Factors that Affect Pomeranian Growth

Pomeranians are small and adorable canines loved by many, and their size and cuteness are why they are so popular. However, many factors can affect their growth, such as genetics, nutrition, and environment. In this section, we will explore these factors in more detail.


Genetics is one of the most influential factors that affect Pomeranian growth. The parents’ size is a good indicator of how big the puppy will grow, and if the parents are small, the puppy will likely be small as well. However, genetics is not the only factor determining the Pomeranian’s size; other factors such as nutrition, environment, and activity level also play a role.


Nutrition is another critical factor that affects Pomeranian growth. A well-balanced diet high in protein, fats, and other essential nutrients is crucial for their development. Pomeranians need a diet specifically formulated for their breed to ensure they get the right amount of nutrients they need.  Overfeeding, insufficient food, or poor quality food can affect their growth and overall health.


The environment in which the Pomeranian lives can also affect their growth. A clean and safe environment is essential for their growth and development. Pomeranians that live in dirty and unsafe environments are more likely to develop health problems that can affect their growth. 

Additionally, the activity level of the Pomeranian can also affect their development. Pomeranians that are over-exercised may have slower growth rates than those more active. Factors such as genetics, nutrition, and environment can affect Pomeranian growth.

A well-balanced diet, a clean and safe environment, and enough physical activity can help the Pomeranian grow to its full potential. It is essential to monitor their growth and consult with a veterinarian if there are any concerns about their growth rate.

Stages of Pomeranian Growth

Pomeranians are tiny, adorable dogs that have captured the hearts of many. They are known for their fox-like faces, small size, and fluffy coats. Like all dogs, Pomeranians go through different stages of growth and development throughout their lives. In this section, we will explore the various stages of Pomeranian growth.

Puppy Growth

Pomeranian puppies are born weighing only a few ounces. They are tiny and helpless, relying on their mother for everything. Pomeranian pups spend most of their time sleeping and nursing during the first few weeks of life. As each day passes and they grow, they become more active and curious about their surroundings.

There are seven acknowledged Pomeranian puppy growth stages: 

  • Stage one: which is from 0 to 3 weeks. 
  • Stage two: which is from 3 to 7 weeks. 
  • Stage three: which is from 7 to 12 weeks.
  • Stage four: which is from 12 to 17 weeks.
  • Stage five: is from 17 to 40 weeks.
  • Stage six: is from 40 to 52 weeks.
  • Stage seven: which is one year and older.


During adolescence, Pomeranians experience growth spurts and may gain weight quickly. Monitoring their weight and ensuring they are not becoming overweight is essential. Pomeranians may also go through a phase where they lose some puppy fur and grow in their adult coats. Their muscles begin to develop, and they look more like full-grown Pomeranians.

Adult Growth

Pomeranians typically stop growing after 12 months, but some may continue to mature until 18. The majority of their growth occurs during the 0 to 12-month period.  For some Pomeranians, growth may continue into the 18- or 20-month period, but this growth tends to be confined to smaller puppies Poms.

Senior Pomeranian

As Pomeranians enter their senior years, they may begin to lose muscle mass and weight. Their appearance may change, and they may become less active. It is vital to monitor their weight and ensure they are not losing too much weight. Senior Pomeranians may also experience health issues, such as arthritis and dental problems.

Pomeranian growth is a fascinating process that involves different stages of development. Pomeranians undergo many changes, from their tiny puppy to their full-grown adult stage. Monitoring their weight and ensuring they are healthy throughout their lives is essential.
