In 2007 when Russian President Vladimir Putin took his giant dog Labrador when he went for a conference with Germany's Angela Merkel. Having attacked by a dog in the year 1995 Merkel was obviously scared by proximity of an offensive looking dog. An apology has come a bit too late. CNN on 12 January 2016 explained that he didn't mean to scare while Merkel said he did this to prove that he is a man. He is afraid of his own weakness. US will have to ensure that their female Head of Nation is not scared of any animal. Thankfully cockroach is not a pet animal.
In the year 2006, during G8 summit Bush had rubbed Merkel up the wrong way(The Guardian). Many countries might be waiting for their chance when a female takes over as President of US.
