Okay, it's official all dogs hate the postman - well my dog does!
I have a two year-old black cocker spaniel called Jess who is lovely with not a bad bone in her body but she is very, very vocal. As we live on a front street, she barks at any person, dog, bike, motorbike that goes past and she doesn't stop until she is shouted back into the house. She likes to do her own thing and tends to sometimes ignore you when she is barking.
I always thought that it was just a territory thing but we were nowhere near our house today so it wasn't that today. It must be the uniform too!
