My fourteen year old dingo mix, Libby, was on Weruva’s “Bed and Breakfast” and a Blue Buffalo kibble but when I became aware of Blue Buffalo’s legal problems I switched to Hill’s Ideal Balance “Slim and Healthy” because it was recommended by the retailer we use. Libby’s once sleek, shining fur is now dry and dull so I’m looking for recommendations for a kibble that is appropriate for elderly dogs without carb loading. Any info will be greatly appreciated.
