There are quite a few good bulldog books available. The Armitage book is a good one to read, so is the Hanna book “The Pit Bull Terrier and His Master” from 1926. And there is the Glass book “The Sporting Bull Terrier” which is on line here –

Frank Rocca wrote 3 books, his most recent is “Fighting for Life” but that book is now getting hard to find. Same with the 2 Bullyson books, they are hard to find and expensive.

The Crenshaw book “My Life and Times with the American Pit Bull Terrier” is worth having too. Of course the 4 Richard Stratton books are classics now. And TL Williams did 4 or 5 books too. Jack’s The Hollingsworth Dogs book is excellent as well.

There are a lot to chose from. The Armitage and Hanna books have been reprinted for some years now but the older reprints are of better printing quality with sharper photos.
