Maggie is my one who gets nippy with treats sometimes. So I go back
to saying "easy" before I give it to her & she remembers to take it from my
hand without getting my fingers. If I just stop & say clearly"easy" before
I give the treat, she slows down enough to take it nicely.

I've never taken food from her (no reason) but I can take any chew treat
anytime, usually by trading for something else.
