My Dog does not bark, how to make him little aggressive?

1 - Pull his tail.2 - Beat him, because even he is a dog, he does not bark. 3 - throw out him from the house. :) :)

I think you should try to know more about dogs before adopting one.. That was quite a stupid question. What is the purpose of you having a dog first answer that question!!

First treat your as a family member... Trust me u don't want a aggressive dog... Dogs have naturally guarding temperament... So don't try to make them aggressive... Just treat them as ur friend and companion... And first of all he is just 2 months old puppy... He as plenty of time for guarding you and your family... Start ur basic Training from 3 month... Just watch some ceasor melon video for training..
