This does not surprise me at all. My Kelsey has more reasoning power than many of those who post here in the political threads.
Kelsey is a 9 year old black lab cross. I also have an 18 year old cat named Rikki. I live in a 4 level backsplit where Rikki has the run of the upper 2 levels. Kelsey has domain over the lower two levels.
Rikki will not venture into Kelsey's area, but Kelsey has no qualms about invading Rikki's territory. Of course, this only happens when the boss (me) is not home.
A while back I noticed that Rikki's food dish would be completely empty and clean. This was strange since she had never cleaned her bowl out so well in the 18 years she has been with me. This happened a couple days in a row and I suspected Kelsey may have something to do with it. Did I mention that I also have a child gate at the bottom of the stairs to ensure that Kelsey remembers where she lives?
One day I left and when I got to the driveway, I remembered that I forgot something in the house. As soon as the key hit the door I heard a scrambling sound. This was, of course, Kelsey hightailing it out of the kitchen down the stairs. When I got to the stairs I found that Kelsey was lying in front of the sofa in the family room. Her favourite spot. She was averting my look and acting like she was surpised and happy at my early return. She obviously had been opening the gate to get upstairs and the gate was always closed when I came home.
She also has a bit of a jealous nature. We have a 7 year old boy and 12 year old girl that live with us. The boy and I will often play and roughouse in the family room. Kelsey gets a look of disgust (if you can imagine that look on a 110 pound black lab cross) and come and position her body between us. Quite often she will give the boy a hip check as she moves through. If we are playing cars or something on the floor, she will come over and plop herself down between us and give out a sound of hhrmmuppph.
I have caught her jumping up to our pear tree to get a pear which she will throw around like a ball until she gets tired of that. Then, she will lay down and eat the "ball". She also picks raspberries from our bush while looking over her shoulder to ensure that she won't get caught.
Dogs are people too.
