Goldendoodle Growth Chart: What to Expect Month by Month

Bringing home a Goldendoodle puppy means watching them grow — fast! But just how big will your fluffy friend get? And when will they stop growing?
This Goldendoodle growth chart breaks down what to expect month by month so you can ensure your pup is on track for healthy development.

Understanding Goldendoodle Growth

Goldendoodles are a cross between a Golden Retriever and a Poodle, and their size can vary depending on which parent’s genes they take after. Genetics, diet, and exercise all play key roles in their growth patterns.

Mini, Medium, and Standard Goldendoodle Sizes

• Mini Goldendoodles: 15–30 lbs full grown

• Medium Goldendoodles: 30–50 lbs full grown

• Standard Goldendoodles: 50–90 lbs full grown

Each size follows a similar pattern, just on a different scale.

Goldendoodle Growth by Month

Let’s take a closer look at what happens each stage of your doodle’s development.

---

Month 1–2: Puppy Beginnings

Your Goldendoodle is still adjusting to the world. Expect rapid weight gain, soft coats, and sleepy days. They’re tiny but growing fast!

---

Month 3–4: Fast Growth Stage

This is the “growth spurt” period — you’ll notice your doodle getting longer legs and more energy. Start socialization and introduce light training.

---

Month 5–6: Teenage Transition

They’re becoming curious explorers! Growth starts to slow slightly, but your puppy may gain several pounds each week.

---

Month 7–9: Filling Out

Muscles develop, coats thicken, and they start to look like mini adults. Medium and standard doodles may hit half their adult weight by now.

---

Month 10–12: Approaching Full Size

Your doodle’s height stabilizes, but they’ll continue filling out in weight and muscle.
Mini doodles are usually near full-grown, while standards keep growing.

---

Month 12–18: Final Growth & Maturity

This is where your doodle evens out into their adult body.
You’ll notice calmer behavior and a fully developed personality (well, mostly!).

Factors That Influence Growth

1. Genetics: Parent size and lineage determine much of the growth pattern.

2. Nutrition: High-quality food helps your doodle grow strong and healthy.

3. Exercise: Regular play supports muscle tone and healthy development.

4. Health: Illness or parasites can slow growth — regular vet visits are key.

Feeding and Nutrition Tips

Feed according to your doodle’s size and energy level.

• Choose puppy food rich in protein and omega fatty acids.

• Split meals into 3–4 feedings a day during early months.

• Always provide fresh water.

When to Be Concerned About Growth

If your Goldendoodle isn’t gaining weight or seems too thin, talk to your vet.
Signs of concern include visible ribs, low energy, or a sudden loss of appetite.

Conclusion

Watching your Goldendoodle grow is one of the best parts of puppyhood! With the right nutrition, care, and love, your doodle will reach their full potential — both in size and personality.
