I wish that I could find the photos of a cream-colored dog before and after beets were removed from it's diet. There was quite a difference from strawberry-blonde to cream!
Curcumin (the yellow pigment of turmeric plants) has a yellowing effect, by the way.
We don't mind the beets in the Royal Canin 33 because Bodhi is black and tan, so that works perfectly. If he does get more of a silver head, then we'll reevaluate whatever food is for whatever age that may occur.
We aren't concerned about the fat content. Bodhi has gained only 60 ounces in 3 weeks. We've been doing a bit of agility pre-training anyways.
