13-year-old Emmanuel Festo from Tanzania poses for a portrait with a plush toy that he says makes him feel safe at night and that he sleeps with, in New York's Staten Island, September 21, 2015.

In this June 16, 2015 photo, an Indian coachman sleeps on his Victoria horse-drawn carriage outside a stable in Mumbai, India.

Yet that time is coming, thanks to a court order calling such superfluous “joyrides” a form of animal cruelty and banning them in India's financial capital from June 2016.

“Himalayan Dog”. This dog just appeared out of nowhere and followed us for an entire week during our trekking trip in the Himalayan outback. He always used to sleep in front of our tent and guarded us in the nights. When I decided to get up at 4 a.m. to climb the next 5000 m peak for sunrise he accompanied me as well. On the top he was sitting for the entire 30 minutes on this place looking straight into the countryside. Photo location: Ladakh, India.
