A dog was stabbed to death in Central Park Saturday after its owners got into an argument with another dog walker, police said.

The suspect was walking two dogs near 106th Street and East Drive around 8:30 p.m. when he became entangled in a verbal dispute with a couple that was walking their own two pets, according to the NYPD.

The man pulled out a knife and savagely stabbed Eli, a pit bull-German shepherd mix, before fleeing on foot.

The owner, 43, told cops her husband rushed the critically injured dog to an area animal clinic, where he was euthanized.

The assailant — whom the couple said was not known to them — is still on the lam.
