Kota has what I love best in dogs: a big smiling face, a waggly tail, very attentive, and a bit of spunk. How adorable!!
And I love how she interacts with your cat.
All I need to do to get mine moving like that is to kneel on the floor and lower my chest to the floor with my arms out. That's the sign of "let's play" in dogs. If you've never tried that with her, you might want to see if she responds to it. It's pretty funny.
