My female is a year and a half old and hasn't had a normal bowel movement since we got her a year ago. She has been to the vet multiple times and been treated for all the basic parasites and intestinal funk. We are being told that she just has a sensitive stomach. Luckily she is otherwise a healthy little girl. We have tried several types of sensitive stomach foods with little to no improvement. Has anyone out there experienced this and found something that helps???
