How many dog breeds are listed in cynographica britannica 1800?

Unfortunately, there's no way to determine the exact number of dog breeds listed in Cynographia Britannica from 1800 without access to the actual book.

Here's why:

* No central database: There isn't a comprehensive index or database of all dog breeds documented in historical texts.

* Varying definitions: The concept of a "dog breed" has evolved over time. What was considered a distinct breed in 1800 might be grouped differently today.

* Regional focus: The "Cynographia Britannica" likely focused on breeds common in Britain at the time, not a comprehensive list of global breeds.

To find out, you would need:

1. Access the book: Locate a physical copy or a digitized version of the 1800 edition of "Cynographia Britannica."

2. Count the entries: Carefully read through the book, identifying and counting the entries that describe distinct dog breeds.

It's a challenging task, but if you have access to the book, it's possible to find the answer!
