One hot summer day, a blonde tied her dog in the shade of a tree and headed into a restaurant. Twenty minutes later, a policeman entered the restaurant and asked, ‘Who owns the dog tied under that tree outside?’
 
The blonde said it was hers.  ‘Your dog seems to be in heat’ the officer said. 
 
The blonde replied, ‘No way. She’s cool cause she’s tied up under that shade tree.’ 
 
The policeman said, ‘No! You don’t understand. Your dog needs to be bred.’ 
 
‘No way,’ said the blonde. ‘My dog doesn’t need bread. She isn’t hungry ’cause I fed her this morning.’ 
 
The exasperated policeman said, ‘NO! You don’t understand. Your dog wants to have sex!’ 
 
(You have to love this) 
 
The blonde looked at the cop and said,
‘Well, go ahead. I always wanted a police dog!’
