Snoop Dogg's uncle June Bug passed away Sunday morning after holding on almost a week longer than doctors expected ... and Snoop was the last person to see him.
June Bug's nephew Daz Dillinger tells TMZ ... his uncle died around 9:30 am -- and it happened right after Snoop arrived for a visit.
We're told J.B. happily acknowledged Snoop's presence ... then passed on.
As we previously reported, June Bug was given one day to live last week after succumbing to colon cancer ... but he was clearly a fighter.
