A woman's dog came in one day in heat and she was concerned about keeping it and her other dog separated. But she had a large house and believed that she could keep the two apart.
However, as she was drifting off to sleep that night, she heard growling sounds, and rushed downstairs to find the dogs locked together, unable to disengage (as frequently happens when dogs mate).
Unable to separate them, perplexed as to what to do next, and although very late at night, she called her vet.
"Yes?", he answered in a b grumpy voice.
She proceeded to explain the situation to him.
The vet said, "Hang up the phone and place it down alongside the dogs. I'll call you back and the noise of the ringing will make the male lose his erection and withdraw".
"Really, do you think that will work?" she asked.
"Just worked for me."
