Ruby
I tested out signallying to Ruby to fetch by just using my eyes. I was surprised by the results. I can use my eyes to suggest something from her as well as using hand gestures or commands.
Visual clues are a big part of how dogs communicate anyway.
I love Ruby~
Dogs that have smarter owners tend to learn more from their owners. Hence, my theory is a dumb dog is often a result of a dumb human. However, there are some dogs that just will not learn.
Ruby looks so much like my own dear “Dutch” from a long, long time ago. I was terrified of dogs, but Dutchie got me over that. Dutch could say “popcorn”.
