What makes dogs go mad?
We think of a dog as mans best friend. Yet sometimes even the friendliest dog can become a creature that brings death with its bite! Not because it has changed its character, but because it has become infected with a terrible disease. This disease is called rabies. It infects the brain and the spinal cord, and these are both vital to life. The infection is caused by a virus; an organism which is too small to be seen with the ordinary microscope. Now we usually think of this disease in connection with dogs, and that is because man most often receives the disease from a dog infected with the virus. But rabies can infect all warm-blooded animals, including wolves, foxes, skunks, cows, cats, and even bats. Most of these other creatures, however, seldom pass on the disease to man.
