I think we all agree it would be helpful to know what the dog was thinking, and Ruth Tewes shares this insight into canine psychology. Quickly determine which guest is afraid of dogs. Charge across the room, barking loudly and leap playfully on this person. If the human falls down on the floor and starts crying, lick its face and growl gently to show your concern. Always take a big drink from your water dish immediately before licking your human.
Humans prefer clean tongues.
The area directly in front of a door is always reserved for the family dog to sleep. Humans like to be sniffed. It is your duty, as the family dog, to accommodate them. Always sit under the table at dinner, especially when there are guests, so you can clean up any food that falls on the floor. Housebreaking is very important to humans, so break as much of the house as possible.
