Aggressive puppy

dog and cat“I have a six month old puppy (kundelka), who is aggressive towards young children. My three-year-old nephew is very fond of playing with him, and I am not in a position to watch over a child. I think about it with horror, what can happen at the moment of my inattention. Will the dog outgrow this aggressiveness?? if so, so when? Are there any injections or medications, which would help eliminate his aggressiveness?”

Character traits of dogs (gentleness, malice). These are hereditary matters. If the dog aged 6 months shows malice, the aggression will increase over time. Sedation is out of the question, because their action is short-lived. However, the constant administration of drugs will cause addiction, poisoning the dog.
