That Beware of Dog Sign…What You Need to Know

Beware of Dog Sign

Beware of Dog SignToday I want to talk about that Beware of Dog sign and why it may be more important than you might realize.

First, let me preface this post by stating VERY CLEARLY that I am NOT an attorney. The information in this post has been gathered from various sources and may change at any time. If this information is important to you, I highly recommend doing your own research for your specific circumstance and location.

What You Need to Know About That Beware of Dog Sign

Dog bite law varies depending on the jurisdiction where you live and this is what determines the protection (if any) you receive from posting a beware of dog sign.

The general rule of thumb, however, is that IF someone enters your property understanding that doing so may carry a risk of being injured by your dog, they voluntarily took that risk and this limits your liability as a dog owner for any injury caused to that person by your dog.

How do you prove that the individual entering your property knew that there was a risk of being injured by your dog? You have clearly posted signs at all entry points of your home that advertise your dog’s presence – “Beware of Dog”, “Guard Dog on Duty”, etc.


As I mentioned before, dog bite law varies depending on where you live.

In jurisdictions that have a “dog bite statute” in place, the presence of a beware of dog sign on your property is NOT protection against liability.

Dog Bite Statutes

What’s a “dog bite statute” and what jurisdictions have them?

A “dog bite statute” is a statute that states that IF your dog causes injury to someone – either in a public place or a private place, you ARE liable for that injury EVEN if you did not think that your dog was dangerous or likely to cause injury.

This is referred to as “strict liability statute” because, in order for you to be found liable for the injury caused by your dog, a victim DOES NOT have to prove that you did anything wrong.

For example…

You are walking your dog in the park and your dog has no history of biting someone. A stranger then walks over and engages you in conversation, they reach down to pet your dog, but your dog bites them.

IF you live in a jurisdiction where there is a strict liability statute in place, you will be found liable for your dog biting the stranger EVEN though you didn’t know that your dog was going to bite and they had no history of biting.

It is also worth noting that in some jurisdictions, the injury caused by your dog does not have to be a bite. It may also be another type of injury such as causing someone to fall down the stairs.

So How Do You Know the Law Where You Live?
