Dear X: There is nothing toxic or harmful in dog food; and I note that you say tendency. As a snack/treat - it is far better than much of the stuff we normally see ferrets get - raisins, cheerios, etc. However, the problem is when it becomes more than a treat and becomes the staple of the ferret's diet. Ferrets have markedly different nutritional requirements than dogs, and a requirement for compounds that are not present in dog food, like taurine. I daresay that if you started eating the dog's food as well, after while, you would have some nutritional deficits! But if you would like to eat it as an occasional treat - it certainly won't hurt you. With kindest regards, Bruce Williams, DVM [Posted in FML issue 3623]
