Question: what kind of dog was fang in get smart

title: Briard
text: This breed is also commonly screened for congenital stationary night blindness ( SNB ) with a DNA test . SNB is inherited through recessive genes . Progressive retinal atrophy PRA , is a disease that causes nerve cells at the back of the eye to degenerate . The condition usually begins in older pets and can lead to blindness . Progressive retinal degeneration or atrophy ( PRD / PRA ) represents a group of inherited eye diseases characterized by abnormal development or premature degeneration of the retina . There are two types of photoreceptors in the retina and these are the light - sensitive rods and cones . They are responsible for detecting light and converting it into an electrical signal that travels to the brain . When the photoreceptor cells deteriorate , vision is lost because the animal has no way to generate an image from the light reaching the retina . Puppies are usually blind before one year of age . For the first time ever , animals ( Briards ) that were born blind gained the ability to see after undergoing gene therapy , according to research from the University of Florida , Cornell University and the University of Pennsylvania . UF researchers had established that the apparently harmless adeno - associated virus can carry healthy copies of a gene into the cells of the retina , which is composed of layers of light - sensitive nerve cells . The healthy gene 's mission : to produce a protein critical to translating light waves into nerve impulses that can be interpreted as images by the brain . The study was successful and the puppies could see in the eye that was treated . Officials from the Foundation Fighting Blindness , which supported the study with grant funds , said the success in reversing blindness in dogs is an important advance .
