My chihuahua won't even move off my chair until I sit on him and he always jumps onto the seat as my ass is coming down. I think he likes being squished.
My dog doesn't say anything and acts like she thinks she's being punished. She obviously isn't, but the poor thing seems to believe she's being punished.
