Beagle Puppy Development Stages

Beagle Development

Birth – 2 Weeks

The birth of the Beagle puppies happens after nine weeks inside their mom’s womb.

When puppies are born, the ears and eyes remain closed and hence can’t hear or see anything. Every puppy needs the mom’s closeness to absorb their mom’s body heat.

Puppies grow fast and by the end of the first week, they are double their weight.

During week two, the puppy will start opening their eyes but cannot see well. This pup at this stage continues to grow weight but still needs to be around the mom.

3 Weeks – 12 Weeks 

During the third week, the puppy’s sight will improve and the ears will open. The puppy can now stand up and walk a few steps.

They can start socializing with their littermates and their mom. Between 4 to 6 weeks old, the Beagle puppy develops their true personality.

They begin running, walking, and whining, and they can also bite. Puppies can eat puppy food in their diet.

At around 7 to 8 weeks, the puppy learns the necessary socialization skills from the mom and littermates.

They start nipping and biting about everything. The pup learns that it’s not right to bite from the mother and littermates.

8 to 12 weeks is the right time to get yourself a Beagle puppy and begin a life together. Your puppy at 12 weeks can start house training, and crate training and teach them socialization.

4 Months – 9 Months

By 4 months, your puppy is quite energetic and playful hence necessary to continue with their training. You can begin taking them for short walks and teach them some tricks and some basic commands.

By 6 or 7 months, your Beagle pup will be halfway through his body growth. The female puppy could already be on their first heat.

10 Months – 18 Months

At 12 months the Beagle is nearly about their full size, however, they reach full maturity at 18 months and may fill out a little more and get a little taller between 10 months and 18 months.

Beagle Size

The dog’s paw size is directly related to the length of the dog’s legs. The larger the paws grow, the larger the do will grow. When a dog has long legs, it means it will have a larger frame.
