A newborn puppy is like a baby. Its mouth, nose, ears, and foot pads are all ruddy in color. It cries when it is hungry and sleeps most of the time.
In the first week after birth, its eyes have not yet opened. It relies on its senses and smells to receive external information. It will only crawl in a small area and will not stray too far from the nest. The body weight can be doubled. If tail docking or dewolf toe removal is required, it should be done on the 4th to 7th day.
At the end of the second week, its eyes and ears slowly open, but it still cannot see clearly and responds to the ambient temperature. At this time, the puppies began to have social activities - licking and wiping each other.
In the third week, they began to learn to walk crookedly and reacted to shaking and shiny things. The puppies began to leave the mother dog and move around nearby. A male dog will roughly nudge his children with his nose to let them understand the cruelty of the outside world. When the puppies return to the nest, the rough play will stop. This is an important education method in the dog group.
In the 4th week, the female dog mother does not care about her children, and the puppies are gradually weaned. All of its feelings are fully formed during this period, and it begins to recognize and understand the external world. This period and Human contact is crucial so that it does not cause fear and aggressive behavior towards people.
In the 5th to 6th week, you should go to the pet hospital to check the feces, perform deworming and vaccination to avoid infection with canine distemper and other viral diseases. You can also start its life education, such as defecation and name-calling training, but you can't put too high demands on it, and it won't be able to complete training on complex subjects.
Playing is the best way for puppies to learn. They establish a hierarchy during play. Your authority as an owner should be established during this period, otherwise it will be difficult to discipline in the future.
Before sexual maturity at 5-6 months, simple training can be carried out, such as coming, sitting, following, etc. As an owner, you should spend more time playing and walking with your dog to promote its development. Improved brain development and learning abilities.
