When it comes to pet nutrition, make sure you include B vitamins in your canine’s diet. They include thiamin, riboflavin, niacin, pantothenic acid, pyridoxine, cobalamin, folic acid, choline, and biotin. Whole grains, liver, vegetables, poultry, and yeast are excellent sources of many of these vitamins. Adding B vitamins to the diet can increase metabolism. Overdosing on certain B vitamins can lead to adverse effects, so if you give your pet any supplements, do it only under the advice of your veterinarian.
