How Big Do Beagles Get Weight: Everything You Need To Know

As a Beagle owner, one of the most common questions I get asked is, “How Big Do Beagles Get Weight?” It’s a legitimate concern, especially for new owners who are not quite sure what to expect. The good news is that there are several ways to estimate how much bigger your Beagle will get.

Beagle Size and Growth

Beagles are small to medium-sized dogs that belong to the hound group. They were originally bred for hunting rabbits and other small game, so they have a strong sense of smell and a high energy level.

Beagles come in two varieties based on their height: the 13-inch variety and the 15-inch variety. The 13-inch variety stands up to 13 inches at the shoulder and weighs up to 20 pounds. The 15-inch variety stands between 13 and 15 inches at the shoulder and weighs up to 30 pounds.

There is no significant difference in size or weight between male and female Beagles. However, individual Beagles may vary in size and weight depending on their genetics, diet, exercise, and health.

How Big Should a Beagle be at Six Months?

A six-month-old Beagle will be close to their adult height and could stand anywhere between 10 and 13 inches tall, weighing around 12 to 17 pounds.

At What Age is a Beagle Fully Grown?

Beagles are considered fully grown when they reach their adult height, which usually happens by eight months old.

However, they may continue to fill out and gain weight until they are about a year and a half old.

What is the Average Weight of a Full-Grown Beagle?

The average weight of a full-grown Beagle depends on their height variety.

According to the American Kennel Club (AKC), the standard weight range for a full-grown Beagle is as follows:

  • For the smaller variety (13 inches & under), the ideal weight is between 16 and 20 pounds.
  • For the larger variety (13 to 15 inches), the ideal weight is between 20 and 30 pounds.

However, these are only guidelines and not strict rules.

Your Beagle’s healthy weight may vary depending on their body type, bone structure, muscle mass, activity level, metabolism, and health condition.

How Do I Make Sure My Beagle is Healthy?

To make sure your Beagle is healthy, you need to provide them with proper nutrition, exercise, grooming, training, socialization, and veterinary care.

Here are some tips on how to keep your Beagle healthy:

Feed your Beagle a high-quality dog food

Feed your Beagle a high-quality dog food that meets their nutritional needs for their age, size, activity level, and health condition. Avoid overfeeding or underfeeding your Beagle, as this can lead to obesity or malnutrition. Follow the feeding instructions on the dog food label or consult with your veterinarian for guidance. Provide your Beagle with fresh water at all times and avoid giving them human food or table scraps that may be harmful or unhealthy for them. Monitor your Beagle’s weight regularly and adjust their diet accordingly if they are gaining or losing too much weight. You can use a dog body condition score chart to assess your Beagle’s body condition and ideal weight range. You can also use a dog BMI calculator to estimate your Beagle’s body mass index (BMI) and obesity risk. If you have any concerns about your Beagle’s weight or diet, consult with your veterinarian for advice.

Exercise your Beagle regularly

Beagles are active dogs that need plenty of physical and mental stimulation to keep them happy and healthy. They love to run, play, and explore, so make sure you provide them with enough exercise every day. Depending on their age and health, a Beagle may need anywhere from 30 minutes to two hours of exercise per day. You can exercise your Beagle by taking them for walks, playing fetch, doing agility, or joining a scent work club. Beagles have a strong hunting instinct and may chase after anything that smells interesting, so always keep them on a leash or in a fenced area when outdoors.

Groom your Beagle regularly

Beagles have a short, dense coat that sheds moderately throughout the year. They don’t need much grooming, but you should brush them once or twice a week to remove loose hair and dirt. You should also check their ears regularly for signs of infection or wax buildup, as they are prone to ear problems due to their long, floppy ears. It’s also important to clean their ears with a cotton ball and a gentle ear cleaner, but avoid using cotton swabs or inserting anything into their ear canal. You should also trim their nails every few weeks to prevent them from getting too long and causing discomfort or injury.

Train your Beagle consistently

Beagles are smart and eager to please, but they can also be stubborn and independent. They need consistent training from an early age to learn good manners and obedience. You should use positive reinforcement methods, such as praise, treats, and toys, to reward your Beagle for doing what you want them to do. Avoid harsh or punitive methods, such as yelling, hitting, or scolding, as they can damage your Beagle’s trust and confidence. You should also avoid giving your Beagle mixed signals or reinforcing unwanted behaviors by accident. For example, if you don’t want your Beagle to jump on people, don’t pet them or give them attention when they do so.

Socialize your Beagle early

Beagles are friendly and sociable dogs that get along well with other dogs and people. However, they need early and frequent socialization to develop into well-rounded and confident adults. You should expose your Beagle to different dogs, people, places, and situations when they are young and impressionable. This will help them learn how to behave appropriately and cope with new experiences. You should also make sure that your Beagle’s socialization is positive and fun, not scary or stressful. You can enroll your Beagle in a puppy class or a socialization group where they can meet other friendly dogs and people in a safe and supervised environment.


Beagles are wonderful dogs that can make great companions for anyone who loves adventure and fun. They are loyal, affectionate, and playful dogs that will brighten up your day with their antics and charm.

However, Beagles also need proper care and training to thrive and be happy. They need enough exercise, grooming, training, and socialization to keep them healthy and well-behaved.
