I don’t think doberman qualifies for this list.
These are all words that are tradenames that are used generically. While doberman does come from the originator of the breed, Louis Dobermann, it doesn’t qualify as a generic term.
No one ever calls a dog a doberman generically. At least I’ve never heard it, and I’ve been in the dog game as a handler, trainer, and breeder for forty years. While I do frequently hear retrievers generically referred to as labradors even if they are a golden or a curly-coat (my breed), I’ve never heard doberman used this way.
