Firefighters and Emergency Medical Technicians never know what they’re going to find when responding to emergency calls. Thanks to a donation from Invisible Fence, a company founded in 1973, members of the La Porte City Fire/Rescue Department will travel with three specialized masks for pets. While the local fire department does not specialize in animal revival, the masks, ranging in size from small to large, will allow pets suffering from smoke inhalation to be treated at the scene of a fire.
