Just went through this the past week with Soph. We did go to the vet to rule out parasites (negative). Finally decided it was a new treat that upset her system. Luckily it wasn't both of them, just her. Week of boiled chicken and rice and we have good poops again. One thing i do is boil the chicken first and then use the broth from that to fix the rice. Soph seems to like it that way instead of just plain rice. Then I run the chicken through the food processor and mix in the rice so she doesn't just pick out the chicken like she would if it was chunkier. if she would eat it I would have given her a couple teaspoons/day of pumpkin too but little miss picky pants doesn't do veggies
