These signs affix to the doors or windows of any public or private space to warn people of the presence of a guard dog. Even those that don't have a dog within their walls can use the signs as a deterrent for any potential intruder. While the bright yellow background and back font instantly conveys a recognisable hazard sign, these signs also display the warning 'Caution guard dogs on patrol' as well as a picture of a dog for a clear and highly visible message. If your site occupies a large area or you need to protect against expensive equipment, you may want to choose the larger 59 x 42 cm version so that no one could enter your premises without being forewarned of your guard dogs. However, this sign is available in five size choices and three materials (rigid plastic, self-adhesive rigid plastic, and self-adhesive vinyl) so you can find the sign that best meets your needs.
People don't just caution against guard dogs to help protect their property. They also want to warn visitors of the potential risks they could face upon entering an area. The last thing you want as a company is your dog to attack a visitor when you have no warning sign up. Not only is your visitor hurt, but you are the one liable for the attack. If you have a dog guarding your premises, it's always best not to take the risk.
