When Is A Boxer Full Grown – Guide

Boxers are a medium to large-sized dog breed. They typically weigh anywhere from 50-70 pounds and stand at 21-25 inches tall at the shoulder. However, there is some variation in size within the breed. 

Some Boxers may be smaller or larger than this range, depending on their parentage and genetics. The average Boxer will reach their full adult size by 18-24 months old. 

However, it is not uncommon for a Boxer to continue to fill out and add muscle mass up until they are 3 years old. 

Factors That Affect The Size Of A Boxer

There are a few factors that can affect the size of your Boxer. Diet, exercise, and genetics all play a role in the final size of your pup. 

1. Diet

What you feed your Boxers will have an impact on their size. A diet that is high in calories and protein will help your Boxer to grow to its full potential. 

Moreover, a good diet will also help to ensure that your Boxer stays healthy and doesn’t experience any problems with their joints or bones as they grow. 

2. Exercise

Exercise is important for all dogs, but it is especially important for growing puppies. A lack of exercise can lead to your Boxer being overweight, which can then impact their joint health and lead to other problems down the road. 

To ensure that your Boxer stays healthy and reaches their full size, make sure to give them plenty of opportunities to run and play. 

A good rule of thumb is to provide your Boxer with at least 30 minutes of exercise per day. 

3. Genetics

The final factor that affects the size of your Boxer is genetics. If you have a large-boned Boxer, they will likely be on the bigger side. 

Conversely, if you have a small-boned Boxer, they will likely be on the smaller side. There is not much that you can do about this factor, but it is something to keep in mind when determining the size of your pup.

It includes dry food, wet food, and raw food. The diet should be based on high-quality proteins, healthy fats, vegetables, and fruits. 

Exercise Routine
