Nickelodeon is expanding its preschool roster with “Mutt & Stuff,” a live-action preschool series created by TV legends Sid and Marty Krofft, and Bradley Zweig.

Set in a unique school for dogs, the series stars Calvin Millan and his dad, Cesar, star of “Cesar 911” and “Dog Whisperer with Cesar Millan,” interacting with a cast of both real dogs and puppets at a canine school called Mutt & Stuff.

“Mutt & Stuff” will premiere July 10. Cesar Millan also serves as executive producer.

“‘Mutt & Stuff’ will capture the hearts and imaginations of preschoolers everywhere with its upbeat energy, heartwarming friendships and valuable lessons," says Russell Hicks, president, content development and production, Nickelodeon Group. "Sid and Marty Krofft have been entertaining kids for decades with shows that expertly blend fantasy and reality, and ‘Mutt & Stuff’ truly embodies their colorful signature style."

Nickelodeon's award-winning NickJr.com and the Nick Jr. App will feature "Mutt & Stuff" content including episodic clips, series trailer and theme song. The series premiere of "Mutt & Stuff" will be available on NickJr.com, the Nick Jr. App, Nick VOD and DTO beginning July 11.
