Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

The belief that old dogs instinctively run away from home to die is a myth; veterinary science and behavioral studies attribute senior dog wandering or behavioral changes to cognitive dysfunction, confusion, or medical issues rather than an innate end-of-life migration.

The analysis

The claim asserts an instinctual behavior in aging dogs for which there is no scientific basis in veterinary medicine or canine behavioral research. While older dogs may wander due to cognitive decline or disorientation, the idea of an evolutionary instinct to leave home specifically to die is a folklore belief unsupported by any retrieved literature.
