"Say thank you!", "Take your hand off your mouth when you speak!", "Don't play with your food!" - from childhood we humans are told what is polite and what is less appropriate. "Thank you" and "Please" are the first words you learn in a foreign language, because communication is the secret to making living together work. But only if everyone involved speaks the same language. This is true not only for different cultures, but also for different species such as humans and dogs. This is where Masih Samin's work comes in. The dog behavior therapist successfully works as an interpreter between humans and dogs and teaches us to understand the language of dogs and thus to translate our world and our culture to them. For this purpose, the differences and similarities in the communication of humans and dogs are illuminated and appeasement signals as innate.
