Dobermans are 100% fight to the death to protect you.....
Black labs or any other retriever.
Yes, they are!
Try this for fun.....call your Dobie, pet it good, have him sit....look for a friend across the lawn, kneel next to other dog...point to your friend , whisper in the dog’s ear “watch him”... Oh yes hhee will..you’ll notice as little tension on him....then just whisper “go*”. And watch the fun
