Our rescue is puzzled as well. Initially we thought it was a joke but our cyber security expert this is a someone from Yemen who knows his (their) stuff.
Here's one possibility: German shepherds served effectively as MWDs in Iraq and Afghanistan. Maybe the a-holes think these are the dogs (they aren't).
Maybe this will help you.

It goes back much further than that, I read a biography of mohammad written in 1913 by Edward, Canon Sell, in which it's quite clear, mohammed hated dogs because they warned the people in the village he and his raiding party were coming to attack them. Mohammad also had a follower in his band named Osama. He was the one who set fire to the huts and houses. There's nothing these twisted evil people do, that hasn't a foundation in the life of the psychopath they call a prophet.
