tucked tail with kong toy?
I just got Butterbean a classic kong toy (the small one for average chewers, appropriately for her size and activity level). When I put treats in it, she's very intent on getting them out. She looks like she's enjoying herself except for one thing--she tucks her tail between her legs, sometimes so much that the tip is flat against her belly. I've always thought tail up = happy/confident and tail down = scared/upset. Does this sound like the kong toy is making her nervous in such a negative way that I should discontinue its use, or am I misreading the body language of her tail position?
