Walking Otto on Sunday I had an awful experience, a dog kept attacking Otto, it was not with any one and i kept kicking it off but he would not leacve Otto alone, he was trying to mount him for sex, I was terrified, a man saw the distress I was in and caught this dog by the coller untill I could get away, but it ran after us and I went into a garden and closed the gate. The owner came to my help and walked me home with Otto. he said she must be in heat, I said she is a he, what do you make of this?
