My friend lives around the corner from us in Lobatse, which is a small town in south eastern Botswana. She has three much-loved dogs, but she did have five. One day a year ago she phoned me. She was devastated, because her Schnauzer Woopi had died suddenly, from tick bite fever. The next morning I received a completely hysterical call – her Labrador had died overnight at the vet’s surgery in Gaborone, where she had believed he was recovering from a snake bite.
