Do not be mistaken in considering this a purebred. It's studbook is not closed and from a breeding point of view, it is not a breed but rather a cross of some variation of Pit Terrier and some variety of Mastiff. This allows for incredible variations that make it more than difficult to offer any generalities. Additionally, many questions thus arise as to the reason for producing such dogs since they cannot be registered, the best quality animals of the respective breeds would be used to produce purebred (and thus more valuable dogs) so what quality does that leave for producing the Bandogge Mastiff? The emphasis on protection work also means that individuals of a more aggressive nature would likely be selected over those of a more gentle nature. DigitalDog.com finds little to recommend in seeking dogs from this approach.
Trainer notes: These dogs are bred to be powerful and extremely protective. In the hands of anything but the most accomplished trainers (not to be confused with someone who simply works with a good trainer), it is likely that their handling could be too inconsistent, firm yet fair, and with enough focus and time to develop into a reliable family companion. Indeed, it is not produced for that.
