The Mavericks improved to 4-1 with their third straight win, building a 16-point advantage early in the fourth period before the Raptors put on a late charge. The 5-point final margin was the closest Toronto could come down the stretch.
The quick Dallas start has come without the services of star forward Dirk Nowitzki, who might not return until January after undergoing arthroscopic knee surgery.
The Mavericks, who grabbed just one offensive rebound in a win over Portland on Monday, had 10 of them against the Raptors.
Toronto's offensive load was carried by Andrea Bargnani, who scored 24 points.
