Goldendoodle puppy growth chart: week by week and month by month

Why growth charts matter for Goldendoodles

Goldendoodles are a cross between a Golden Retriever and a Poodle, which means their growth timeline and adult size depend on what generation they are and which parent they lean toward. An F1 (50 percent each) will often grow larger than an F1B (75 percent Poodle), even within the same litter. Charts give you a range rather than a single target, and the range is what matters for setting realistic expectations.

The charts below are organized by size class (Mini, Medium, Standard) because that classification predicts adult size more reliably than generation alone. Check with your breeder to confirm your puppy's classified size class if you are unsure.

Mini Goldendoodle growth chart

Mini Goldendoodles have a Miniature Poodle parent. Adult weight typically falls between 15 and 35 lbs. They grow fastest in the first four months and slow noticeably after six months.

Medium Goldendoodle growth chart

Medium Goldendoodles typically have a Moyen Poodle or a smaller Standard Poodle parent. Adult weight falls between 36 and 50 lbs. This is the most variable size class because the parent size combinations that produce it are wider. Mango is a Medium Goldendoodle.

Standard Goldendoodle growth chart

Standard Goldendoodles have a Standard Poodle parent. Adult weight typically falls between 51 and 90 lbs, with males frequently landing above 65 lbs. They take the longest to finish growing and some large Standards continue filling out past 18 months.

How to predict adult size from puppy weight

The most practical estimator for a Standard Goldendoodle is to double the puppy's weight at exactly 4 months of age. It is not a guarantee but it is accurate within about 10 percent for most dogs.

For Mini Goldendoodles, the formula shifts: use the weight at 5 months instead of 4 months, and double that. Mini Goldendoodles grow more slowly relative to their final size, so the 4-month window underestimates.

Parent weight is the second best predictor. Ask your breeder for the weights of both the dam and sire. Goldendoodle adult size tracks parent size closely, especially when both parents are on the smaller or larger end of their breed standard. If your puppy is an F1B (75 percent Poodle), the Poodle parent's weight carries more influence than the Golden Retriever parent.

When Goldendoodles stop growing in height versus weight

Height growth and weight growth follow different timelines. Dogs reach close to their adult height first, then continue filling out in muscle and frame mass for months afterward.

Mini Goldendoodles typically stop gaining height between 7 and 10 months. Weight growth continues a few more months, usually finishing by 11 to 13 months.

Medium Goldendoodles stop gaining height around 11 to 13 months and reach adult weight by 12 to 15 months.

Standard Goldendoodles continue both height and weight growth through 12 to 18 months. Some large males continue gaining body mass past 18 months, though the rate slows dramatically after the first year.

Growth plate closure by size class

Growth plates are soft cartilage areas near the ends of long bones where new bone tissue is added. They harden and close as the dog matures. Before closure, growth plates are vulnerable to injury. High-impact exercise (running on hard surfaces, jumping from height, repetitive fetch on concrete) before the plates close increases the risk of lasting joint damage.

Mango's actual growth timeline

Mango is an F1B Teddy Bear Goldendoodle, which means he is 75 percent Poodle and 25 percent Golden Retriever. He is in the Medium size class at 45 lbs.

At 8 weeks he weighed 8 lbs, which put him at the low end of the Medium range for that age. At 4 months he was 22 lbs. Doubling that gave a projected adult weight of 44 lbs. At 12 months he weighed 42 lbs. He added a final 3 lbs over the next two months, reaching his adult weight of 45 lbs by 14 months and holding steady there ever since.

His height stopped changing noticeably around 12 months. The weight gain from 12 to 14 months was all muscle and frame fill, not height. That two-month window of slow weight gain after height stops is typical for Medium Goldendoodles.

Growth patterns that warrant a vet check

Growth variation within the chart ranges is normal and does not need investigation. These are the patterns that cross into territory worth checking:

• Consistently below range for three or more checkpoints in a row. One dip is normal. Three consecutive weigh-ins below the low end of the range, especially combined with reduced energy or a dull coat, is worth a vet conversation.
• Sudden plateau followed by a rapid jump. Growth happens in bursts but a complete stop in weight gain for four or more weeks followed by a sudden large gain can signal a hormonal or nutritional issue.
• Visible rib exposure at any age past 12 weeks. Some ribbing is normal in fast-growing puppies at 8 to 10 weeks. After 12 weeks, if ribs are visible rather than just feelable, the puppy may not be taking in enough calories.
• Asymmetric growth. If one leg appears noticeably thicker or longer than the matching leg, or if the puppy is favoring one side, that is a structural concern to address quickly.
• No weight gain after 8 weeks on the same food. If a puppy has been on the same food for eight or more weeks and shows no weight gain while the rest of the litter gains, that is a signal to switch foods or check for a parasite load.

Frequently asked questions

How much will my Goldendoodle weigh as an adult?

Adult weight depends on size class. Minis finish between 15 and 35 lbs. Mediums finish between 36 and 50 lbs. Standards finish between 51 and 90 lbs. The 4-month doubling formula gives a quick rough estimate for Standards. For Minis use the 5-month weight and double that. Parent weights are the most reliable long-term predictor.

When do Goldendoodles stop growing?

Height stops first, weight follows. Minis stop gaining height around 7 to 10 months and reach adult weight by 11 to 13 months. Mediums finish height around 11 to 13 months and weight by 12 to 15 months. Standards continue growing through 12 to 18 months, with large males sometimes filling out past 18 months.

How do I predict the adult size of my Goldendoodle puppy?

Double the weight at 4 months for a Standard. Double the weight at 5 months for a Mini. Ask your breeder for parent weights as a second data point. If your puppy is F1B, the Poodle parent's size carries more weight in the prediction than the Golden Retriever parent.

Is my Goldendoodle underweight?

Compare the current weight to the range in the chart for the puppy's age and size class. A single reading below range is not a concern. Three or more consecutive readings below range combined with visible ribs, low energy, or a dull coat is worth a vet visit. Temporary dips during growth spurts are common and self-correct.

Where can I find a growth chart for Goldendoodle puppies?

The tables above cover Mini, Medium, and Standard Goldendoodles from 8 weeks to 18 months. Ranges account for normal variation across generations and sexes. Males typically run 10 to 15 percent heavier than females within the same size class at any given age.
