Every dog is different, so don't hesitate to consult your Vet. The first ingredient listed on the dog food packaging is the most used ingredient to make up the entire product. The second one listed is the second most used, and so forth. There is also a section on the percentage of certain elements such as crude protein, crude fat, crude fiber, moisture, etc. It is these two listings that most people use to compare foods.
Some owners are adamant that their dog have only natural ingredients with no animal by-products.
Some owners even cook all their dogs meals while others feed them only raw foods. Before you go to extremes, educate yourself on the various types of dog foods manufactured today, what each ingredient actually does to benefit your dogs' health, and what are the benefits as a whole no matter what the main ingredient may be. Canine nutrition is very different from human nutrition. Here are a few books to get you started. All rights reserved.
