Can insurers put underwriting conditions on the issuance of a policy for specific dog breeds?

An insurer may impose underwriting criteria related to the possession of any dog, but not based on a specific breed of a dog.  An insurer may impose underwriting criteria unrelated to the breed of the dog. For example, it will insure homes with a dog greater than 40 pounds only if they have a 6-foot fence.
