How many shih tzus are in the world?

It's impossible to know the exact number of Shih Tzus in the world. There's no global registry that tracks every single dog of this breed.

However, we can make some educated guesses:

* Popularity: Shih Tzus are a very popular breed, particularly in countries like the United States, Canada, and the UK.

* Breed Clubs: Breed clubs and registries like the American Kennel Club (AKC) and the Kennel Club (UK) keep records of registered Shih Tzus, but this only represents a portion of the total population.

* Stray Population: Many Shih Tzus are also strays or live with owners who don't register them.

Therefore, the number of Shih Tzus in the world is likely in the millions, but the exact figure is unknown.
