When I was a kid, my parents knew some folks (in Zambia) who had a swimming pool (as many did). The husband, a young guy, found an Alsatian dog swimming in the pool one day and realized it didn't seem to know how to get out, so he waded in and helped it on its' way. It seemed very agitated, and bit him. A couple of days later, not having thought anything much about the incident, he began to feel unwell, had a fever, headache, etc. and by the fourth day was feeling awful. He went to his doctor and told him what had happened. He was rushed to the hospital for tests by his concerned doctor. Rabies was confirmed, and he was dead ten days after the dog bite.
All dogs, including Africans' hunting dogs, should be inoculated annually. Dogs which were inoculated, when we lived out there, had to wear collars with a differently-coloured and shaped rabies tag every year. Those without tags, or with out-of-date ones, were rounded up by the Police. If they weren't claimed within a week, they were destroyed. It was a draconian system but it kept rabies well down in the urban areas. Unfortunately, many rural areas weren't always reached, and dogs would become infected and pass the sickness on through their saliva to other animals, especially wild dogs and foxes, who then passed it on to other dogs, and so on.
