Mini Goldendoodle is an adorable hybrid dog resulting from the cross between a Toy Poodle and a Golden Retriever. You’ll come across three types of Goldendoodles: standard, medium, and mini. Evidently, the Mini Goldendoodles are the smallest.

An adult Mini Goldendoodle weighs about 15 to 35 pounds and stands 13 to 20 inches tall. The exact weight and size of these dogs vary with different factors, such as genetics, diet, age, and the parent’s size.

This guide will break down the size and weight of a Mini Goldendoodle according to their age, so you can know if your pal is growing healthily. Let’s dive in.

Mini Goldendoodle: Breed Overview

Mini Goldendoodles are affectionate, loving, and social dogs. They prefer being around humans and other pets, making them one of the best family dogs. Their adorable smile and appearance make them everyone’s favorite.

If you have seen Goldendoodles, the Mini Goldendoodles are similar except for the size variation. Unlike other breeds in the Canidae family, Mini Goldendoodles grow slower to adulthood. You may notice an increase of 2 inches in their height every month from birth, but it will slow down beyond 6 months.

Mini Goldendoodles reach their maximum height by 12 to 15 months. Even then, they seem like a cute little ball of fur!

Mini Goldendoodle: Size and Growth Chart

A Mini Goldendoodle’s average weight and size depends on its parents, genetics, and diet. A healthy Mini Goldendoodle can grow about half the height of a Golden Retriever.

Suppose you breed a Golden Retriever measuring 21.5 to 24 inches tall and 55 to 75 pounds heavy with a Toy Poodle. In that case, the resulting Mini Goldendoodle can be anywhere around 16 to 20 inches in height and 25 to 35 pounds in weight.

Remember, a Mini Goldendoodle’s size increases quickly—about 2 inches—until 6 months. After that, it slows to 1 inch until the dog reaches 15 months. Here is a detailed overview of how big a Mini Goldendoodle can get:

Age Weight Range (pounds) Length Range (inches)
Birth–2 weeks 0.5–2 4–6
1 month 1.5–2 7–9
2 months 2–4 8–10
3 months 4–6 10–12
4 months 6–10 12–14
5 months 10–14 12–15
6 months 14–18 13–16
7 months 18–22 13–16
8 months 22–26 13–16
9 months 26–30 13–16
10 months 30–32 14–16
11 months 32–33 14–16
12 months 33–35 15–16
13 months 34–35 16–18
14 months 35–36 16–20

When Does a Mini Goldendoodle Stop Growing?

Keeping a check on your Mini Goldendoodle’s size is important for its optimum health. If you see your pup’s height suddenly stopping, don’t panic. It’s normal for a Mini Goldendoodle’s height to slow down after 6 months.

A newborn Mini Goldendoodle weighs around a pound and measures up to 6 inches. After 2 weeks, their weight doubles up to 2 pounds and their height increases to 9 inches. These dogs grow significantly during 3 to 12 weeks.

A 4- to 6-month-old Mini Goldendoodle typically reaches half of its maximum weight. That’s when their growth spurts end, and you see a considerable decrease in their growth rate. Your pup may also feel less hungry at this age.

The typical height of a Mini Goldendoodle is 16 inches, but it can reach 20 inches depending on its parent’s size. You can expect your pup to stop growing by 6 to 8 months.

Factors Affecting the Size of a Mini Goldendoodle

A Mini Goldendoodle’s size depends on a range of factors. The primary ones include:


The Mini Goldendoodle is a resulting breed of a Golden Retriever and a Toy Poodle. So, their size varies depending on their parent’s height and weight. For instance, an 11-inch Poodle and a 24-inch Golden Retriever’s resulting Goldendoodle can be around 18 to 20 inches tall.


Male Mini Goldendoodles are generally bigger and heavier than females. That’s primarily because they have more fur layers than their opposite gender.


A Mini Goldendoodle lives for 13 to 17 years at maximum. Despite being the smallest Goldendoodles, these dogs are believed to have longer lifespans than all the other types. The other Goldendoodle breeds usually live for 10 to 12 years.

Ideal Diet for Maintaining a Healthy Weight

A dog’s diet is directly related to its size. A well-fed dog is more likely to reach their healthy size in the expected duration than those who don’t get enough nutrition. Remember, every dog is different, so their nutritional needs are also not the same.

When a Mini Goldendoodle is in their puppyhood, they have high energy levels and a big appetite. So, you’d have to provide them with calorie-rich foods full of healthy nutrients. Comparatively, adults or older dogs require fewer daily calories due to reduced activity levels.

To maintain your pup’s healthy weight, you must fulfill its nutritional requirements at every developmental stage. It’s recommended to consult a professional nutritionist to determine the best diet for your Mini Goldendoodle.

Generally, dogs love chicken, lamb, whitefish, rabbit meat, salmon, and beef. These are the best protein sources for your pal. Give fresh, raw, canned meals to meet their daily nutritional needs. You should avoid low-budget or low-quality foods with filler ingredients.

How to Measure Your Mini Goldendoodle

Measuring a Mini Goldendoodle’s height can be challenging if you’re a new parent. So, here is a step-by-step to help you out:

  • First, find a measuring tape that you can easily wrap around your Mini Goldendoodle’s body.
  • Next, put your dog on a flat surface and make them stand naturally. Measure their height by placing the tape on their body from the ground to their shoulders, also called withers.
  • Now, measure your Mini Goldendoodle’s length. Put the tape on their neck’s base and run it along their spine to where their tail ends.
  • Note all the measurements in inches in a notebook.
  • Repeat this process every month and compare the measurements to stay updated about your puppy’s size.

As you know, Mini Goldendoodles typically stand 13 to 20 inches tall. You can compare your pet’s measurements with this standard size range based on their age to assess whether they’re growing healthily.

Remember, all dogs are different, and so is their size and growth pattern. Your Mini Goldendoodle may grow faster or slower than your friend’s dog, so don’t rush to your vet daily. Instead, fulfill your dog’s nutritional requirements, keep them happy, and watch them grow at their own pace.

However, consult an expert if their growth rate falls below the normal range.

A Mini Goldendoodle is a cute, small dog breed that doesn’t grow too apparently. The typical size of this breed ranges between 13 to 20 inches. A newborn measures only 6 inches and weighs a pound.

Typically, the Mini Goldendoodle’s size increases by 2 inches every month till they reach 6 months. After that, their growth rate stops or slows to 0.5 or 1 inch monthly. So, if your Mini Goldendoodle barely grows after 6 months, don’t worry, that’s normal. Not every Mini Goldendoodle has to reach the 20 inches mark.

Just provide your dog with a well-balanced diet full of protein, vitamins, and minerals to ensure their healthy development.
