Beagle 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

When introducing puppy food to your 8-week-old Beagle’s diet at around 6 weeks, you embark on a crucial stage in their growth. At this age, your Beagle is beginning to explore the world, running around with youthful energy and starting to bark. This is a delightful milestone in their development, marking the transition from milk to solid nourishment.

By the time your Beagle reaches 8 weeks, you may notice them starting to nip. This behavior is entirely typical and is an essential part of their learning process. It’s during this period that their littermates play a vital role in teaching them that such behavior is wrong. These early interactions with their siblings help shape their social and behavioral development.

As a responsible Beagle owner, you can engage in some basic play with your 8-week-old puppy. However, it’s crucial to be gentle and avoid being too rough. This gentle playtime not only strengthens your bond with your Beagle but also ensures positive reinforcement and a safe environment for their growth.

12-week-old (3 months) Beagle

At 12 weeks of age, Beagle puppies are at a crucial stage in their growth and development. These young dogs are beginning to transition from infancy to more independent creatures, marked by improvements in their coordination. As Beagle puppies grow, they become more confident and less prone to reacting fearfully to new experiences.

In terms of physical development, a 12-week-old Beagle should weigh around 10 lbs. This weight milestone is an indicator of their overall health and growth progress. This age is also crucial for training. House training should commence during this period, as puppies become more receptive to learning and adapting to their environment. General training, which encompasses basic commands and behaviors, should have already begun by now.

6-months-old Beagle

At 6 months of age, your Beagle enters a crucial stage in its development. At this point, your Beagle will have reached about half of its full size, signifying a significant milestone in its growth. It’s the perfect time to begin taking your Beagle for walks outdoors, fostering a healthy exercise routine that is essential for their physical and mental well-being.

One of the key achievements you can expect at this stage is the completion of potty training. By now, your Beagle should be close to, if not fully, potty trained, marking a significant relief in your daily routine. This milestone showcases your Beagle’s growing attention span, which continues to improve, making it easier for you to teach them more advanced commands.

Your Beagle’s exceptional sense of smell will truly start to blossom around this age. Encourage them to explore their environment, allowing them to stop and sniff around during your walks. This sensory development is a fascinating aspect of your Beagle’s growth and can be a source of joy for both you and your furry companion.

However, it’s important to note that Beagles don’t attain full maturity until they are 18 months old. During this period, your hound may undergo some subtle changes, such as growing a bit taller and filling out its frame, though not yet reaching its final dimensions of either 13 inches or 15 inches, depending on the variety.

12-months-old (1 year) Beagle

Your Beagle, now in the puppy stage, should be well underway with training. This crucial aspect of their development ensures that they become not just well-behaved companions but also highly skilled hunting dogs, showcasing their innate intelligence. Moreover, socialization is key at this age, helping your Beagle grow into a well-adjusted and friendly member of your family and community.

Factors that Affect the Growth of a Beagle

There are a few factors that can affect the average growth of your beagle pup.


When considering the factors that affect the growth of a Beagle, one crucial aspect to contemplate is the influence of sex hormones. These hormones play a pivotal role in determining when a Beagle will stop growing naturally. However, responsible pet owners often opt for neutering or spaying their Beagles at an early age. This decision can have a significant impact on the growth plates of the Beagle, causing them to become larger and taller than usual.

Neutering and spaying are essential procedures for managing a Beagle’s reproductive health, but they also have broader implications. By performing these procedures at an early age, you can help regulate the Beagle’s growth, preventing it from exceeding its average size. This is crucial as Beagles growing over their average size can be susceptible to several joint concerns and health issues.

Poor Diet

In the context of factors that affect the growth of a Beagle, the importance of a healthy and balanced diet cannot be overstated. An unhealthy diet can hinder a Beagle’s growth potential, preventing it from reaching its optimal size and vitality. Ensuring that your Beagle is fed a nutritious and balanced diet is crucial to promoting its overall well-being and development.

Beagles thrive on a diet that provides them with the essential nutrients and energy they need to grow healthily. An unhealthy diet, on the other hand, may lead to stunted growth and a host of health issues. Therefore, it is imperative to prioritize a diet that supports optimal growth for your furry companion.


In the realm of genetics, the growth patterns of beagles exhibit fascinating parallels with those of humans. The intricate interplay of genetic factors in beagles, much like in our own species, plays a pivotal role in determining when they cease growing. To gain insight into this nuanced process, breeders serve as invaluable resources. By engaging with a breeder, one can embark on a discussion regarding the anticipated closure of the doggy growth plates in a beagle.

However, it’s essential to note that genetics is not the sole determinant. Various medical conditions may exert their influence on the timeline of a Beagle’s growth plate closure and the attainment of their adult weight. These conditions introduce an additional layer of complexity to the genetics of growth, underscoring the importance of a holistic understanding of the factors at play.
