There are several Insurance Companies that will not insure you if you have any dog that is considered an aggressive dog by the particular Company. There is no fight to be fought, you can't force them to insure you. Find another Insurance Company and don't mention the dog. When you first start a Homeowner's Policy it is not uncommon for them to send somebody out to photograph your house. German Shepherd Dogs bite more people every year than any other breed but any of the branchial breeds scare the dummies.I have Allstate and haven't ever had a problem because of owning serious dogs.If you somehow force this broker (and that is who doesn't want you as a customer) to unwilling insure you, you are inviting regular hefty rate increases.
