years of age.

Our Doodle puppy growth chart calculator references data from this study. Let’s explain the data according to dog size.

Toy Doodles

In the study, “small” dogs weighed between 5-15 lbs. This weight range is typically associated with Toy Doodles.

Based on the study’s data averages, we estimate that Toy Doodles generally reach half their adult weight at approximately 3.5 months old. A Toy Doodle will then plateau at its full adult weight between 7.5-11 months of age.

If you want to do a quick calculation, here’s the formula you would use to estimate the adult weight for a Toy Doodle:

Toy Doodle Weight Prediction Formula:

Adult Weight = Weight at 15 weeks old x 2

Example: My Toy Aussiedoodle’s weight at 15 weeks is 7 pounds. Times 7 by 2 and I get 14 pounds as his predicted full-grown adult weight.

Mini/Medium Doodles

In the study, “medium” dogs weighed between 15-55 lbs. This weight range is typically associated with both Mini and Medium Doodles.

Based on the study’s data averages, we estimate that Mini/Medium Doodles generally reach half their adult weight between 3.5 and 5 months old. A Mini/Medium Doodle will then plateau at its full adult weight between 11-13 months of age.

If you want to do a quick calculation, here’s the formula you would use to estimate the adult weight for a Mini/Medium Doodle:

Mini/Medium Doodle Weight Prediction Formula:

Adult Weight = Weight at 18 weeks old x 2

Example: My Medium Goldendoodle’s weight at 18 weeks is 25 pounds. Times 25 by 2 and I get 50 pounds as his predicted full-grown adult weight.

Standard Doodles

In the study, “large” dogs weighed between 55-85 lbs. This weight range is typically associated with Standard size Doodles.

Based on the study’s data averages, we estimate that Standard Doodles generally reach half their adult weight between 4.5 and 6 months old. A Standard Doodle will then plateau at its full adult weight between 12.5-16 months of age.

Note: Since Standard Saint Berdoodles become much larger than 85 lbs., they reach half their adult weight later. More on Saint Berdoodles later.

If you want to do a quick calculation, here’s the formula you would use to estimate the adult weight for a Standard Doodle:

Standard Doodle Weight Prediction Formula:

Adult Weight = Weight at 23 weeks old x 2

Example: My Standard Labradoodle’s weight at 23 weeks is 35 pounds. Times 35 by 2 and I get 70 pounds as his predicted full-grown adult weight.
