A similar thing that really annoys me is adverts for Presa Canarios that refer to them as Spanish Mastiffs, when in fact they are two separate breeds with the FCI (
Spanish Mastiff and
Presa)
I know I'm probably being a bit picky and in some ways it is an understandable mistake because the Presa is from the Canary Islands and not many people know what a real Spanish Masiff looks like but on the other hand you would expect a serious breeder to be aware of the correct name for their breed!
I first came accross this when I was searching to find out if anyone in the UK breeds Spanish Mastiffs (which they don't as far as I know) so it really annoyed me when I had my hopes up that some one did.
