#13 It is necessary to acquaint the puppy with friendly dogs and people, so that later the puppy does not develop aggression or cowardice caused by the fear of new things and the inability to communicate, make new acquaintances.
#14 In the classroom at the age of 4-5 months, it is already possible to show perseverance and exactingness.
At the same time, the most important thing is not to overdo it, remember that classes should bring joy to both you and your dog, and only then can you achieve the desired result.
#15 At 6 months, the puppy begins puberty and a real rebel wakes up in him.
He begins to re-check the boundaries of what is permitted and, at times, deliberately does not respond to your commands, just to look at your reaction. If she is not what the puppy expects to see her, then he may decide that now you can no longer follow your commands.
