Your dog isn't just a good dog -- he's your best friend who wouldn't hurt a flea.

But you might have to prove it to get your home insurance company to cover him, especially if he belongs to a breed with a reputation as aggressive.

Home insurers are increasingly cautious about providing liability coverage for dogs because pooches are taking a bigger bite out of their bottom lines.

More than one-third of the dollars home insurance companies pay out for liability claims is for injuries caused by dogs. Last year, dog liability insurance claims cost home insurers more than $483 million, according to the Insurance Information Institute (III) and State Farm, the largest U.S. home insurance provider.

The average cost of a dog liability claim nationwide, which was $27,862 in 2013, has grown more than 45 percent in the last decade, thanks to rising medical costs as well as the size of settlements, judgments and jury awards given to plaintiffs, says Loretta Worters, III vice president.

Traditionally, renters and homeowners insurance has covered dog bite liability legal expenses up to the policy's liability limits. But some insurers now require dog owners to sign liability waivers for dog bites, and some exclude certain breeds of dogs, such as pit bulls, Doberman Pinschers and German Shepherds, from liability coverage, or they charge more to cover certain breeds. Some home insurers won't cover dogs, period.

In some cases, especially if your dog has already bitten someone, you might have to resort to purchasing a separate dog liability insurance policy to cover him.

But in other cases, you might be able to persuade your home insurer to cover your dog if you can document that you are a responsible owner.
