Dog Life Stage

They can also set competitive games (of strength, possession, etc.) aimed to find out what is the dominant dog. They learn to express their feelings through the games and also to assume (and find out) their own social status. At this age, it's very usual for the puppies to begin showing themselves strangely fearful, expressing their fear to objects or people they are already familiarized with.

Forcing the dog to face its fears can provoke the perpetuation of this fear. dog training collar review
