Ok just spoke to a food and science nutritionalist at ASPCA. She said she sees no reason why mixing would be bad, because if you are feeding your dog one brand, he/she can just as easily be overdosing on nutrients that way too. That perhaps it will be good to make sure that the vitamin e (IU content) from one food to another is low. The article that I read said you want to make sure the IU for Vitamin E is minimum 50IU for KG and maximum of 1000 IU per kg. So I guess as long as you're staying in the middle it's a good thing. For example my Innova is 300 IU of Vitamin E, and my Nutro is 150 IU per KG. But remember that 1 KG is 2.2 lbs, so since our babies are so small I doubt any of them eat 2 lbs worth of kibble. They probably eat between 1/3 to 1/2 cup of dry kibble a day. I will still talk to my vet to make sure but we can all rest assure that we are probably not overdosing our babies. |
