Does anyone have any experience or heard about pet owners feeding lo carb diets to pets?

I just had a horrible experience when I read an article in a natural pet magazine - the journalists claim was that many euthanized pets are combined with other animals found dead and processed back into commerical pet foods. This processing plant was in Canada, but they claim it is a common practice in USA also.

And I thought human food supply was pretty bad - now I am even more disgusted with our "food factories". So I am thinking of switching my dog over to LC - all fresh foods and veggies, no grains etc. Any thoughts?
