Three years after the criminalization of cruelty to animals in Bulgaria, a violator has been convicted. Vidin District Court recently sentenced a 45-year-old defendant to three months in prison for killing a dog in an especially cruel manner. Cruelty to vertebrates is considered a crime as of July 2011, through an amendment in the Bulgarian Penal Code made at the urging of veterinarians and animal rights groups. Although it is considered a crime, police officers often refuse to investigate reports of alleged animal cruelty, especially if the animals are homeless.
