A dog lover, whose dog was a female and 'in heat,' agreed to look after and house her neighbor's male dog while he was away on vacation.
She had a large house and believed that she could keep the dogs apart ...but as she was drifting off to sleep she heard an awful howling and moaning sound. She 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.
Once she 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 his erection and be able to withdraw."
"Do you think that will work?" she asked.
"It did for me" said the vet.
