Do you use more than one clicker for more than one dog? I know that some people use the same clicker for different dogs (like Kikopup). But wouldn't it desensitize your dogs to it, on the long run, if you train while the other one is present? Or wouldn't it mark behaviours that are not necessarily the ones you need? For example if you're marking one dog and the other one is just sleeping in another room, or barking, or whatever. I have about six clickers. The Starmark clicker, four i-click clickers, and a Click-r clicker (my personal favorite), and I think I'm not forgetting any else. I imagine they'd learn the difference between different brands, but do you think that they could distinguish between different i-click clickers, for example? They do sound really similar, but a dog's ear is finer. What is your opinion on the subject? What would make the dog less confused? Would using different clickers be worth the trouble?
