Yes, but there is a dog in a cartoon called this.
Blue's Clues Blue Dalmatians
In 1996, a new television educational program for preschool children was launched in the United States, attracting thousands of children in the United States in just one and a half years. Almost 10,000 parents of preschoolers have become its audience, and it actually beat "Sesame Street" in ratings. This is Blue’s Clues, if directly translated, it is “Blue’s Clues”.
Each 30-minute episode of Blue’s Clues has two hosts, Steve and his brother Joe, and the protagonist is an animated dog. The format of each episode is the same: host Steve introduces a puzzle related to the puppy Blue to the young audience. In order to help the children solve the mystery, Blue left a series of clues, all of which have Blue's footprints. In this way, Steve and Blue take the children on a path of exploration, until at the end of each episode, back in Blue's room, Steve sits on the thinking chair and figures out the answer. But that's all, maybe we adults haven't been able to appreciate the uniqueness of this show. In fact, there are many mysteries here.
Blue’Clue is the first children’s television program in the world to introduce interactive concepts, and Dora is the most successful children’s television cartoon in the world so far. The New York Times reported on September 5, 2006: Scientific research has proven that children aged 3-5 who have watched Blue’s Clue have much higher IQs than those who have not! The Blue’s Clue program makes extensive use of interactive factors and truly treats children as part of the program. Therefore, the efficiency of children in receiving various types of knowledge transmitted by the program is greatly improved, and the effect is close to pure interpersonal communication.
