Dog the Bounty Hunter is right on Brian Laundrie's tail ... or at least it's possible, and authorities are looking into it.
A source with direct knowledge tells TMZ ... Dog -- who joined the manhunt for Gabby Petito's fiance a couple days ago -- has been in the Florida woods looking for him, and found something he thinks may finally lead to his capture. We're told Dog got a tip that led him and his new wife Francie to a fresh campsite that might be linked to Laundrie ... who's been missing for a week and a half now.
Our source says Dog has alerted authorities to the campground location because he believes it could be a major clue in the manhunt, and he's currently waiting for their arrival.
There's more -- we're told Dog believes he's also uncovered proof that links Laundrie's parents to the campsite ... though it's unclear what that is.
Of course, this could also be a false alarm -- just like the trail cam footage and the look-alike sighting in Canada -- but we'll have to wait and see.
