GROAN...
My Shepherd mix Abby had a hate hate relationship with the mailman. When she was about 4 months old, she was on her run and the mailman decided she was dangerous because she barked at him. There were nearly 10 feet between the end of her run and the mailbox, but that didn't stop him from emptying a can of HALT in her face. An expensive visit to the vet.
After that, we had to keep her inside as best we could...she broke 4 windows and destroyed a sofa before I discovered the mailman was tapping on the window when he dropped the mail in the box. He denied it, but I saw him. We bought a free-standing mail box and mounted it at the end of the driveway and things calmed down. But, he continued to tease dogs along his route...until the pair of Doberman's discovered the latch was loose on the gate....fortunately the neighbor across the street
videoed the whole thing...the mailman was poking a stick thru the fence and laughing.....
No accounting for some people
