I guess it sort of looks like a grimace or growling face, but it’s not. She’s smiling. I think it’s funny (and not at all scary) when she does it.
This morning, she wagged her tail so hard that she could barely walk straight. After I said good morning, she stood up on her back feet, smiled and waved her feet at me. This is how she begs for treats.
So I gave her (and Smokey) a few of those bacon-type treats. They love those!
