Homeowner’s insurance can refuse to cover an insured for dog bites and other damages done by a pet that lives in the covered household if there is an exclusion in the coverage that applies to damages or injuries caused by dogs or if there is no legal liability for the bite. You need to check your policy’s language to determine whether your policy provides coverage. If it does not and you own a dog that causes another harm, the insurance policy will not cover those damages.
Understanding Liability Under a Homeowner’s Insurance Policy

Why Do Some Homeowners’ Policies Contain Exclusions for Injury by a Dog?
The rates people pay for their insurance are a function of the amount of risk the carrier must take on. The more risk they take on of having to pay claims, the more premiums they charge for the coverage. Each year, insurance carriers pay out over 600 million in claims for injuries caused by dogs. As a result, insurance providers that cover dogs must take into account the anticipated amount of claims they will have to pay. Many providers choose to keep their rates low by not covering dogs at all. Others limit the breeds they will cover to those breeds that are less likely to cause significant harm in the event of an attack. Others will provide coverage for injury and/or damages caused by dogs. However, the rates may be higher to account for the additional risk.
When an insurance company issues a policy, the applicant is required to answer questions about the home occupants, including pets. Because the insurance company has no way of knowing what pets a homeowner may acquire later, the carrier may put an exclusion that applies to any dogs not disclosed at the time of application or they may exclude dogs altogether.
Do I Need to Tell My Homeowner’s Insurance if I Get a Dog After Obtaining a Policy?
Yes. If you acquire a dog, the best way to ensure your dog’s bites are covered under your homeowner’s policy is to call and ask your insurance agent. Then, follow it up in writing so that you document that you disclosed the dog to your agent and requested that coverage be confirmed. Failure to disclose the dog may result in you not learning of an exclusion either in the original contract or added by an addendum later.
How Can I Tell if There Is a Dog Liability Exclusion in My Policy?
If your homeowner’s insurance policy contains a dog liability exclusion, you can find it by looking at your policy under the Liability Insurance section. Usually, towards the end of this section, there will be a list of exclusions. You should carefully read the language of any exclusion that references animals. Dog liability exclusions take many different forms. Some exclude only bites from certain breeds, such as Akita bites, Rottweiler bites, or Presa Canario bites, while others focus on only certain conduct, such as prior bites. Still, some broadly exclude all types of animal claims. Read your policy carefully, and if you are still not sure, discuss it with an attorney who handles dog bite claims.
What Should I Do to Protect Myself if My Policy Excludes Dog Bite Liability?

If There is No Liability Exclusion, Must Homeowner’s Insurance Pay a Dog Bite Claim?
Even if there is no exclusion, under a liability insurance policy, the injured victim must still prove that the dog owner is legally liable. Depending upon what state you are in, you may need to prove negligent handling on the part of the owner, that there has been a prior action demonstrating that the dog is aggressive towards people of which the owner is aware, or you may just need to prove ownership or control. This is because some states impose strict liability for dog bites upon the owner while others enforce the one-bite rule and/or require a showing of negligence.
