its not something a dog needs my any means.I just don't see how crisco is good for a dog..it is the proccessing of the oil that cause the trans fat..no good for you, no good for your dog..personally I feel that way about any rendered grease, lard, tallow.....eggs good, grease/vegetable shortening bad!
i would like to know that answer too.I am not disagreeing that fat is good for a dog I just question the nature of that fat. In my opinon rendered fat is not the best...raw fat on the other hand I see no problem with it. This article didn't really explain what makes a fat high quality or not. Anyway my dog gets little carbohydrate or veggies. He is very healthy but, that maybe his genetics for all I know.
