Another blog I follow, Dog Spies, a fascinating but readable blog about canine behavior written by Julie Hecht, highlighted recently a new book about nutrition and feeding dogs. You can find her original post here. The book is called Dog Food Logic: Making smart decisions for your dog in an age of too many choices. It is written by a nutritionist, Linda Case, who presents unbiased and scientific information about the entirety of feeding including the pet food industry, marketing, nutritional considerations, and more. It is intended for the average owner and reads as such. I have only read parts so far, but can't wait to explore it more fully as it seems to be a complete explanation of what I sometimes try to cover in a 5 minute span with a client.
Also, I have added a few more links to the Nutrition page.
It is very similar to perceived corn allergy in dogs. "I changed to a corn free dog food and now my dog is better, he must have a corn allergy." Corn, as previously discussed, has a very low allergenic rate. There are some dogs that have a true allergy and should avoid corn in their food. Most dogs handle corn just fine. If a dog with a skin condition improved after switching to a corn-free over the counter diet, it is nearly impossible to say whether the dog improved because of the lack of corn, or because of other changes in the food ingredients or composition, or because of environmental factors that also changed, or because the owner's perception of the problem changed.
I just found this an interesting parallel in the current human and animal nutrition climates.
*Gluten, as referred to in celiac or gluten insensitivity, almost always refers to wheat gluten, or rye or barley. Corn has no true gluten; the term corn gluten meal is just a term to refer to the proteins in corn. Therefore, do not confuse corn allergy in dogs, real or imagined, with gluten intolerance.
