Sahba Barakzai, her family and seven-month-old husky Aseman, tried to get out into the mountains near their home in western Afghanistan every Friday.
But last Friday, the hike turned to tragedy after an unidentified group of men approached the family and shot Sahba's beloved puppy dead.
The attackers told her a woman could not own a dog.
But Sabha fears this may have been something more - that it may have been to do with her teaching girls sport.
"We still don't know about their goal but we think it is because of her career," her sister Setayesh told the BBC. "She was the first woman who has her own club and these things are taboo."
Sahba was used to threats - she had been teaching karate to children in Herat, Afghanistan's third largest city, for 10 years.
She had also set up a cycling club for teenage and young girls - a very public sport in a country where, less than two decades ago, women were banned from going to school, working or even leaving the house without a male chaperone. [BBC] Read more
