my name is Kaitlan, I am 24 years old. My relatives can also help me. Dogs are known for their learning abilities, love of the game, and social behavior. Special breeds of dogs designed for various purposes: hunting, guarding, traction of horse-drawn vehicles and others, as well as decorative breeds, have been bred. An important criterion for evaluating dogs for specialists is its constitution - a genetically determined relationship between the beneficial properties and qualities of the animal with the features of physique and behavior, which determines its service and breeding qualities. The constitution is associated with health, vitality, resistance, precocity, fecundity, life expectancy and performance of the animal. Dogs can perfectly understand the expression of a person’s voice and face and determine his intentions. Dogs are the only animals that can keep track of where a person is looking, and use this when interacting with him.
