Juve got out to a quick start in this match with a attractive long ball from Leonardo Bonucci leading to a ideal volley from Dybala.
This win thus extended Juventus' winning streak to nine matches in this season.
Defender Leonardo Bonucci sent a long ball looping over a flat Young Boys defence and Dybala timed his run perfectly to volley gently past David von Ballmoos. While no longer the centre of attention following Ronaldo's arrival at the Allianz Stadium, the 24-year-old remains a key part of Massimiliano Allegri's squad.
Young Boys bravely went forward but looked vulnerable every time Juventus attacked and Dybala missed a chance to extend their lead by shooting weakly at von Ballmoos.
There should've been a third on the stroke of half-time when Alex Sandro swung a risky ball across the box, but Dybala slipped and Juan Cuadrado completely missed his shot.
"I think this is his best and best goal he has already made for Club Brugge, which was ideal and shows that he is very strong in his head".

LG has included DTS:X 3D Surround Sound, too, and unlike some other flagships out there, the V40 ThinQ has a 3.5mm headphone jack. The new feature is the ability to take a triple Shot which will allow you to create a short video or a GIF with the three images.
It was also Dybala's first hat trick in Turin.
The Argentina global found the net just once in the competition last season as Juventus reached the quarter-finals but has already trebled that tally.
"Of course, I always prefer to play".
"Last year I scored many goals at the start and then slowed down, it was nearly the opposite", he said.
Having won 2-0 at Valencia in their opening Group H game, they are now two points clear of Manchester United, who they face in their next two group games.
Szczesny wasn't asked to do much in this match, but he did save the only shot on target he faced.
