How do you know if the food is too hard for digestion? Hannah is currently in the process of changing over to blue buffalo. I read that this was a good food and my trainer suggested it. However, when I feed her all of it (the regular food +the life source bits), she sometimes have traces of blood in her bowels (diarrhea like)-usually the third bowel movement. She acts normal(eats, drinks, and plays). This has happened twicein the last week and only when she ate the life source bits. For the past couple of days I've feed her just the brown parts of the blue buffalo and the remaining parts of her old food ( I am now at 1/4 of old food and 3/4 of new food).
What do you think is the problem. Is it the Blue Buffalo? Could it be something else?
