This unnamed hellhound was owned by the King of Hell Crowley.
Background
History
This hellhound is about five feet in height, reaching nearly its master's shoulder. It has been owned by Crowley since its debut and acts as a pet, bodyguard and assassin.
Season 5
In The Devil You Know, when demons send a hellhound after Brady and Crowley, Crowley decides to bring his own hellhound to fend off the other hellhound while he, Sam, Dean and Brady make their escape. The two hellhounds battle in a vicious scuffle that presumably ends in the other hellhound's death and defeat. Crowley remarks that he is confident in his own pet winning the fight.
Season 6
In Weekend at Bobby's, when Bobby Singer traps Crowley inside a devil's trap in attempt to get the demon to break his contract, this hellhound is brought along just in case, and is used by Crowley as a means to convince Bobby to let him go, or otherwise lose his life. Bobby reluctantly agrees to avoid being killed.
Season 8
In Trial and Error, Crowley sends his hellhound to kill Carl Granville, Margot Cassity and Ellie to collect their souls as part of the deals they made with him ten years ago. Before Sam and Dean can intervene, the hellhound manages to kill Carl and Margot and drag their souls to Hell, but struggles to get to Ellie due to Dean being able to see it using glasses burned with holy fire. Dean attempts to kill the hellhound to complete the first trial, but the hellhound manages to get the upper hand and nearly kills Dean.
Sam disrupts its attack leading the hellhound to attack Sam next, only to be killed by Sam when the hunter slices its belly open with the demon-killing knife. Its blood drenches Sam as per the trial's requirements. Due to its demise, Ellie is spared from her contract.
In Goodbye Stranger, Crowley mentions his desire to get revenge on Sam for killing his poor dog.
