LadakhWolf-dog hybrids are dissolving an ancient lineage.
India’s Ladakh has 25,000 feral dogs against a few hundred wolves, researchers found; the numeric disparity makes hybridization irreversible without culling.
Dog sterilisation is illegal in Ladakh and Buddhist norms prohibit culling, leaving no policy lever to slow introgression.

AN OLDER LINEAGE THAN THE GREY WOLF
The Himalayan wolf diverged from other grey wolves roughly 700,000 years ago — before the Holarctic wolf radiation that produced every other grey wolf alive today. It is one of the most basal canid lineages on Earth, adapted to hypoxia at altitudes above 4,000 metres through a distinct haemoglobin variant.
THE NUMERIC ASYMMETRY
When one population vastly outnumbers another, hybridization runs only one direction. Every wolf that mates with a dog produces hybrids; every hybrid that mates with another dog dilutes the wolf genome further. The mathematics of introgression are unforgiving when the ratio runs 100-to-1.
THE GENETIC EXTINCTION PROBLEM
A species can go extinct without a single individual dying. If every wolf in Ladakh breeds with dogs for enough generations, the lineage dissolves into a hybrid swarm — phenotypically wolf-like, genetically mongrelized. Conservation biologists call this genomic extinction; the Scottish wildcat and the red wolf are already most of the way there.
WHY FERAL DOGS PROLIFERATE
Free-ranging dogs in South Asia are not strays in the Western sense — they are a self-sustaining commensal population that has lived alongside humans for millennia, surviving on food waste, butcher scraps, and tolerated provisioning. India hosts an estimated 60 million of them, the largest free-ranging dog population in the world.
THE BUDDHIST CONSTRAINT
Ladakhi Buddhism follows the Tibetan tradition's strict reading of ahimsa — non-harming extends to all sentient beings, and killing a dog accrues severe karmic weight. The Animal Birth Control rules under India's Prevention of Cruelty to Animals Act also forbid lethal control nationally; in Ladakh, religious sentiment makes even sterilisation politically fraught. The wolf's defenders and the dogs' defenders share the same moral framework.
THE PRECEDENT
Eastern Europe's wolf populations carry detectable dog ancestry from centuries of overlap; Italy's wolves show 5-10% dog introgression in some regions. Once a small population's allele frequencies tip past a threshold, the original genome cannot be recovered — only managed. Ladakh's window to act is measured in wolf generations, which is to say a decade or two.
