https://www.fda.gov/AnimalVeterinary/NewsEvents/CVMUpdates/ucm613305.htm "The U.S. Food and Drug Administration is alerting pet owners and veterinary professionals about reports of canine dilated cardiomyopathy (DCM) in dogs eating certain pet foods containing peas, lentils, other legume seeds, or potatoes as main ingredients. ..Diets in cases reported to the FDA frequently list potatoes or multiple legumes such as peas, lentils, other “pulses” (seeds of legumes), and their protein, starch and fiber derivatives early in the ingredient list, indicating that they are main ingredients. Early reports from the veterinary cardiology community indicate that the dogs consistently ate these foods as their primary source of nutrition for time periods ranging from months to years." Another thing to worry about. I must admit I've never worried about grain-free. Deska happily woofs down horse feed with no apparent side effects. But I just brought 3 bags of a grain free kibble because it was the only one without chicken as an ingredient. Luckily I supplement with home cooked meals, just hope squash (esp pumpkin and zucchini) is ok. Just cut out carrot though - it seems to slow Deska's motility and he gets constipation if he has carrot.
