I was really mean to my dogs once.

I cut one of my dogs hair and piled it up on the coffee table.

Then I looked at it and got all excited, I started petting the pile of hair, and stroking it, and talking puppy talk to the pile of hair.
My dogs thought it was another puppy I brought home for them to play with. They got all excited! They got up on their hind legs and danced around!

Then they sniffed the pile of hair… and found out it wasn’t alive.
They then ignored me for the next 2 days.
