Frequently Asked Questions

Q. What is the purpose of guard dog signs?

Guard dog signs serve the dual purpose of warning potential intruders against entering your property and giving you some legal protection in the event of the dog harming another person or animal.
Most local regulations also require you to post a notice/warning about the presence of guard dogs on your premises to alert unsuspecting guests and unwanted visitors.

Q. Are guard dog signs effective in keeping intruders away?

Guard dog signs can keep intruders away to a large extent. By declaring the presence of dogs trained to ensure your safety and the security of your property, you send out a clear message that uninvited visitors are not welcome. This tells potential intruders that they run the risk of a serious injury if they trespass or loiter around on your premises.
You can make your signs more effective with the use of strong words and by possibly declaring the dog breed.

Q. How do I decide if I need a guard dog sign or a beware of dog sign?

You should choose a beware of dog sign where you intend to alert visitors and ask them to be careful when visiting. A guard dog sign should be used when you have a guard dog for your safety and the security of your property.
While beware of dog signs communicate the presence of pet dogs on the premises, guard dog signs send across a stronger message about the property being protected by dogs trained to do so. Guard dog signs warn potential intruders that they may get attacked if they trespass.

Q. Do funny guard dog signs really work?

Funny guard dog signs do a better job at attracting attention than simple warning signs and thus, are harder to ignore. Signs that carry quirky warning messages with supporting graphics are likely to grab more eyeballs and send the message out loud and clear.
Our guard dog signs catalog contains humorous options ranging from highlighting a guard dog’s key talents to subtle quips and jibes about the dog owner.

Q. Do you offer breed-specific dog signs?

Yes, we offer a range of breed-specific guard dog and beware of dog signs. Whether you have a lab, a rottweiler, a german shepherd, a Doberman, a golden retriever, or a poodle, pug, Yorkie, or Shih Tzu, we have a sign for you. If you still can’t find one, head on to our custom templates section for dogs; it’s simple from thereon.
Made using waterproof, heavy-duty aluminum, these signs are available in 35 different dog breed images. We offer guard cat signs as well.

Q. Can I customize a guard dog sign with my dog's name?

You certainly can. Our customizable guard dog signs let you design a sign exactly as per your preferences. You can personalize these with your own message that can carry the name of your dog.
You may also choose the header, clipart, and the font style that you want for your sign.
