Neonatal Period (0-3 Weeks Old)

The Border Collie puppies will start to develop and gain weight within two days of their birth. The puppies will start doubling their weight from the first week which will continue till the 6th week. On a daily basis, the puppies will gain about ½ ounces a day. If your puppy doesn’t experience the same changes, it’d better to see a vet.

Neonatal period is a period where the Border Collie puppies are very weak. So, they need extra attention and care which of course is done by their mother. During these days, make sure to keep the puppies close to their mother as they know the best for their babies. You shouldn’t bath the pups for three weeks and let their mamma do all the cleaning for them.

As the puppies will be very young, they will only be able to drink their mother’s milk. The antibiotics present in the mother’s milk will increase their immunity and help them fight any infections. It is common for the puppies to spend most of their time sleeping.

Transitional Period (2-4 Weeks)

The transitional period brings one of the most memorable moments of your Border Collie puppies that you don’t want to miss. They will open their eyes for the first time and would be able to see the world within the second week. By the end of week 3, they will be able to stand and walk slowly.

The taste buds of the puppies will develop and they will be able to taste foods other than their mother’s milk. When they become 4 weeks, they will become a little independent from their mamma. Likewise, they’ll start to wander around to explore and play with their siblings.

Socialization Period (3-12 Weeks Old)

The socialization period is the time where your Border Collie puppies will start socializing with other dogs and pets. They won’t be totally dependent on their mother’s milk and will be able to eat semi-solid food. When the puppies reach 6 weeks, they will weigh about 3 to 6 pounds, multiplying their birth weight by 4 times.
