A dog lover, whose female Labrador was 'in heat', agreed to look after, and house, her neighbour's male dog while they were away on vacation.
She had a large house and believed that she could keep them apart, but, as she was drifting off to sleep she heard awful howling and moaning sounds. She rushed downstairs and found the dogs locked together unable to disengage. Unable to separate them and perplexed as to what to do next, despite the late hour 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 his erection and be able to withdraw."
"Do you think that will work?" she asked.
"It just worked for me" he replied
