we had a labrador/aussie mix. He would go wild barking at the postman and once got out. She sprayed him with something before he was pulled back inside.If he had gotten to her, he would have jumped on her and tried to hug her, just like he did with any of the utlity people. The post office refused to deliver our mail again until we wrote a letter and moved our box to the curb. Of course, they changed carriers as soon as we did. The new carrier wasn’t so freaked.
Our female Golden Retriever/Black Lab mix barks like crazy when this particular mailman comes to our house. She is always in the house, but the mailman has warned us that he will sue us if the dog hurts him. We make sure she is in the house and the front door is closed.
The mailman is still freaked out whenever he hears her bark. Some people are just scared of any dog.
