Beagles are a very popular dog breed. They are usually on the small side, but I wondered when they actually stop growing. This is what I’ve learned about the average growth of a Beagle.
A beagle is fully grown at around 1.5 to 2 years of age. During the first year they mainly grow in height; in the last half year they only become a bit broader and more muscular/fuller.
At what age do Beagles stop growing? They stop growing after about 18 months. At this age their skeletal system will be fully developed and remain stable. A fully grown beagle will be about 33 to 40 centimeters tall and weigh 9 to 11 kilograms.
This is just the beginning of your Beagle’s growth. If you’re interested in the ages at which your puppy should reach certain milestones and what to watch for as he grows, read on.

Chart information from BeaglePro
Birth to two weeks old
When Beagles are first born, they keep their eyes closed so they cannot see anything. They also won’t have any milk teeth yet. They should begin to stand and at least try to walk by two weeks of age. They should weigh about 0.5 kilograms.
Three weeks old
If your puppy is three weeks old, their eyes should open, their vision should become clearer and they will become more alert. They will also begin to develop their hearing and become more curious. They will venture a little away from their mother. They may also start whining and making noises. They should weigh about 0.5 to 1 kilogram.
Four weeks old
When your puppy is four weeks old, your Beagle puppy should become more vocal and playful with its littermates and people. They will begin to learn very important socialization skills, such as the difference between biting and play-biting. They should start being weaned from their mother’s milk by receiving puppy food in addition to milk. They should also be exposed to more human contact so they can get used to being handled by people. They should weigh about 0.9 to 1.2 kilograms.
Six to seven weeks old
If your puppy is six to seven weeks old, they become much more curious. They will be used to being around people and will learn common household sounds which make them bolder (make sure you puppy-proof the house). They should respond to their name and be more aware. They should also drink almost no mother’s milk anymore. They should weigh about 1 to 1.4 kilograms.
Eight weeks old
At eight weeks old your puppy should no longer rely on his mother and should respond to his name and simple commands. When he is eight weeks old, your Beagle is ready for training and eats puppy food regularly. They should weigh approximately 1.5 to 2.8 kilograms.
Sixteen weeks old
At sixteen weeks old your puppy should be able to understand and carry out basic commands and respond to their name. They should also be house-trained. They should weigh 3.5 to 5.5 kilograms.
Six months old
When your puppy is six months old, your Beagle should be switched from puppy food to adult dog food. Puppy food contains many calories to help your fast-growing puppy get the nutrition they need, but once they are six months old their growth slows and they run the risk of becoming overweight if they are not switched. It may take a few weeks for them to be fully transitioned to adult food. They should weigh about 4.5 to 6.8 kilograms.
One and a half years old (18 months)
After 18 months your Beagle should be fully grown and trained. As Beagle Pro says about it: the adult skeleton is now fully formed and the weight will also remain stable. The dog is well trained, socialized and can (and will) exercise at least twice a day. It is recommended to offer an even 1-mile walk and a second session of cardio exercise. They should weigh about 9 to 11 kilograms.
