Here is a question/debate on how much you could put something on a visual cue. What if you wore a certain shirt every day to train? Would the dog take that as a cue of "pay attention"? Could "competition" clothes prove to give a better preformance if constantly trained with? Could clothes/toys/enviroments really be conditioned as cues for other behaviors? I got this as a random thought and then really started thinking about it. I personally believe that certain enviroments can be conditioned as a cue for behaviors, and toys could as well (Tennis ball comes out and no command is given, dog sits/ conditioned response). But could clothes? I don't know. I wish I could try an experiment on using certain clothes to condition a cue. What does everybody else think?
