Upon payment of a ferret, dog or cat license fee, a numbered license tag shall be issued to the owner, which shall bear the name of the County. The license tag shall be securely fastened to each dog's collar or harness, which shall be worn by the dog at all times unless the dog is engaged in supervised hunting, exhibition, or other sport where a collar would endanger the dog's safety or adversely affect its hunting, exhibition, or sport purpose. Any dog not wearing a license tag shall prima facie be deemed to be unlicensed. Under this Subtitle the burden of proof of the fact that such dog has been licensed or is not required to wear a tag shall be on the owner or custodian of the dog. A replacement metal license tag to replace a lost tag shall be issued to the owner of the ferret, dog, or cat upon application to the Department and the payment of a fee of One Dollar ($1.00).
