Choosing the Right Dog Food

All dog food ads say that they have the best nutrition for your pet.
Is this true?
Some clues from your dog that tells you his food may not be nutritious enough?
Your dog doesn't want to eat the food.

• He's going to the bathroom constantly, has diaherrea continiously or has bad gas.
• His teeth are dirty and brown, has stinky breath or burps constantly.
• He sheds a lot, has a dull coat, has a strong dog smell, gets fleas or worms easily.

Dogs need protein that contains 9-12 of the essential amino acids, carbohydrates, fat, vitamins, minerals, and water.
