Beagle Growth Chart from Puppy to Adulthood: a complete guide

Beagles are small scent hounds, hunting hare dogs, detection dogs, and bright and intelligent dogs. With all these qualities comes a great sense of responsibility in their growing stage from puppy to adulthood. Epilepsy, hypothyroidism, dwarfism, and other diseases are common in Beagles. Raising a dog is similar to raising a human child; if you provide adequate care during their development, you will have less to worry about them developing health problems!

But how long is their growing phase? And at what point does your beagle puppy turns into an adult dog?

This article will give you a complete guide on your beagle’s growth.

Growth Chart for the Beagle: Size, Weight, and Height

As we all know, weight can say a lot about health. Measuring the weight and height of your beagle puppy is the best way of telling if they are healthy or not! As this breed is prone to dwarfism, keeping an eye on your pup’s height is the best precaution you can take!

I guess we all have a weighing machine at our home; that’s all you need to save your trips to the vet every week or month.

Don’t get scared if your pup doesn’t fit precisely in this category because no one’s perfect!   Your pup should fall within these parameters.

Apart from this, if you can see your pup’s ribs, you have an underweight puppy; if you cannot feel his ribs while picking him up, your dog is very likely to be overweight.

Veterinarians aren’t dietitians. They don’t always give the best recommendations for what to eat. You should research a high-quality puppy formula kibble. Your dog will obtain all the nutrition he requires this way, as he must eat a well-balanced diet. 

Puppies require vitamins and minerals that aren’t always included in human food. Pancreatitis can develop if the dog gains too much weight. Try to locate a “fresh” dog food blend that comes in a roll.

How much bigger will my beagle become?

How much bigger will my beagle become?

The most prominent feature of any beagle is its short legs and floppy ears, and they are more diminutive in appearance than the rest of the dogs! As a result, determining when they will stop growing can be tricky.

However, if we talk in numbers, a full-grown Beagle would stand about 13 to 16 inches tall and weigh between 22 and 28 pounds, with males on the heavier side. These dogs are known as mid-sized dogs, not small dogs.

Once your beagle gets to the age of 8 months – 12 months of age, he’s physically and mentally grown! It is unlikely or near to impossible for your dog’s height to grow any further because the growth plates in his bones have closed up.

There are two different sizes for the beagle:

  1. 13 inches: weighs between 22 and 30 pounds and never grows taller than 13 inches.
  2. 15 inches in either 14 inches or 15 inches tall and weighs approximately 35 pounds.

So we are done talking about your pure breed beagle; now it’s time to have a look at the mixed-breed beagles! 

  • Meagal (Beagle + Miniature Pinscher)

Height:12- 16 inches

Weight: 10-25 pounds

  • Malteagle (Beagle + Maltese)

Height: 12 inches

Weight: 15-22 pounds

  • Raggle (Beagle + Rat Terrier)

Height: 16-22 inch

Weight: 40- 55 pounds

  • Bookie (Beagle + Yorkie)

Height: 12-15

Weight: 20-25

  • Beagleman (Beagle + Doberman Pinscher)

Height: 16-22 inches

Weight: 40- 55 pounds 

So here’s a list of mixed breed beagles and their height and weight! At roughly 8 months, beagle breeders can identify if they will stay under 13 inches or not. So it’s necessary to buy a pup from a trusted breeder as they have a piece of complete knowledge about the litter.

Is the Beagle a fast-growing breed?

The answer to this question is a bit complicated, but we will make it easy for you! Foremost, yes, beagles grow faster than other dogs!

 But also, they are a medium-sized breed, so comparing their growth with a large-sized breed won’t be appropriate! The larger the breed is, the longer it will take to grow! So we hope that now you understand why beagles, a medium-sized beagle, grow quickly!

Your beagle will be full-grown before his first birthday!

If the beagle is small, his pups will be on the lower end of the weight spectrum; if the parents are tall, they are likely to be around 20 pounds! After your beagle is 6 months older, his growth will slow down and stop when he is 8-12 months older!

What is the size of a 6-month-old Beagle?

What is the size of a 6-month-old Beagle?

When your beagle is about 6 months old, he will gain 50% of his body weight! 

This means their weight should be between 10 and 15 pounds and 10- 13 inches tall! It is said that until the age of six months, beagles grow faster and as much as they can; once they pass this age, the growth gradually slows down.

At the age of six months, your beagle puppy will no longer be a puppy! 

Why? Because puppy food has a lot of calories and since your pup’s growth will slow down, there is a considerable risk of gaining weight! It’s the right time to switch from puppy food to dog food!

Switching to dog food will provide him with fewer calories and more protein.

So it’s very crucial to take care of your beagle in this stage as it will determine the overall growth in the future.

What is the age at which a Beagle is fully developed?

A beagle is fully grown when it reaches the age of 8 – 18 months. 

This is for most beagles, but you should wait at least for him to be a year old; after that, it’s significantly less likely for them to grow in height; you can’t say the same about weight as they are; very prone to obesity! 

If proper care of their diet and exercise is not taken, they will fall victim to obesity.

It’s also observed that your over-excited beagle will also calm down a bit after he’s fully grown! Consequently, beagles are very hyper at the age of 12- 24 months of age, and they need a lot of exercise and activity for their mental and physical stimulation to stay healthy and happy.

An excellent indicator to know if your pup is still growing, have a look at his paws; they will be prominent in comparison to his body and legs.

Approximately what is the size of a fully grown Beagle?

The American Kennel Club’s Official Standard for the Beagle breed stats:

“ That a grown-up Beagle remaining at 13 inches or fewer ought to weigh under 20 pounds, while a grown-up Beagle is remaining at 13 to 15 inches tall ought to weigh somewhere in the range of 20 and 30 pounds.”

Beagle: Health & Care

Bring your dog to regular check-ups get him vaccinated. Beagles are inclined to hereditary medical problems like plate infection, hip dysplasia, epilepsy, and eye issues.

 Regular visits to your veterinarian can help identify and possibly treat these issues before they get worse.

 A healthy but limited diet, and low-carb, high-nutrient dog food can quickly put on weight. Last but not least, proper care and regular exercise will keep them mentally and physically healthy.

Apart from this, you should take care of the following things:


As a rule, Beagles need 674-922 calories per day. Depending on how active they are, you can adjust their intake. You can go for home-cooked, wet or dry food only after getting hold of the daily calories they require. 

  • Food: Portion/meal
  • Protein : 30% to 40%
  • Healthy Fats: 15% to 20%
  • Carbs: 30% to 50%

Basic commands

Four essentials should be taught to every dog: how to shake hands, what yes and no mean, and proper litter training. They might look fundamental, but help a lot in keeping your dog disciplined.


A clean dog is a healthy dog; make sure you fulfill all the grooming needs of your dog:

  1. Bath
  2. Cleaning his ears 
  3. Cleaning his paws 
  4. Brushing his teeth
  5. Clipping nails

These dogs’ most rapid growth phase would be until they are six months old. After that, the growing phase slows down! As mentioned above, the healthy weight of a beagle pup is less than a pound, and they tend to gain weight every day; that’s the sign of healthiness in beagles.

However, according to the American Kennel Club’s Official Standard:

  • An adult Beagle standing 13 inches or fewer should weigh less than 20 pounds, 
  • While an adult Beagle standing at 13 to 15 inches tall should weigh between 20 and 30 pounds.
  • If we go by gender, the female beagle should weigh around 19.8 to 22 pounds and male 22-24 pounds.

Just like the BMI works for us, it’s essential to consider the height and weight of your beagle as an indicator of their health.

For a Beagle, what is overweight?

We all know that this breed is prone to choking very quickly; no matter how cute they might look with all the surrounding fatness, it’s not healthy! And a beagle owner should take care of such things from a very early age!

Did you know an overweight Beagle lives two years shorter than an average-weight Beagle? Additionally, they are less likely to die naturally due to health issues such as cancer, diabetes mellitus, heart disease, and hypertension.

Is your beagle overweight? Let’s find out how!

There are a few easy ways to tell if you have an overweight beagle: 


Beagles are known for their plump and short appearance, but they can also have a slimmer and athletic appearance, and if you can’t see your Beagle’s ribs while pressing them against his chest, he’s overweight.

Also, here’s how an overweight Beagle looks:

An internal twist between the ribs and the rib enclosure should be apparent from a higher place.

The mid-region should have a slight yet noticeable up-bend to meet the rib confine when seen from the side.

Feel their tail and spine: You should be able to feel their tail and spine base.

Feel the ribs: Do your Beagle’s ribs appear to be well-defined? If you can’t feel your dog’s ribs, they are most likely obese.

It’s easy to tell between a chubby and a slim beagle.

Check your beagle’s ribs:

Observing your dog’s appearance is the most effective technique to determine whether they are becoming too thick. 

A Beagle with exposed ribs is deemed emaciated or underweight! On the other hand, if you can’t feel your Beagle’s ribs when pressing on its chest, it’s overweight or obese.

The same can be said of their spine. On the other hand, a fit Beagle has a waistline that is somewhat smaller than its chest and a thin layer of fat on its tail.

Does your beagle get tired quickly?

Beagles are known for being lively and playful, but if your dog isn’t as active as you’d like, it could be a cause for concern. When a Beagle fails to perform, a daily exercise of 45-50 minutes is required.

Laziness and exhaustion might be aided by a poor diet and a lack of sufficient nourishment. 

To release their energy, this breed requires a lot of running, walking, and a lot of fun. These are all symptoms that your Beagle has put on weight.

Is your beagle flexible enough?

Is your beagle flexible enough?

Your Beagle’s flexibility heavily influences the health and enjoyment quote.

Play some stretching activities with your dog to test its flexibility. It does not necessitate the use of any toys or equipment.

You will gain a better understanding of your dog’s flexibility after playing a few stretching games with it.

Dogs and cats are also excellent groomers, spending half of their time grooming themselves. 

So if your beagle appears to be dirty, then you should know that he’s not grooming himself well because they can’t reach their tail other portions of the body With their tongue due to less flexibility!

An unfit dog will appear dirty.

Is my Beagle so small?

We have discussed so much about the ideal and overweight of the beagle that we almost forgot to think about the opposite of it! Though it might seem quite rare, beagles can be more miniature than they should, and it’s not at all a regular thing, indicating many health issues.

Usually, beagles stop growing by the age of 18 months old, but do you think that your beagle appears to be smaller than other beagles or just something that looks off?

You should follow the growth chart we mentioned above to keep a close eye on your beagle pups’ growth; always keep in mind that it’s unnecessary to get the exact figures. However, if your pup is lacking behind a lot, then it’s a cause for concern!

Here are a few things responsible for your beagle being small: 

  • Chondrodystrophy (beagle Dwarfism)

The beagle Dwarfism has less to do with your current pup than his parents’ medical history! As it’s a genetic disorder. 

On the other hand, there are also a few chances for your beagle to develop this disorder, so both nature and nurture can play a significant role in developing this disorder. 

We need to warn you because this is a slow poison, as the symptoms might take a year or so to show up with the symptoms. Due to their short legs, beagles are prone to develop bone deformities. 

It’s essential to buy a puppy from a licensed breeder because they know every bit of the puppy.

Let’s have a look at the symptoms of dwarfism in beagles:

  • Enormous head but a tiny body 
  • Crooked legs
  • A bent front leg with elbows pointing outward.
  • Larger and more protruding joints.
  • Short jaw
  • Crooked teeth
  • Poor growth 
  • The curvature of the spine to the left or right.

Sometimes, these symptoms take a year to show up or even three weeks after birth, so take your dog to the vet if you suspect any of these.

  • Intestinal parasites

 Roundworms and tapeworms are the most common parasites your beagles could get. 

Tapeworms are frequently contrasted and grains of short-grain rice in their appearance. 

Assuming you see what might seem like rice grains, you will see worms. If at all you end up seeing these worms in your canine’s crap, without anything to do, call your vet for a dewormer.

However, tapeworms’ eggs are noticeable to the unaided eyes.

They will steal and eat up all the nutrition from your dog, making them skinny and weak!

  • Small breeding

Beagles are known for their short height; what if we told you that there is a smaller beagle breed than the usual one?

 The originals were small enough to fit comfortably inside a heavy leather hunting glove, but were eventually replaced by today’s 13- and 15-inch Beagles.

7 to 12 inches of height and 7 to 15 pounds of weight is the average size of this beagle, so if your dog is a small breeding dog, it will be smaller than the usual beagle!

Also, if your beagle’s parents were small in height, there are 90% chances they will pass this on to their offspring.

  • Mix breeding

We all know what mix breeding is; some of you must know people who do it! Mix breeding a dog is not just a crime but also an activity against nature’s will, and that’s why the by-products of such acts are either weak, minor, or sick. You should always ask for the paperwork to prove the originality of a particular breed. 


The beagle primarily developed for hunting hare is now ruling the world by being one of the top and most desirable breeds to adopt. They are not like other dogs, so don’t try to fit them in. Raising them right is not a cakewalk! 

When you adopt a beagle, make sure to keep a close track of him till he’s 8 months older; that’s the crucial phase and requires a lot of care.

However, if you pass this phase effectively, your beagle will be a healthy dog in the future; this means fewer visits to the vet and a happier environment!
