Boxer Growth – What Age Does The Boxer Reach Full Maturity?

One thing you should know about your puppy when you adopt it is its growth rate. For example, if you adopt a Boxer, then you’ll want to have an idea of the Boxer growth stages. Knowing this will help you keep your pup happy and healthy. Also, you’ll have a better idea about how your puppy should be developing.

When Does The Boxer Reach Full Maturity?

Believe it or not, a Boxer reaches sexual maturity before fully maturing physically and mentally.

Between the ages of six and 12 months, your male or female Boxer will be ready to breed.

However, Boxers don’t typically reach maturity until they are between 18 and 24 months old. So once your Boxer is 24 months old, or two years, they’ll be considered an adult. 

How Big Is A Boxer When Fully Grown?

According to the American Kennel Club, male Boxers are typically bigger than females.

So, if you have a male Boxer, you can expect them to be between 23 to 25 inches tall and weigh between 60 and 70 pounds. On the other hand, if you have a female Boxer, you can expect them to grow to be about 21.5 to 23.5 inches tall and weigh between 55 and 65 pounds.

What’s The Boxer Growth Rate?

You’ll be able to tell when your Boxer is fully grown by using a few different methods. First, you can tell by their age when they should be fully grown. Also, you can talk to your vet.

As a puppy, be sure to bring them to the vet often enough to keep them up to date with their vaccinations and boosters. Also, the vet can track their growth and development. You’ll be able to get a good indicator of whether they’re an average size or on the smaller or larger size.

In addition, you can take a look at your dog’s paws. As a puppy, their paws will already be rather large. So you can track how well they grow, fitting into their paws.

Finally, if you got your dog from a breeder, you can ask them about the parents’ growth rates. That should be a good indicator of when your Boxer puppy will be fully grown. It won’t be exact, but you can get a good idea.

Alternatively, you can get a DNA test done on your dog.

Boxer Growth And Development

At birth, newborn Boxer puppies should weigh between 2.5 and 3 pounds. For the first two weeks of their life, they’ll grow quickly. Your Boxer puppy should weigh between 4.5 and 5.5 pounds at two weeks old.

From three weeks to eight weeks old, your Boxer puppy should weigh between six to seven pounds to 17 to 19 pounds.

At about three months old, or from nine weeks to 12 weeks, the Boxer should weigh 25.5 and 28.5 pounds. Then, your Boxer should weigh about 35.5 to 40 pounds at four months.

Finally, you can expect your pup to be about 75% of their fully grown weight at six months. Male Boxers should weigh between 41 to 48 pounds, and female Boxers should weigh 39 to 44 pounds.

At this point, the Boxer growth rate will slow down. Your Boxer will almost be their full weight and full maturity by the time they are about one year old. For example, males should be about 57 to 68 pounds, and females should be about 52 and 61 pounds. 

By the time they are a year and a half to two years old, the Boxer should be their full weight. 

Boxers Are Medium To Large Dogs

Since Boxers are bigger dogs, they take longer to reach their full maturity and full growth. As a result, their growth rate is slower. Thus they’re slower to mature.

Small dog breeds typically reach their full maturity and growth by the time they are one year old. Unfortunately, they’re smaller, so they have less growth overall.

Medium and large-sized dogs take longer to reach their full maturity because they have more body mass to fill out. This is why Boxers can take up to two years to fully mature.

How Big Is Your Boxer?

With proper dieting and regular vet visits, you can easily keep track of your Boxer’s growth rate. Then, without any health complications, your furry friend can grow into a happy and healthy doggo.
