Origin
The son of Thomas Logan. Because of the abuse he endures at the hand of his father, he, too, becomes an abusive, hate-filled person. Originally, he was somewhat a friend to James Howlett and Rose, a girl whom cared for James, when they where young and frail. However, as he ages, Dog became more and more aggressive. After many unanswered sexual commands to Rose, Dog eventually tried to rape Rose, and when that failed, killed James’s pet dog in retaliation. Because of these two incidents, James’ father, John, fires Dog’s father, Thomas Logan.
Angered by his being fired, Thomas Logan, in a drunken fit, breaks into the Howlett’s property with his son. Dog is ordered to shoot James Howlett, but refuses. Thomas kills John Howlett which causes James Jr.’s mutation to kick in. James extends his bone claws for the first time, kills Thomas Logan and severly scars Dog’s face. Rose, not knowing what to do, takes James away, leaving Dog alone. When the police arrive, Dog blames the whole thing on Rose and James.

Wolverine and the X-Men
Dog has since reappeared, alive and well, in the series Wolverine and the X-Men as a teacher at the Hellfire Academy, alongside Sabretooth. He seems to share the same longer life-span as Wolverine and Sabretooth.
Dog and Sabretooth Connection
Based on the most current data, there is no source material that states as canon in the Marvel Universe that Dog is Sabretooth. Despite this, fans on the internet have been inferring or implying the opposite.
An interviewer asked Paul Jenkins if the character Dog Logan was Sabretooth. Paul Jenkins said he had not intended it to be him, but said he wouldn’t have a problem with another writer doing it later. Despite that no writer has yet written a story that Dog is Sabretooth, fans have been spreading unfounded rumors on the internet about Dog and Sabretooth. Sabretooth and Dog have similar characteristics and traits, both are big caucasian males with similar appearances, both enjoy killing, both have grudges against Wolverine, both have abusive fathers, and both possess excellent tracking skills. With no proof, fans are only able to imply or infer their ideas from these supposed similarities.
Recently, the comic X-Men Origins: Sabretooth was released, showing Sabretooth’s own origin. It seems that he and Dog are really two separate characters and any similarities are just coincidental.
Creation
Dog Logan was created by Frank Tieri and Sean Chen and first appeared shadowed in Wolverine issue 166 (2001) and first appeared fully in Origin issue 1, where he was further developed by Paul Jenkins, Joe Quesada and Andy Kubert.
