About South Maryland DOG GUARD


Welcome to Dog Guard of South Maryland. My name is Gary Entzian, as the owner and authorized dealer of Dog Guard Out of Sight Fencing, I have been serving Maryland since 2013. I understand that your dog is more than a pet – it is a member of your family. I take pride in the quality and service I offer my customers, and will work with you to customize your pet fencing system to fit the needs of you and your pet.

YOUR DOG deserves the freedom and joy of a yard to run and play in and YOU deserve the peace of mind knowing your dog is safely contained in your yard.
