An Idaho city has placed new restrictions on the owners of dangerous pets.

The Idaho State Journal reports that under Pocatello's new rules, which take effect in February, any animal found to be dangerous by the courts must be registered with the Animal Services Department.

The registration requires rabies vaccinations, proof the animal was spayed or neutered and visible signage warning of a dangerous animal on the property.

Owners must also keep the animal in a proper outside enclosure and muzzled in a fenced yard until the enclosure is constructed.

Portneuf Animal Welfare Society President Jo Lynn Anderson says she agrees with the ordinance but is concerned about the well-being of muzzled dogs. She says it could be fatal if the dog can't open its mouth to breathe on a hot day.
