We have one dog with skin troubles, and another who's a picky eater. Brewer's yeast is supposed to be very good for the skin and coat, and we figured we'd add some flavor to entice them to eat their dinner. All ingredients have been cleared by our veterinarian. We've also had good results using Missing Link supplement in place of the brewer's yeast. You can use this to top canned, dry, or homemade food. While some may believe that garlic is harmful to dogs, veterinary nutrition experts are finding that this is not true, and that powder forms of onion and garlic do not contain the same compounds that make their fresh counterparts harmful. If in doubt, ask your vet. Please note that Zaar does not recognize Brewer's Yeast as an ingredient, and that nutrition facts are being calculated without the bulkiest ingredient. The nutrition facts are incorrect.
