Of those two, the Wafcol is the better one (actually, it's probably the only decent formula they make). Eukanuba foods usually contain a number of undesirables. Here's a short veterinary article about food allergies and commerical allergy foods: http://netscape.petplace.com/articles/artShow.asp?artID=156&cboArticleContentsNames=14584
I think the Holitique Blendz is a better food than either the wafcol or Eukanuba though. And given that it appears she had a yeast infection, I would definitely cut out the missing link supplement. It's a good supplement, but not suitable for dogs that suffer yeast infections or allergies.
