What dog is the most famous?

It's impossible to definitively say which dog is the *most* famous, as fame is subjective and depends on factors like:

* Time period: What's popular now may not have been famous in the past.

* Region: A dog famous in one country might not be known elsewhere.

* Type of fame: Is it movie fame, internet fame, or a specific breed's overall popularity?

However, some dogs are consistently considered incredibly famous:

* Lassie: The iconic Collie from the books and movies has been a household name for generations.

* Snoopy: This beloved beagle from the Peanuts comic strip is instantly recognizable.

* Hachiko: The loyal Akita dog who waited for his owner at the train station for years became a symbol of devotion.

* Rin Tin Tin: This German Shepherd was a movie star in the 1920s and 30s, saving Warner Bros. from bankruptcy.

* Buddy: The Golden Retriever from the Air Bud movies became synonymous with canine athleticism.

Ultimately, which dog you consider the "most" famous is a matter of personal preference and what type of fame you value.
