A dog lover, whose dog was a female and in heat, agreed to look after her neighbours' male dog while the neighbours were on vacation.
She had a large house and believed that she could keep the two dogs apart.
However, as she was drifting off to sleep she heard awful howling and moaning sounds, rushed downstairs and found the dogs locked together, in obvious pain and unable to disengage, as so frequently happens when dogs mate.
Unable to separate them, and perplexed as to what to do next, although it was late, she called the vet, who answered in a very grumpy voice. Having explained the problem to him, the vet said,
"Hang up the phone and place it down alongside the dogs. I will then call you back and the noise of the ringing will make the male lose interest and they will become unlocked."
