Key Takeaways
Renowned for their unique curiosity, hunting roots, and friendly disposition, it’s easy to see why the Beagle remains one of the world’s most beloved breeds. Originally bred as hunting dogs for jackrabbits, today, this adorable breed is used as a family dog, a detection dog in agricultural settings, and even for search and rescue!
If you’re thinking about adopting a Beagle, or already your own, it’s of the utmost importance that you understand the proper growth and weight ranges of this breed. This ensures that your dog is growing according to the average development milestones and is equipped to live a long and healthy life. Good nutrition, proper exercise and enrichment, and high-quality veterinary care all play a role in the long-term well-being of your Beagle.
Keep reading to learn more about your Beagle’s growth patterns, the different developmental stages they go through, common questions, and other useful information!
Beagles were bred in England in the mid-1800s, though their original heritage and exact origin remain unclear. They are curious and playful and require a fair amount of space for exploration and exercise. They have a fairly long life expectancy (around twelve to fifteen years) and usually get along well with people and other animals.
Beagle puppies are born blind and deaf and are extremely small. They are also fully reliant on their mother, who they rely on for warmth and nutrition. Beagle puppies experience rapid growth in their first few months, reaching their adult height by around eight to twelve months. However, their bodies will continue to fill out until around eighteen months, at which point they usually have reached their final weight. It’s crucial to be aware that genetics play a crucial role in determining the overall size and build of a Beagle, with individual variations in height and weight.
Other factors can affect your Beagle’s final weight and height besides their genetics. Nutrition is a critical factor influencing growth, meaning that a well-balanced diet is essential for proper skeletal development and muscle growth. Overfeeding can lead to obesity, impacting the Beagle's overall health and well-being, so regular exercise is vital to support their muscular development and help them maintain a healthy weight.
If you have concerns about your dog’s weight, growth, nutritional needs, or exercise requirements, you should chat with your veterinarian. They can perform an examination to ensure that your pup is healthy, as well as provide advice and coaching regarding their health needs.
As puppies grow and age, they go through several different growth stages and developmental milestones. As medium-sized dogs, Beagles don’t take as long to reach their full size compared to larger breeds like Huskies and German Shepherds.
Understanding these different stages and what they entail is crucial for meeting your Beagle’s needs during each of them. Let’s dive into them below!
The first two weeks of a puppy’s life are referred to as the neonatal stage. During this timeframe, puppies cannot see or hear and are not yet able to walk. Within a week, their weight will have doubled, and by the end of the second week, their eyes will begin to open. They’ll also continue to grow and take their first steps towards socialization by vocalizing their needs to their mother. During this time, gentle and careful handling by a human caretaker can help produce positive effects on the puppy’s nervous system and motor skills.
Next is the transitional stage, which occurs from two to four weeks. While puppies are in the transitional stage, they’ll begin to sit up, stand, and even walk a little. Their ears will open and they’ll begin to hear and interact with their surroundings a bit more. They’ll also begin to lose their milk teeth and develop back teeth. Puppies will begin to play with their littermates, developing and learning critical socialization skills. The mother will also spend more time away from her pups and nurturing them, allowing them to develop their sense of independence.
The socialization period lasts from four to twelve weeks. By around six to eight weeks, your Beagle should be weaned from its mother. Multiple meals throughout the day are crucial for keeping your pup satisfied. Puppies will also continue to grow very rapidly, so a high-quality, nutrient-dense diet should be carefully adhered to.
Typically, the second half of this stage is around the time dogs go to be with their new owners and are separated from their mothers and littermates. Socialization is especially important during this time, as dogs’ experiences with humans at this age will shape how they interact with people in the future. It’s also a good time to begin training your dog some basic commands, working on behavior like biting and potty training, and booking a veterinarian visit for all necessary vaccinations.
During the juvenile stage, your dog will continue to grow and begin to look more like an adult rather than a puppy. This period lasts from three to six months and includes many important milestones, like the development of strong motor skills, the loss of baby teeth, and, most importantly, sexual maturity. Your Beagle should be spayed or neutered during their time, as well as continue to receive all other necessary veterinary care like vaccines.
Chewing and teething are common problems during the juvenile period since your puppy will be losing their baby teeth. Consider providing chew toys for your dog, as well as lots of mental and physical stimulation, to help prevent related behavior issues.
It’s also important to note that many dogs experience a fear period at around four months, and may be shy and anxious. Socialization and consistency with training are key to helping your puppy grow up to be social and confident.
By the end of six months, your Beagle puppy will have reached the adolescent stage, which lasts until around eighteen months. Dogs will begin showing signs of sexual interest and maturity around this time if not fixed and will develop the rest of their adult teeth. Around eight months, your dog will have reached its final height, though their full weight will likely not be reached until eighteen months.
During this time, it’s imperative to be aware of the fact that many dogs will test boundaries with their owner. This behavior is normal and is part of the healthy development of your Beagle. However, patience and positive reinforcement can help address these issues. Training classes and socialization with other dogs can also be quite helpful in many circumstances.
Understanding and managing your Beagle puppy's growth is essential for ensuring their overall well-being. During their most rapid growth stages, Beagle puppies require a diet rich in protein and essential nutrients to support their rapid growth. As they transition to adolescence and then adulthood, a balanced diet helps promote proper bone and muscle development. It's crucial to adjust portion sizes to prevent overfeeding, as Beagles are prone to obesity.
One of the best ways to encourage healthy growth and development is with exercise. Regular exercise plays a pivotal role in fostering healthy growth. As a hunting breed, Beagles are extremely energetic. Engaging in age-appropriate activities with them helps dogs develop strong muscles and maintain a healthy weight. Controlled exercise is particularly vital to prevent joint issues and ensure overall fitness.
Monitoring your Beagle's growth involves observing various signs. A healthy Beagle should display a gradual increase in size, maintaining a proportional build. A shiny coat, clear eyes, and high energy levels indicate a healthy pup, while an unhealthy dog is likely to experience symptoms and signs such as lethargy, stunted development, poor coat quality, or even an unsteady gait.
Due to their genetics and breeding, Beagles are not as prone to health problems as many of the other breeds out there. However, like all breeds, there are certain health issues they can be susceptible to. They include:
Cherry eye is easy to spot, thanks to its distinct appearance. Damage or stress to your dog’s tear gland can cause it to prolapse, which creates the appearance of a swollen, red lump in your dog’s eye. Eye drops and compresses can help, but ultimately your puppy needs to be seen by a veterinarian. In some cases, surgery may be necessary.
Another common issue that Beagles can be prone to is obesity. Due to their size and personalities, Beagles often find it very easy to sneak extra treats and scraps from the table. However, their size and overall build of their bodies also mean that they can easily become overweight, which can cause joint problems and other health issues. Good exercise and a high-quality diet can help your pup maintain a healthy weight.
Allergies are a common problem for many dogs. Allergies can be environmental or dietary and can cause problems like a runny nose, digestive issues, and itchy eyes. Allergy medication and avoidance of food your dog is allergic to can help.
Due to their shape, Beagles can sometimes develop joint issues. Hip dysplasia is common and can also create arthritis and difficulty walking. Typically, signs of joint issues are lameness in the back paws, difficulty moving, and lethargy. Speaking with a veterinarian can help you understand what medications and other treatment options are available.
Understanding your Beagle’s needs and growth patterns can help you provide a happy and healthy life for them! To care for your Beagle, be sure to:
Beagles are medium-sized dogs and will typically stop growing around eighteen months. However, they will reach their full height by around eight.
Beagles are an extremely active breed and can have a lot of energy! They’re quite curious and need a lot of space to exercise and run around. Thus, they tend not to make good pets for people who are gone a lot or who live in apartments.
Beagles are one of the most vocal breeds out there and are very expressive. However, excessive barking can also indicate anxiety.
Beagles are excellent hunters and are often used to hunt for rabbits and other small game.
