1. My dog loves to chase her ball.

This gizmo would be perfect for her! Although she’s not too good at dropping the ball once she gets it.

Very clever machine and clever dog!

2. That's adorable.

Just think if he can get a few of his buddies to play along. They need to be all Democrats, because Republicans will take the ball & run with it.

4. That's sad.

No doggie should play by itself.

6. there is obviously someone there videoing it

and probably encouraging it. plus what is wrong with a dog playing alone? they do it all the time, just leave a puppy inside and go away for a while

7. This is using a tool and understanding cause and effect.

Smart doggo.
