By law, dogs and cats over 4 months of age must wear current rabies and pet license tags. It can save your pet's life. An immediately visible license tag on your pet's collar is the fastest way to be reunited with your lost pet and is only issued with proof of regular vaccination against the deadly rabies virus. The rabies tag issued by your veterinarian is NOT your County license!
If you own a dog or cat 4 months of age or older you are required by law to have both a valid rabies vaccination and a Montgomery County Pet License. These laws apply even if your pet is confined on private property.
