My Electric meter man and my Water meter man always have a big box of dog treats in their trucks and always keep about a dozen in their pockets to keep dogs from threatning them. The last time the Water meter man came was last week Koda was alarmed and kept herself inbetween him and me. I told her to stop growling at the guy and she did. I scratched her behind the ears and she wagged her tail so she knew that she was doing the right thing.
