Written by Adriana

No one can argue that beagle puppies are some of the cutest puppies around. But caring for your sweet pup goes beyond just adoring them. You need to be able to feed them properly as well. Part of that is knowing how to read a beagle growth chart in order to know whether your puppy is on track for a healthy adulthood.

As you monitor how well your dog is growing and whether he is gaining too much or too little weight, you will be more in tune with your puppy’s needs, setting him up for a long and healthy life.

When Do Beagles Stop Growing

Beagle Puppy Growth Chart

Since beagles are such a popular breed, asking when they will stop growing is a common question. In general, beagles are considered small to medium-sized dogs. They should reach their final size when they are about 18 months old. It is at this time that their skeletal system has been fully developed and they will be able to build on their strength.

An adult beagle is 13 to 16 inches in height and should weigh somewhere between 18 and 30 pounds, but this does vary dog to dog. Female beagles will be smaller than male beagles as well, so there might be some variance there.

Beagle Weight Chart 

Consulting with a beagle weight chart will help give you some guidance about what you should expect to see from your puppy during his growth. While a puppy’s final size cannot be deduced from his birth size, at around 8 weeks of age, you should be able to get an idea of how large your puppy will be.

When you are looking at the beagle weight chart, you will want to line up the weight that you puppy was at 8 weeks of age in order to know which path that you should follow to ensure that your puppy is staying on his growth curve. For example, if your puppy is 5 pounds at 8 weeks, you can follow the chart to know that he should be about 10 pounds by 16 weeks.

The chart really is just a guide and your puppy might not adhere to it perfectly. You can get an idea as to whether your beagle is the right size by looking at his waist. You should be able to clearly see his waist and should be able to feel his ribs if you pet along them. You will know your pup is overweight when the waist disappears and underweight if you can easily spot his ribs poking out.

Beagle Growth Chart – What To Expect

Beagle Development

Birth – 2 Weeks

When your beagle puppy is just starting out in life, he is not going to weigh much. He should weight around a pound and really won’t start walking until he hits the 2 week mark. Food-wise, he is only going to be relying on his mother for milk. As he will be born blind, the mother should stay close to her pups and feed them on demand.

Your puppy will not be ready for or interested in puppy food at this point. You would only need to intervene with feeding if your puppy isn’t thriving or getting enough milk from his mother. 

3 Weeks – 12 Weeks

There is incredible growth that happens between 3 weeks of age and 12 weeks of age. When they are born, they will weigh a mere few ounces, but by 12 weeks of age, your beagle could weigh anywhere from 6 to 9 pounds. The range has to do with the sex of the dog and his genetic predisposition.

There will be growth spurts throughout this period as well, where your puppy will require more food than he might at other times. He should not be on puppy food until he is about 6 weeks old and starting to wean from his mother.

4 Months – 6 Months

Between 4 and 6 months of age, your beagle puppy could gain anywhere from 5 to 10 pounds, depending on your pup’s size. 

You should be feeding your puppy three meals a day up to 6 months, giving him even quantities at each meal. His appetite might ebb and flow through this age as he goes through growth spurts, so just keep a visual watch on his size to make sure he is eating properly.

7 Months – 9 Months

If you consult a beagle puppy growth chart, you will see that your beagle puppy will still be growing steadily between 7 and 9 months of age. His weight will be increasingly quite a bit still and he will still be eating voraciously. Since beagles do have a tendency to be overweight, do not just assume that the big appetite means that your puppy needs more food.

Pay attention to how he looks physically and how active he is. You should also reduce his meals to just twice a day, evenly splitting his daily food.

10 Months – 12 Month

Your beagle puppy will still be gaining weight between the ages of 10 and 12 months, but the amount that he will gain depends greatly on the size of dog that he is naturally. Bigger beagles will still be gaining a half a pound to a pound a week, whereas smaller beagles might gain a third of a pound of a week.

Your puppy should still be on puppy food at this point and still be eating two meals a day. You will also need to be exercising him to keep him as healthy and fit as possible. 


By the time that your beagle puppy has reached 12 months of age, he will need to be switched to adult dog food. Since puppy food is so high in calories, you will not want your beagle to eat it any longer than is necessary. He will not be completely full growth until about 18 months and you can expect to see some weight gain up until that point.

Stick with two meals a day at this point as well and your beagle will need plenty of exercise to stay as healthy as possible, not just as he is growing, but always. 

Beagle Body Shape Changes

Younger puppies are naturally rounder and softer than adult dogs are. As their bodies continue to grow you will see some shape changes along the way. When you are looking at your beagle from above, you should be able to see the definition in their waist easily, meaning that it does go in more right around the waist.

You should be able to feel your dog’s ribs easily, but they should not be stuck out. They do have a barrel-shaped chest, so it will be round naturally and make your dog appear stouter than he might really be. Not all beagles have a barrel chest, so do not be surprised if you do not see anything like that on your beagle.

Factors That Affect Beagle Puppy Growth 


Genetics is s a huge factor that affects the growth of all dogs, beagles included. Dogs are predisposed to being a certain size, depending on the size of their parents.

If a beagle has larger parents, he is more likely to be large or if his parents are small, he will be small. You cannot determine a beagle’s final size at birth, however. You will not know whether your beagle is predisposed to being bigger until he is already a few weeks old. 


Nutrition is vital to the growth of any puppy. When a puppy is able to eat a completely balanced and nutrient-rich diet, he is more likely to grow larger and stronger than a puppy that has been deprived of the best nutrients.

A growing body that is not getting enough will not have enough energy to spend on growing, resulting in a smaller dog. It is important to confirm with your vet that you are giving your pup the right nutrition.

Physical Activity & Health

Your puppy needs to have a healthy and active lifestyle in order to set him up for a nice, long life. If you can help keep his weight at an appropriate level through good exercise and diet, your puppy will be able to growth strong, lean muscles and will be much less likely to develop health issues in the future, since beagles do have a higher risk of obesity.

How Long Are Beagles Pregnant?

Beagles have the same gestation length as any other dog breed. In general, you can expect your beagle to be pregnant between 58 and 68 days. It averages right around 63 days if you are counting from conception.

Beagles Pregnancy

If your beagle was already overweight, pregnancy might not be easily identifiable with the weight gain and you could just assume that your pup is getting more overweight rather than being pregnant. If you have no plans to breed your beagle, it would be best to spay your dog before you find yourself with an unexpected littler of adorable puppies. 

How Many Puppies Do Beagles Have?

Litter size is one of those things that is very hard to determine ahead of time. After all, a dog could have as few as one pup or ten pups at a time. Since beagles are medium-sized hound dogs, they will have around 6 puppies on average, but this amount various dramatically from dog to dog.

You can know how many puppies are on the way by having your veterinarian do an ultrasound to see what you are dealing with. Otherwise, it will be a complete surprise when the puppies are born.

What If My Beagle Is Not The Right Weight

Before you panic about whether your beagle puppy is the right weight or not, you should consult with the beagle growth chart. Your puppy should be on his own growth curve through his puppyhood. If he is growing along his curve, you have nothing to worry about. If your puppy has veered off of his growth curve, it would be best to take him into the vet to figure out what is happening.

Also remember that there is a lot of variety in size from dog to dog so even if your dog is not perfectly on the beagle growth chart, there might not be anything wrong with his weight. Just like with humans, beagles can come in different sizes. As always, if you do have some concerns about the weight and health of your beagle, you need to ask your vet before you do anything else.

What Is The Life Expectancy Of Beagle?

The typical life expectancy for a beagle is between 12 and 15 years, since they are medium-sized dogs and should live longer than their larger counterparts. Their longevity is greatly affected by their overall health, however. If your beagle does develop obesity or any other medical issue, your dog’s life expectancy will be shortened.

Meanwhile, the better care you take of your pet, the longer life you are setting him up to have. The life expectancy of any dog can be improved through good diet and care, but living beyond 15 years is still unusual. 

How Much Does It Cost To Own A Beagle?

When looking at the cost of owning a beagle, there are a few things to look at. The first is the cost of adoption which can vary dramatically, depending on where you are getting your beagle from. Adopting from a breeder will cost substantially more than rescuing one from a shelter.

Then, you have to think about food. Beagles cost around $10 a week to feed, depending on the type of food that you are using. Additionally, since they do have a risk of several medical conditions, you will need to think about medication and vet visit costs as well. 

Beagle Genetics And Common Health Problems

Beagles do have a risk of developing some health issues. A common genetic disorder for beagles is dwarfism that will calls poor development of the cartilage. These pups will have short legs and degeneration in their spines.

Chinese Beagle Syndrome is another common genetic disorder. This is where your beagle will have short, upright front toes, like they are walking like a ballerina. Both of these conditions will be identifiable from birth.

Beagles do have a risk of being diabetic as well. They can develop Type 1 genetically but also can develop Type 2 through overeating. Beagles do have a higher risk of epilepsy as well.
