Pomeranian Growth Chart – What To Expect

Pomeranian Puppy Development

Birth – 2 Weeks

Pomeranian birth weights can vary from 2.5 oz to 5.5 oz. The first step is to know the starting weight and track from there.

The expected weight gain from birth to 2 weeks is also dependent on the birth weight—however, the expected growth is typically a 140% to 145% increase from the birth weight after 2 weeks—certainly a fast pace!

Therefore, if your Pom was born 2.5 oz, expected weight after 2 weeks would be 6 oz.

3 Weeks – 12 Weeks 

Pomeranian Weight Chart

The 3-week to 12-week period is a crucial stage in the Pom’s development. It is during this period that genetically larger Pom’s will gain a significant amount of weight, far exceeding genetically smaller Pom’s.

For example, a Pom born at 5.5 oz would be expected gain 27.5 oz during this period (17.5 oz at 3 weeks to 45 oz at 12 weeks), while smaller Pom’s can be expected to only reach a 12-week weight of 16 oz.

4 Months – 9 Months

During the 4-month to 9-month period, the Pom would be expected to have grown around 80% to 85% of its total body weight. It is this stage wear the puppy starts to resemble a fully grown Pomeranian.

Depending on the birth weight, the weights of Pomeranian’s after 9 months can vary from 27 oz to 80 oz. Remember, always track from the birth weight of your Pom so that you have an accurate picture of your Pom’s overall health.
