Phases of development

The Puppy passes through several stages of development after birth.

Vegetative phase (1. and 2. week)
In this early stage eyes and ears are still closed, and the sense of smell is poorly developed.

Transition period (3. week)
Now the palpebral fissure and outer acoustic meatus open up, still the Puppy is not able to see. Vision is not developed before the 17th or 18th week. The same applies for the sense of hearing. Did the Puppy so far solely sleep and drink, he’ll now be able to notice his siblings and adjacencies.

Filial Imprinting (4 – 7. week)
Eyes, nose and ears are fully developed. In this period the Puppy ideally becomes acquainted with various impressions like humans, noises or visual impressions. He consciously notices his environment und gets to know his social partners. While playing with his little brothers and sisters he will learn to find his position in the hierarchy and to test himself and the others. This is the period where personality and temper are stamped. Is a Puppy in this period kept isolated and without social contacts, it is very likely that there will be major problems with the dog’s socialization.
