Key Takeaways

  • Mini Goldendoodles typically grow between 13 and 20 inches tall.
  • They can weigh anywhere from 15 to 35 pounds.
  • Factors like genetics, nutrition, and activity level can influence their size.
  • It’s helpful to consider the parentage and consult with a reputable breeder for more accurate predictions about your Mini Goldendoodle’s size.

Factors Affecting the Size of Mini Goldendoodles

Genetics, nutrition, growth spurts and plateaus, neutering and spaying, physical health and activity level can all impact the size of a Mini Goldendoodle.


Genes play a big role in how big a mini Goldendoodle gets. These dogs get their genes from two very different breeds, Golden Retriever and Poodle. Sometimes they take more after the Golden Retriever side, sometimes the Poodle.

This mix can lead to size changes. Some Mini Goldendoodles might be bigger or smaller than others because of this gene mix. Dogs have dominant and non-dominant genes that control their looks and size, similar to hair color in people! Every dog’s genetic makeup is unique.


Proper nutrition plays a crucial role in determining the size of a Mini Goldendoodle. Feeding your dog a balanced diet that is appropriate for their age, size, and activity level can help support healthy growth.

Make sure to provide high-quality dog food that contains essential nutrients like protein, vitamins, and minerals. Avoid overfeeding as excess weight gain can impact their size. Keep in mind that each dog is unique and may have different dietary needs, so consulting with a veterinarian is recommended to ensure your Mini Goldendoodle gets the right nutrition for optimal growth.

Growth spurts and plateaus

During a Mini Goldendoodle’s growth, they may experience periods of rapid growth called “growth spurts,” as well as times when their growth slows down or plateaus. These growth spurts and plateaus are natural and can vary from dog to dog.

It’s important to provide your Mini Goldendoodle with proper nutrition during these phases to support their development. Additionally, regular exercise and playtime help keep them healthy and active.

Monitoring their weight and consulting with your veterinarian will ensure that your Mini Goldendoodle is growing at a steady pace and reaching their appropriate size.

Neutering and spaying

Neutering and spaying can also affect the size of a Mini Goldendoodle. When dogs are neutered or spayed, their hormone levels change, which can impact their growth. In some cases, dogs that are neutered or spayed at an early age may not grow as large as those who are left intact.

However, it’s important to note that this is just one factor among many that influence a dog’s size. Other factors such as genetics and nutrition play a significant role in determining how big a Mini Goldendoodle will get.

Physical health and activity level

Mini Goldendoodles require regular physical activity to maintain their overall health and well-being. Regular exercise, such as daily walks or playtime in a fenced yard, helps keep them fit and prevents weight gain.

It is important to provide mental stimulation as well through interactive toys and training sessions. Keeping your Mini Goldendoodle at a healthy weight can help prevent joint issues and other health problems as they age.

Regular vet check-ups are also essential for monitoring their physical health and addressing any concerns early on.

Consider parentage

When determining the size of a Mini Goldendoodle, it’s important to consider their parentage. The size of the parents can give you a good idea of how big your Mini Goldendoodle might get.

If both parents are on the smaller side, then your dog is likely to be smaller as well. However, if one or both parents are larger in size, then your Mini Goldendoodle may end up being bigger.

Keep in mind that there can still be some variation within litters, so it’s not a guarantee. Consulting with a reputable breeder who has experience breeding Mini Goldendoodles can also help you get an idea of what size to expect based on their knowledge and previous litters they have produced.

By consulting with a reputable breeder, you can make a more informed decision about bringing home a Mini Goldendoodle that suits your preferences and lifestyle.


In conclusion, the size of a mini Goldendoodle can vary depending on factors like genetics, nutrition, and activity level. On average, they stand between 13 and 20 inches tall at the shoulder and weigh around 15 to 35 pounds.
