First of all, if your dog is allergic to Nutro I highly doubt she's going to get any better with Eukanuba. Both of those foods are notorious for causing allergic reactions in dogs, Euk. being the worst of the two. If you can, I'd try and find something such as California Natural as it is a very simply food (www.naturapet.com has a store locator) and was made for dogs with allergies. You won't find any premium brands in PetsMart. You'll probably have to go to a small petstore. I'm not trying to turn this into a food debate, but am trying to help find a food that will help your Lou Lou with her allergies and the two foods you mentioned are not going to help at all..

As far as muttluks go, I've never used them on my dogs but I've heard from many people that they're really good. Good luck, and I hope you're able to get her allergies under control soon.
