The Beagle breed is popular among American dog owners for its happy-go-lucky, affectionate nature. President Lyndon Johnson had three Beagles during his time at the White House, and Peanut’s famous Snoopy character is a Beagle himself! But these curious, intelligent dogs can quickly get into trouble if not provided with plenty of playtime and stimulation.

Originally, beagles were used as pack hounds to hunt rabbits and hares in England. Anyone in old England who could not afford to keep horses for hunting would have Beagles to chase small game on foot, earning them the name “foot hound.” If you’re the lucky pet parent to one of these playful, friendly dogs, you may be asking yourself: how big are Beagles fully grown?

Here’s everything you need to know about Beagle size and growth:

Beagle Growth and Size

Unlike many dog breeds, Beagles do not vary much in size based on gender. However, the American Kennel Club currently recognizes two varieties of Beagles in size: the “13 inches & under” size and the “13 to 15 inches tall” size.

A Beagle’s adult height largely determines what their healthy weight should be, which can vary by about 10 pounds depending on their size classification. If you purchased your Beagle puppy through a breeder or pet store, reach out to them about the Beagle size group your puppy belongs to. If you’re unsure which group your Beagle falls into, you can measure their height yourself.

Please remember that the following numbers are estimates and that all puppies grow at different rates. Don’t worry if your puppy is slightly ahead or behind the following numbers. Consult with your veterinarian if you’re concerned about your Beagle’s weight or size.

Pro Tip: Did you know that you could be reimbursed for up to 90% of your dog’s veterinary bills? Compare Beagle health insurance options now.

How big should a Beagle be at six months?

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

How much bigger will my Beagle get?

There are a few ways to estimate how much bigger your Beagle will get.

Most Beagles reach their adult height by eight months old and their adult weight by a year and a half of age. If your Beagle is less than a year and a half old, they are likely still growing. Reference our growth chart above for estimates on your Beagle’s final size.

You can also take a look at your Beagle’s paws. Do they look large next to their body and legs? This is a classic puppy feature showing that your Beagle pup is still growing into them!

If you purchased your Beagle through a breeder, you could contact them for a more exact estimate of your Beagle puppy’s final size and height based on previous litters by their parents. What size group they fall into based on their expected adult height can provide a lot of clarity on how much they will eventually weigh.

At what age is a Beagle fully grown?

Beagles reach their full height around eight months old and their adult weight around 18 months old. That’s not to say they won’t get any heavier, however. Beagles are particularly prone to obesity.

These “chowhounds” tend to over-eat and should have their food carefully portioned out, as they’ll continue to eat well beyond the point of being full. As a Beagle owner, it’s vital for you to closely monitor their weight and diet to help them avoid the dangers of obesity.

What is the size of a full-grown Beagle?

The American Kennel Club’s Official Standard for the Beagle breed states that an adult Beagle standing at 13 inches or less should weigh less than 20 pounds, while an adult Beagle standing at 13 to 15 inches tall should weigh between 20 and 30 pounds. As adults, Beagles will look like miniature foxhounds with a solid, balanced body that allows them to last in a long chase.

How do I make sure my Beagle is healthy?

According to the Veterinary Centers of America, Beagles are more prone to specific genetic health problems, such as cervical intervertebral disk disease. This disease occurs more frequently in dogs with long backs and short legs between three and six years old.

Watch out for symptoms like neck pain, a change in their gait, or lowered head, possibly with muscle spasms in their shoulders, neck, and head area. If you notice your Beagle experiencing these symptoms, immediately contact your veterinarian for the next steps in treating your pup.

Regular veterinary care is the best thing you can do for your dog’s long-term health. A veterinary professional can regularly screen your Beagle for common health problems, like diabetes, and work with you to prevent and treat any health concerns that arise.

Veterinary care can become expensive, especially for emergency or unexpected treatments. Only 19.44% of pet parents surveyed said they would be able to pay for a $5,000 veterinary expense out-of-pocket, leaving many pet parents in a dangerous position should anything happened to their beloved dog.

Pet insurance is the answer to this dilemma. Pet insurance works by reimbursing you for up to 90% of out-of-pocket veterinary care so that you can provide your Beagle with the best care. Like humans, dogs are living longer lives and require top-notch health care to enjoy their happiest and healthiest lives.

Pet insurance provides you with a safety net so that you can give excellent veterinary care to your dog, no matter the cost. Set up a safety net today so that you can provide your pup with exceptional care throughout their entire lifetime. Pet insurance wellness plans also offer help with routine care, such as dog dental cleanings.
