Sure, your pets might not be picky. Your dog might even enjoy a delicacy out or your cat’s litter box. But their health depends on what they eat, and knowing a few basic facts can help you make the best picks out of the hundreds of choices of pet food.

In general, research tells pet owners to avoid corn, wheat, soy and by-products. “I’ll ask them to find the ingredient panel on a bag of pet food and see if the first five ingredients are of good quality.  You are looking for quality proteins, not fillers.”

This is where price can be misleading. A pet food may cost more, but it might balance out because your pet might need less of a higher-quality food to meet its nutritional needs.
