Pomeranian Growth Chart

Overview

If you’re the owner of a Pom puppy, you may be wondering how much your Pomeranian will weigh as an adult. Or, if you are thinking of getting a Pom, you may be curious about expected growth. This breed can actually be notably larger than the breed standard guidelines, so estimating a Pom puppy’s growth requires several different formulas. 

This article will cover the Pomeranian growth phase (both duration and rate), breed standard weight vs. the actual adult weight of Poms, the reliability of growth charts, general formulas, and our own growth charts and formulas. 

So, let’s dive in. 

The Pomeranian Growth Phase

Duration

Like many dogs in the toy breed group, the Pomeranian, generally speaking, does most of their growing in the first year. In fact, many are at their final adult size by the 10-month mark, though a good number will still fill out just a bit until the 12-month mark. In a way this makes sense since Poms are also declared to be adults at the age of 1 year old. 

Typically, Pomeranians that are genetically predetermined to be on the small side (3 to 6 or 7 lbs.) finish growing sooner than Pomeranians that are genetically predetermined to be on the large side (closer to 10 lbs. or more). For Poms that are much larger, (15+ lbs. and may be partial or full throwbacks), they may grow until the 15 to 18-month mark. 

Rate

The rate at which Pomeranians grow is never linear; meaning that Poms do not grow bigger by the same amount each day, week, or month. Rather, growth rate is extremely fast during the first few days (with gains made every single day), fairly rapid during the first few weeks, and then it slows down and can become rather staggered with both slow growth and quick growth spurts. 

Breed Standard vs. Actual Weight – An Important Factor with Pomeranian Growth Charts

Before we start looking at some estimates, it’s vital to have a clear and accurate understanding of how big a Pomeranian will be once they are done growing. And this is actually not something you can know by looking at the AKC’s breed standard. 

This is because the breed standard calls out for a Pomeranian to be: “from 3 to 7 pounds with the ideal weight for show specimens being 4 to 6 pounds.” And it is true that just about all Poms that compete in conformation shows fall within this range. 

However, in reality, pet Poms can be larger than this. In fact, a very interesting study that PetPom conducted showed that only 32% of adult Pomeranians were between 3 and 7 lbs. and 69% were between 7.5 and 10.5 or more lbs. Note that the full survey results can be found in PetPom’s GIANT Book of Pomeranian Care.

So, as opposed to calculators or charts that are designed for ending weights to be 3 to 7 lbs., accurate growth charts for Pomeranians must take into account that while some Poms will certainly be small, others will be a rather sturdy size of close to or over 10 lbs.  

How Reliable are Growth Charts?

It’s important to remember that growth charts are mere estimates. At the time that you’re looking at any certain chart, your Pom puppy may be having a slow-down or may be in the middle of a growth spurt and this can throw off the final estimate. 

In many instances, oversized young puppies will grow up to be larger-than-usual adult dogs and undersized pups will be adults on the small side; however, there are always exceptions. And, even if two Pomeranians are at the same age and weight, they may finish at different places. For example, you can have two 8-week-old pups that are both 1.5 lbs. but by the time they are 11 months old, one is a final 5 lbs. and the other is a final 9 lbs. 

So, these are things to keep in mind as we take a look at some formulas to calculate a Pomeranian’s growth as well as a couple of charts. 

General Canine Growth Estimate Formulas

There are a couple of general formulas that are used to calculate a dog’s final size; though whoever created these intended them to be for dogs of all breeds and sizes and for that reason they can easily be off by several pounds (or more, in the case of large breeds). Please note that numbers can be converted to metric at the end.  

Formula #1: Weight at 2 weeks old times 3, then plus 1 pound. For example, for a 2-month old Pom puppy that is 1.5 lbs., the equation would be: (1.5 x 3) + 1 = 5.5. 

Formula #2: Weight at 3 months old times 2. For example, for a 3-month old Pom puppy that is 3 lbs., the equation would be: 3 x 2 = 6. 

PetPom’s Pomeranian Growth Charts

We’ve been fortunate enough to follow and track the weight of lots of growing Pomeranian puppies over the years and these figures have finally culminated into our own growth charts that are fairly accurate, generally within a pound or two. Though, do please keep in mind everything that’s been covered so far in regard to these being estimates only. 
Growth Chart A: Adult Weight Based on 2-Month Weight
Estimating a Pomeranian’s full adult size based on their weight at the 2-month mark is done with a formula in which the weight is multiplied by 3 and then a number ranging from .5 to 1.25 is added on. For the larger sized pups 2.5 lbs. and over, the weight is multiplied by 4. Since this is such a young age with an unknown number of significant growth spurts ahead, final estimates are + or - 2 lbs.

Please note that all weights are in pounds and rounded off to the nearest .25 lbs.

Growth Chart B: Adult Weight Based on 4-Month Weight
Estimating a Pomeranian’s full adult size based on their weight at the 4-month mark is usually more accurate than doing so at a younger age since the most significant growth spurts are complete. The formula for the two smallest weights, 1.25 and 1.5 lbs., is weight x 2.5. For the weights of 2 through 4 lbs., the formula is weight times 2. And for the weights of 4.5 to 5+ lbs., the formula is weight times 2 plus 1. 

Please note that all weights are in pounds and rounded off to the nearest .25 lbs.
