You dont need to bother when there is real danger this do will without you even realising it attack & protect you.
I have a street dog & uptill now was very calm & would go wagging his tail to everybody, but just a few days back my dad was all alone in the house, & some sales man came at the gate to show something to my dad & my father refused & told him to go away, this man insisted & would not budge & after sometime opened the gate & came upto my dad & demanded that now my dad should buy his stuff, all this while my Benji was in the house snoring away on our bed. This sales man, when my dad refused & threatened to shout for help almost hit my dad,& then my little beta Benji realising that something was not right came running & actually jumped on this man & attacked him this fellow had no time to react. My dad just could not believe what happened.He called the neighbours for help, but this fellow was so scared that he actually jumped the gate & ran.
I told you about this incident to just show you that these darling dont need to be taught anything they are so indebted to us for giving the a home & our love that they will give anything to protect us. I have two dogs one Indian Pariah, Benji & the second Tibaten Terrier Elsa, both are very protective but Benji will attack not bite but attack & protest & my Elsa will bark herself sore & wake up the whole neighbourhood.
