Be carefull with more recently published books about bully breeds. Some of these have directly taken their information from our website (without ever mentioning their source, of course), using terms we have coined (as some neologisms used in the Ca de Bou and Brazilian Bulldog descriptions) and conclusions we have drawn. They have used info that is based on OUR first-hand experience we have collected while we lived in and traveled through some of the countries these dogs are native to, and on our knowledge of the local language, something those authors can not possibly claim. The irony is that they mention the very same selection of bulldog breeds we have featured on this website (while there are more than 30 different bulldog breeds out there, some of which more famous than the ones we have selected for this website), but again we have mentioned only the breeds we have personally checked and researched. Just strange they checked and researched exactly the same list of breeds...
Our suggestion is:
Before you buy a dog breed book check who the author is, if their info is first-hand or just a collection of bits and pieces they reproduced from the internet and previously published books. Of course, research is always based on something that has been done or written before, BUT if it is done seriously sources and references are ALWAYS mentioned. So a good hint is to see if the book has a reference list or bibliography (especially for books published after 2003 or 2004) in which case you can be sure that the author did his own in-depth research and thus wants to show you the path he/she followed instead of just copying and pasting some information from the internet.
Older books (as the three ones mentioned hereafter) do not always have a bibliography, but unlike some of the more recent, coffee table books, the three books mentioned here are classics in their field and stem from real dog authors and authorities who really know their subject !
In case of doubt remember the golden rule: for dog books the older the better, because dog authors of the early times were not as influenced by the internet and influential dog clubs, dog shows and dog breeders. The older the book, the higher the chances the info is based on the author's first-hand experience and is not marketing-oriented. Otherwise the books mentioned on this website are usually all reliable sources.
