The illustrated book of the dog – Vero Shaw – 1881
If you read the whole paragraph before going to highlighted area you will see that in the last part author say most likely about Presa Canario (Canary Islands are on African cost). Especially knowing description of the first Spanish-Bulldog Toro and than description of Leon (both with cropped ears and names of spanish origin) being of same type we can think that they say more about Presa Canario than an Boerboel (especially that reading this as a whole we can see strong will to get rid of mastiff blood from the old english bulldogs)
