Age dynamics of development and variability of properties of the nervous system type was studied in the same animals (31 dogs) at the age from one month to ten years. Individual typological differences in the properties of the dogs' nervous processes were clearly manifested at the age of four to seven and a half months. Three phases were singled out in the development and variability of the properties: I--development phase; II--stabilization phase; III--extinction phase. In ontogenesis, the dogs displayed great differences in the degree of manifestation and the beginning of the phases. Relative stabilization of nervous system properties already set in by the beginning of puberty in dogs of the weak type (seven months of postnatal life) and at mature age in dogs of the strong type. Some elements of general behaviour of dogs of different nervous system types and the duration of the animals life, in relation to the nervous system type have been outlined.
在31只年龄从1个月到10岁的同组动物（狗）中，研究了神经系统类型的发育年龄动态及其特性的变异性。狗的神经过程特性的个体类型差异在4至7个半月龄时明显显现。特性的发育和变异分为三个阶段：I——发育阶段；II——稳定阶段；III——消退阶段。在个体发育过程中，狗在各阶段表现程度和开始时间上存在很大差异。弱型狗（出生后7个月）在青春期开始时，强型狗在成年时，神经系统特性已相对稳定。概述了不同神经系统类型的狗的一些一般行为要素以及与神经系统类型相关的动物寿命时长。
