<human>: Background: I have a 3 year old Chow/Shiba mutt rescue who is extremely food motivated and very smart. She's much more interested in the treats than what I want. Sometimes I have to cut training short because she just gets so excited about getting food that she can't sit still. She isn't interested in toys. In the year that I've had her, I've become fairly convinced that she doesn't actually listen to the words I'm saying, just the tone of my voice. She does know her name, but practically all of her commands are hand signals (except for recall (which could still just be tone of voice) and a smoochie noise means come pay attention to me (accidental)). 

The problem: We're on day 3 of training "leave it" and "drop it." Day 1: she got the idea immediately and offered sit in addition to the desired behavior every time. Day 2: after about 6 repetitions she just stopped going for anything I placed or dropped on the ground and offered sit and attention before I could give the command (even when I kept offering higher and higher value treats). Day 3: after 3 repetitions she stopped going for anything on the ground and stopped going for the offered cow ear for drop it. She just sits there and looks at me expectantly wagging her tail. 

I can sometimes get her to go for it if she thinks I can't get my foot between her and it before she can get her mouth around it, but she's usually right, so that's leading to failures.

The treats that I'm offering are her favorite things in the world - chewy salmon and peanut butter flavor training treats, cow ears, and chicken basted rawhides.

Give me the gist of the text in a nutshell
<bot>: trying to train "leave it" and "drop it," but my dog is trying to game the system by not even going for what I'm offering.
