I'm trying to train Valentine to use her paw to touch for more than just a split second, but she doesn't seem to understand. I've been using a clicker. If I hold off on giving a click or a treat she just looks at me expectantly, since she's already removed her paw. I've tried holding the marker and her paw, but she just tries to take her paw back. I've also tried luring a treat over the marker, in a sort of hover. That also doesn't work. She taps the marker and looks up at the treat. "There I did it, now can I have my treat?" I'm not sure how to get her to keep her paw on the marker for a longer period of time so that I can reward her for that behavior. I want to be able to have this so that we can use it for tricks like cross paws, etc. Any advice you can give would be greatly appreciated. Thanks.
