At What Age Do Beagles Stop Growing?

Beagles are a highly sought after breed of dog. They tend to be on the smaller side, but I was wondering when the actually stop growing. This is what I’ve learned about the average growth of a Beagle.

At What Age Do Beagles Stop Growing?

Beagles stop growing at about 18 months. At this age, their skeletal system will be completely developed and will remain steady. Fully grown a male Beagle will be about 14 to 16 inches tall and weigh 22 to 24 pounds, while a female Beagle will be about 13 to 15 inches tall and weigh 20 to 22 pounds.

This is just the beginning of your Beagle’s growth. If you are interested in what age your Beagle should be hitting certain milestones, and what to watch out for as your beagle grows, keep reading.

Birth to Two Weeks Old

When Beagles are first born they will keep their eyes closed making it so they can’t see anything. They will also not have any baby teeth. They should be starting to stand and at least attempting to walk by two weeks old. They should weigh about 1 pound.

Three Weeks Old

At three weeks old your Beagle should begin to open their eyes, their vision should start to become clearer and they will become more alert. They will also begin to develop their hearing and become more curious. They will begin to slightly venture away from their mother. They may also begin to whimper and make sounds. They should be about 1.5 to 2 pounds.

Four Weeks Old

At four weeks old your Beagle puppy should start to become more vocal and playful with their littermates and humans. They begin to learn very important socialization skills such as the difference between biting and play biting.

They should begin to be weaned off of their mother’s milk, by having puppy food in addition to the milk. They should also be exposed to more human contact so that they can get used to being handled by humans. They should be about 2.5 to 3 pounds.

Six to Seven Weeks Old

At six to seven weeks old your Beagle will become much more curious. They will be used to being around humans and common household noises making them more courageous (make sure to puppy proof the house).

They should begin responding to their name and be more aware. They should also be almost completely off their mother’s milk. They should weigh about 3.5 to 4 pounds.

Eight Weeks Old

At eight weeks old the Beagle should not have to rely on its mother anymore and should be responding to its name and simple commands.

At eight weeks old your Beagle will be ready for training and eat regular puppy food. They should weigh about 3.5 to 6 pounds.

Sixteen Weeks Old

At sixteen weeks old your Beagle should be able to understand and do basic commands and respond to their name. They should also have, being potty trained down. They should weigh 8 to 12 pounds.

Six Months Old

At six months old, your Beagle should be switched from puppy food to dog food. Puppy food has a lot of calories to help your rapidly growing puppy get the nutrition they need, but once they hit six months their growth will begin to slow down and they risk the danger of getting overweight if not switched.

It may take a few weeks to get them fully switched over to dog food. They should weigh about 10 to 15 pounds.

One and a Half Years Old (18 months)

At 18 months your Beagle should be fully grown and trained. As Beagle Pro says about it, “The adult skeletal system is now completely formed and weight will also remain steady.

The Beagle well trained, socialized and able (and wanting) to exercise at least twice per day. It is recommended to offer a steady walk of 1 mile and the 2nd dose of cardio exercise.” They should weigh about 20-24 pounds.

When Are Beagles Fully Grown?

Beagles are considered small dogs and don’t get very big so it can be difficult to know when they are done growing. There are a few things you can look for to determine if they are done growing, or not.

The first and most telling sign for a fully grown Beagle is their age.

Beagles will usually stop growing at 18 months or 1.5 years. At this age their Skeletal System is fully developed and will normally stay stable and not grow anymore.

If you have adopted or rescued your Beagle and are unsure of how old they are there are other signs that will help you to figure out if your Beagle is fully grown or not.

One sign is by their height and weight. Adult Beagles will be anywhere from 13 to 16 inches and should weigh anywhere from 20 to 24 pounds. This will change depending on if your Beagle is a male or female.

Males will usually be bigger than females ranging from 14 to 16 inches tall and weigh 22 to 24 pounds, while females will be on the lower end of the scale ranging from 13 to 15 inches tall and weigh 20 to 22 pounds.

“Looking from above, he or she should have some definition to their waist. You should be able to feel their ribs and possibly see just a hint of them if you look from the side… Their tummy shouldn’t hang down, but don’t confuse this with a barrel-shaped chest. My beagle Clayton, even when he is on the thin side of normal, can look a bit stout due to his chest shape. Beagles who are closer to the breed standard, however, tend not to have this characteristic.”

Making Sure Your Beagle’s Growth is Healthy

To make sure your Beagle’s growth is healthy, make sure to watch their growth and keep track of milestones to make sure they are developing as they are supposed to.

Not every Beagle grows the same so it’s okay if they hit their milestones a little bit early or a little bit late. If they are way behind developmentally it is best to take them to a vet as something may be wrong.

Make sure that you don’t over or underfeed your Beagle especially when they are still growing as a good diet will help them to grow and develop properly.

If you have any concerns, or think something is wrong or off, take them to go see the Vet. It is better to be safe than sorry especially when dealing with your pet.

Be cautious of people trying to sell “Pocket Beagles”. These are Beagles that are bred to essentially be miniature beagles, but there are no modern Pocket Beagles. These are just Beagles that have been bred poorly or incorrectly and will have many health issues and stunted growth.
