Humans are capable of complex emotions like love, sadness, despair, jealousy, sympathy, hatred and loyalty. A dogs emotional state is more reactive, instinct driven and survival orientated. Instinct is something which is either there or not there, and it covers survival, maternal, hunting, guarding, pack, and self preservation.
Dogs are living in the present, they react to the immediate smell, sound, and movement.
Logic is alien to humans, all animals have an ability to communicate with each other . Many owners of pets will punish their pet after an event just like a child. Owners will shout and shout, little wonder the little fellow does not want to know. Most owners are apt to forget that dogs are dogs and cannot expect them to behave in a human way, this must distorts the dogs true natural behaviour. Our pets are still wolves in disguise, and still ninety five percent wolf, they will roll in mud, eat faeces, but have many qualities that humans could learn from.
