We used to call it a "command" when we wanted our dog to offer us a behaviour. I find the parallel with issuing commands to computers very interesting. Do we have unreasonable expectations about our dogs and our training with them? Do we expect unquestioning obedience and compliance from our dogs just the same way we expect our computers and other appliances are supposed to just work? Dogs are not something we can program. They are beings that we need to TEACH!
