After making sure the owners could not influence their pets’ behavior, researchers tested three groups of dogs. The first 14, representing a variety of breeds, did not watch Guinness. When taught how to use the rod, about 85 percent pushed it with their mouth, confirming that is how dogs naturally like to do things.
The second group of 21 dogs watched Guinness repeatedly push the rod with her paw while holding a ball in her mouth. In that group, most of the dogs — about 80 percent — used their mouth, imitating the action but not the exact method Guinness had used. That suggested the dogs — like the children — decided Guinness was only using her paw because she had no choice.
I agree that the dogs were watching, but why does their reaction suggest a decision that Guinness “had no choice”?
