Do you think it's possible to teach a dog answers as opposed to just commands? I think it is. You can teach a dog to sit when you tell it to sit. You can teach a dog to roll over, lay down, come, fetch, etc. My theory is that dogs know what they want. There has got to be a way to teach them to communicate that. If a dog wants something it will usually come up to you and either just sit there, whine, or maybe bark. But what does it want? Does it want to play, eat, go outside, or does it need to show you something? Who knows. All you can do is sit there and ask it "What do you want?" like an idiot (by idiot I mean you, the one expecting the dog to actually tell you what it wants). Here's my theory. I think it's possible to teach a dog to respond to words based on if it wants to do a specific thing. For example. If it's possible to teach a dog to respond to very simple questions the following scenario could actually play out: Dog walks up to you and acts nervous or whines. Obviously it wants something. You could say to it "Outside?" The dog doesn't want to go out side so it lays down and puts its hands over it's head. (or whatever you think would be the best thing to teach it to do to communicate "no".) You give it another option, "Food?" Food was in fact what the dog wanted. The dog stands up and barks when you say "Food". This means "yes". Do you think something like that could be taught to a dog? I think it could. With some of the dogs I've seen in movies and on talk shows I know dogs can be very intelligent if given the right opportunity. Do, do you think it's possible to teach a dog to respond differently to simple questions based on what it wants?
