Nope, dogs don't; they don't leave us hanging. On the other hand, we humans are horrible for leaving our dogs and other humans hanging. One of my biggest pet peeves of all time is when you communicate with someone and they leave you hanging. Honestly, it drives me crazy. Whether it is asking a question, responding to a request, scheduling an appointment or whatever, REPLY!!!!!! Dealing with companies and individuals who leave me hanging got me to thinking about our dogs, of course.
Dogs never leave us hanging; there is always a response. Sure, it may not be the response that you want; but it is a response. It always makes me laugh when I see someone who has been flipped off by their dog and doesn't understand. "He must not have heard me," or "he doesn't understand" they exclaim. No, he heard you and he understands; he clearly told you that he is not complying and has a completely different agenda than you. Dogs will always respond, it is yet another wonderful thing about dogs. Even if the response is going to be negative; they'll give it to you.
Leaving our dogs hanging after we ask them for a specific behavior is a failure in the canine/human communication spectrum. Even the most minute requests should be followed up with feedback. Some sort of communication should be given in response to a behavior. If you don't like something that your dog is doing, tell them. If you love something that your dog is doing, tell them. When we communicate with our dogs; we have the option of communicate using body language, use that too. Feedback does not always have to be vocal or verbal with dogs.
Humans? No, humans are nowhere near as good at responding as dogs are. Like dogs, we are all different; some people are much more gifted in the communication department than others. But the absence of the very basic communication requirement of a response is a little hard to handle. When individuals ignore a response; it is downright rude. When a company or business does not respond; it is highly unprofessional. Purposely not responding speaks volume about you and your company.
If we humans could just learn to communicate from our dogs; wouldn't that be a wonderful thing?
