An old man had a dog he just loved,
But the dog had the bad habit of attacking anything that moved including people.

His friends told him that if he had the dog fixed he would lose his aggressions and quit this behaviour.

So the old man had his dog fixed and a few days later was in his front room when the mailman came up the steps.

The dog jumped up and went right thru the screen door and attacked the mailman.

The old man ran out and pulled his dog off and began apologizing to the mailman.
