The next important attempt to classify dogs was made by Buffon (
1707 - 1788). He drew up a genealogical tree of all the known breeds
of dogs which he indicated were all descended from the Shepherd
dog.
1. Bulldog. 2. Iceland Hound. 3. Wolf Dog.
4. Terrier.
5. Large Spaniel.
6. Small Spaniel.
7. Lapland Dog.
8. Shepherd Dog.
9. Hound.

12. Harrier.
13. Water Dog.
14. Mastiff.
15. Large Danish Dog.
16. Irish Greyhound.
17. English Greyhound.
18. Large Greyhound.
19. Great Hound Mongrel
In 1791 the Dublin edition of the Encyclopaedia
Britannica based its five main classes on Buffon i.e.
Sheepdogs, Hounds, Spaniels, Greyhounds and Bulldogs.
