Sara, i wonder if this video might be helpful to Mouse? to help Mouse shift her att'n off of the food? Probably you HAVE already done these exercises, sorry if i am posting an idea you already tried. I just can imagine, how when one is dealing with a dog who has limited input from other senses, that such a dog like Mouse, might be ESPECIALLY challenging to help with food obsession, since that is a sense that Mouse CAN fully enjoy, and possibly, Mouse might have less other stimulus (things heard, things seen) to compete against taste being NumberOne piece of her mind who knows, but, i can imagine, how it might be so so much harder for Mouse to find a way to find anything else to focus on besides food sometimes. Buddy is also very food obsessed, and i had to train him "leave it" pretty early on, to help him focus in the presence of food, to help him break his laser-like 500% focus on the food. besides this video below, just teaching Mouse a plain "leave it" cue, (google kikopup "leave it" to see her vid on that) who knows, even teaching Mouse the "leave it" concept, *might* be helpful to Mouse to develop even more self control/new ability to focus on other stuff in the presence of food, etc etc. who knows?
