Animal Ear Protectors (US 4233942)

Tired of cleaning kibble bits out of Fido's ear? This device, developed in the late 70s, provides a way to "protect the ears of long eared animals, especially dogs, from coming into contact with their food or drink while they eat," according to the issued patent. Resembling two plastic paper towel tubes attached to a headgear, the device effectively pigtails each of the dog's ears for complete protection against the onslaught at dinnertime. Just watch out for narrow doorways!
