No dog will starve

She has you trained well... she doesn't touch her food, looks up at you, you give her a treat. She figures, this is great! So all I have to do is not touch my food and this lady gives me something better.... lol
If she doesn't touch it, just let it sit for a few minutes. If she doesn't start eating after 15 minutes, pick it up for a while. Then you can put it back down. She will figure out if she's hungry- she'll eat.
Don't get me wrong, I like to find a food that Jackson loves taste-wise too but there comes a point where you just have to stop letting them be so picky. I do rotate foods after each bag is done to keep it interesting!
