The critical periods begin at day 1
Day 1 to day 21
The first 48 hours are the most vulnerable time for new bourns, we check our puppies and mother about every hour to make sure they are eating and are kept warm. Mom usually spends the first few hours resting due to exhaustion from the birth of the litter. After the first 48 hours she will take over. Puppies during the first 21 days react to his or her survival needs, food, sleep, warmth, and their mother. The first week they look like little rodents.
The next 7 days
During this period the puppy’s senses begin to develop and they need their mom more in this period more then ever. They start to become aware of the new world around them and mom is their security at this time. With out their mother this could be a frightening experience.
28 to 49 days
“Pecking Order Begins”
At this time the puppies begin to venture around away from their mother and start to explore the world around them. Some start to break into groups and the so called Peking order begins. At 4 and a half weeks we start to feed our puppies mashed puppy chow and usually once one starts to eat they all will eat. The first few days are very messy, they are walking through their food and some even lay in it. By week 6 we try to have all weaned off of mom away from her. We take them all to our Veterinary and they are given a complete physical and their first set of shots. They all receive health certificates and begin some outside activities. We now let people start to see them and socialize with them. The puppies stay with us until week seven by this time he has experienced some competition from his or her litter mates and their personalities are beginning to form and it is time for their new owners to develop that personality.
