Do dogs ever feel embarrassed?

For those of you who are not aware, I have a 13 year old dog, Tilly.
Here is some background on her current health. Her legs are starting to fail, and sometimes when she comes into the foyer to greet us she falls down.

Tonight when I got home, both of her back legs went out from under her, and she landed on her belly with both hind legs splayed out like a frog. She tried to scoot herself back up but couldn’t so we wound up helping her.

I wonder if at this point in her life, faced with physical limitations, and still trucking on, does Tilly ever feel embarrassed when she falls down, loses her balance, etc? Or is this an anthropomorphic characterization on my part?
