I’m not a “dog person,” but in my line of work one does come across a lot of canine companions. It always brightens my day when a dog I know is sitting at the end of the driveway, and they shove their face into my hand for a pet. They are all, in fact, good dogs.
The only thing is that any dog might one day bite you, no matter how many days in a row you’ve itched their face for them. The dog might’ve had a bad morning, or maybe its hearing starts going and they don’t see you approach.
