I've had to deal with this also for my Chow. Check out this link, scroll down to read about MD.
Dog Friendly Insurance Companies
I contacted Nationwide once to ask them and at first they said certain dogs were restricted. When pressed as to how they could do that based on the fact that breed discrimination is illegal in MD they first became quiet and then said they would call me back. The next day I received a call that they spoke with their underwriter and were told they had to follow the state law and they would give me coverage. This occurred about 1 year ago so don't know if things have changed. Hope this helps.
Interesting. I've taken the liberty of copying that information to put here so they don't have to follow the link. I have State Farm. I was told that if I have so much as one claim against my dogs, I will be dropped. Period. It still blows my mind that if someone breaks into my house and my dog attacks protecting me, I am liable for damages.
That's just insane. I can't even push the piece of shiat down the stairs, if he falls and breaks his neck, I pay. Laws need to be changed to protect the homeowers.

The Lester Kalmanson Agency Inc. (407-645-5000) specializes in animal-related liability policies.
The Maryland Insurance Department went to Court to strike down dog breed-specific insurance restrictions. Some Maryland insurance companies still try to enforce such restrictions on their Homeowners and Liability policies. Those restrictions are directed at the owners of breeds such as Rottweilers, “pit bulls” and “shepherds”. Any Maryland homeowner receiving a cancellation letter from their insurance company that would exclude insurance coverage based solely on the breed of dog that they own, and if their dog has not bitten anyone, or a claim been filed against their policy, the homeowner should contact the Maryland Insurance Administration immediately at 410-468-2000 or 1-800-492-6116 and file a written protest. Breed discrimination against policy holders by insurance companies is illegal in Maryland.
