Dog Sitter

An elderly lady  agreed to look after and house her neighbours dog. The problem was her own dog was a bitch that was in 'heat'  But she had a large house and she was able to keep the two dogs apart.

She was awakened on the second night by awful howling. She rushed to find them locked together, mating. They continued howling unable to disengage. 

Try as she might she could not part so she reluctantly phoned the vet and a rather grumpy vet answered the phone. 

When he lady explained the problem.the vet said, "I want you to take the phone to the dogs and place it down alongside them.  I will then phone your number back and the noise of the telephone ringing should make the male dog lose his erection and be able to withdraw"

"Oh," said the lady, "Do you think that will work?"

"Well," the vet replied, "IT JUST WORKED ON ME !!!!"
