It was only when she started taking walks outside at about three months old that we noticed peculiarities in her behaviour. We took Molly to the vet to get it looked at. After examining her, the vet said: “I’m going to have a senior colleague look at this,” and took Molly into a back room. But she said: “No, it means Molly has male and female genitalia.” I was flabbergasted; I had never heard anything like it. In the meantime, Molly started to behave more like a male dog, mounting cushions and soft toys, although this often left her sore and unhappy.
