Polli is my PITA eater and with the chemo it's horrible.
For Polli- it's carbs- crunchy carbs- much like a pregnant woman who has morning sickness can eat crackers for nausea.
So, try cracker with peanut butter, granola bars (nature valley peanut butter) burpdog biscuits, peanut butter dog cookies, milkbones and if we were really lucky, she would eat shredded chicken breast very late at night. Keep the greasy stuff away from her.
