The same thing happened to me, but because of what she's got, she's become an insanely picky eater.
Her original kibbles would just be left in the bowl. So we switched to wet food. Worked for about a day and a half before she lost interest in that too. Tried softening kibbles with hot water and letting it sit for 20 min before stirring up a bit. That worked for about a week. Then I tried adding peanut butter to that mess which worked for a couple days, then she started refusing that too. Then we switched to giving her "real" food (mixture of chicken, vegetables, and rice) which, again, worked for a couple days before she'd start refusing to eat. So we switched to just straight-up cooked chicken thighs which also worked for nearly a week...
Then she found a pill in a piece of chicken I was hand-feeding her and now refuses to touch any chicken meat, in or out of her bowl.
I'm at my wit's fucking end here. I just want my dog to not starve herself to death and to take her goddamn pills.
