I mostly tell my dog how stinky she is, but yeah. She loves that.
She doesn’t seem amused. But in fairness I have a horrible singing voice.
“Who’s the stupidest one? Is it you? Yes it’s you! You’re the stupidest one! Such a dummy boy!”
This is exactly what I do with my dogs. I had no idea it was a common thing.
Dog: my human acts very foolish sometimes and I am not sure if they even have a single brain cell. Today, they confused me with a drum and sang loudly and out of tune. But they did interact with me that way and I love them in all their goofiness.
