By Nicole Cosgrove


Taking on any new puppy is exciting but it can also be nerve-wracking and worrying. One of the greatest concerns for most new owners is knowing whether their dog is growing at the right speed.

Whether you think your Beagle is growing too quickly and is at risk of becoming overweight, or too slowly and you’re worried about illness and other potential problems, knowing their ideal weight at different stages of their life can give you peace of mind. Using our chart and information below, you can determine what size your puppy should be, but do remember that not all puppies grow at exactly the same speed. Even within breeds, males and females will grow at different rates, while some puppies simply grow slower than others.

Your choice of diet, amount of exercise, and the general health of your puppy are some of the factors that might determine exactly how quickly they grow and what size they grow to.

Facts About Beagles

Beagles are fun-loving, energetic, bright, and playful. They are still used as working and hunting dogs around the world but have become equally popular as family companions. They date back to the 14th century and come from England. Whether you keep one as a working dog or introduce them to your family, you should expect a canine companion with an incredible sense of smell.

Expect them to be muscular, especially if they tend to work in the fields all day, and train them from a young age if you want to limit their vocalization.

As well as requiring a lot of daily exercise, the Beagle is also known for being very vocal. Without training, he will bark when hungry, when it is time to be let outside, when he wants to come back inside, and just because you’ve returned home. Training may not eliminate barking completely, but it can be used to teach your dog when it is acceptable to bark and for how long.

You need to take good care of your pet while they are growing, so you can use our calculator tool to help you know how much to feed your pup and keep their well-being:

The exact amount of calories an individual animal needs to maintain a healthy weight is variable and influenced by many factors including genetics, age, breed, and activity level. This tool is meant to be used only as a guideline for healthy individuals and does not substitute veterinary advice 

Divider 4Beagle Growth Stages

Different dogs do develop at different speeds, but there are some general guidelines that you can follow. Below, we have included the stages of puppyhood so you can see how well your furry friend is developing.

8-week-old (2 months) Beagle

You can start introducing puppy food to your Beagle’s diet at around 6 weeks, which is when he will start to run and bark. At 8 weeks, he will start to nip. His littermates will usually be the ones to teach him that this behavior is wrong. At 8 weeks, you can enjoy some basic play with your puppy. However, it should be gentle and you shouldn’t be too rough. You can also enroll in puppy classes to encourage your dog to socialize with puppies from other litters. You should still avoid dog parks. This is the age when most puppies are adopted.

12-week-old (3 months) Beagle

This is the age when puppies start to transition to young dogs. Their coordination will improve greatly, they will start to learn what is safe and unsafe, and their fear response will diminish. Your puppy should weigh around 10 lbs by this age, and they should start to develop some independent action by this stage, too. House training should start at this age and general training should have started by now. Negative experiences can still leave a lasting impression, so guests and family members should still take care while handling the puppy.

At this age, you should be looking to discourage him from biting hands and to play with toys instead.

6-month-old Beagle

At 6 months, your Beagle will be at about half his full size. You can start to walk him outdoors and potty training should be close to complete, if not fully complete, by now. His attention span will continue to increase, which will make it easier to teach him more advanced commands, and more of them. Your Beagle’s exceptional sense of smell will really start to develop at this age, and you should allow him to stop and sniff his environment. This is the age when you would usually get your dog spayed or neutered.

By the age of 12 months, your Beagle will have nearly reached full size, although this breed does not reach full maturity until 18 months old. Your hound may get a little taller and fill out a little more over the next few months, but by this stage, you will have a good idea of whether you have a 13” or 15” Beagle. Your puppy should be well underway with training, be well socialized, and be on his way to becoming an intelligent and highly skilled hunting dog.Divider 7

When Do Beagles Stop Growing?

Beagles stop growing by the age of 18 months. Their skeletal system has reached full maturity and their weight should remain steady after this point. A male Beagle should weigh around 25 lbs and a female 22 lbs. Expect to provide an absolute minimum of one hour of exercise each day. Your Beagle will eat between 1 and 1.5 cups of food per day. If he is an active dog, he will require more food.

How Does Neutering/Spaying Affect My Dog’s Growth?

The exact age at which you spay or neuter your dog will determine how much and for how long they grow. Recent research indicates that dogs that are neutered early will actually increase the amount of time that their bones grow. This results in a taller dog, but it does not necessarily mean that they will weigh more. Unfortunately, it may also affect how your dog’s joints align, so you will need to keep an eye on their musculoskeletal development to ensure there are no problems.

Although spaying and neutering do increase life expectancy, eliminate unwanted puppies, and can help eliminate behavioral problems, early spaying or neutering is not in the dog’s best interests.

Dangers of Growing Too Quickly or Stunted Growth

A puppy that is growing too quickly can become overweight or obese. It can increase the likelihood of developing conditions like diabetes mellitus and heart complaints. It is most commonly caused by overfeeding your puppy. You should weigh the amount of food you feed your dog and adjust the total food you give according to age and activity levels. Some health conditions, such as hypothyroidism and hyperadrenocorticism, may also lead to weight gain.

Stunted growth could be a case of genetics and could be caused by worms or intestinal parasites. Stunted growth is not a common problem in Beagles but may occur and will require veterinarian tests to confirm.

Divider 5Conclusion

Healthy growth levels vary by breed, gender, and even the individual dog and their genetics. However, the ranges above are a good guideline for how quickly your puppy should grow and what size they should achieve by a certain age.

By the time your dog reaches 12 months old, they will have nearly reached full maturity, but they may grow a little more over the next six months. Feed according to their size, don’t get your dog spayed or neutered too early, and have them checked if you experience any sudden or stunted growth. This will help ensure steady and healthy growth that is ideal for your Beagle puppy.
