Many programmers have heard of the phrase yak shaving. In real life, do yaks literally get shaved?
This answer to a question about shaving dogs has someone claiming that yaks do get shaved:
Whatever you call it, removing the hair from a yak can be hazardous to your health!

Rare, but not non-existent ... :-)
A page talking about yak wool seems to suggest they don't literally get shaved:
Mongolian yak live at high altitudes and endure harsh winter conditions. This means they produce a robust and unique wool that can be as soft as cashmere, warmer than merino wool, odour-resistant, breathable and less prone to pilling and fluffing than other woollen fibres. This precious wool can be sourced only by hand-combing each yak individually, once a year, when the yak shed their winter coats.
Do yaks literally get shaved, especially if living in their normal environment?
