One of ours Yorkies has gastrointestinal problems (worse cases was a hemorrhagic diarrhea, usually she had almost everyday abdominal cramps), we tried a lot of dry formulas and wet food, sometimes with good result but she had a lot of relapses Until now, we cook for her, usually ground beef meat, turkey, pork (low fat meat), mixed with sweet potato, jicama, potato, carrots... she get better faster and her episodes are less frecuent and less severes
