As humans demand to know what goes into the food they eat, so do they demand to know what goes into the food their four-legged children — their dogs — eat. Dogs are carnivores but, unlike cats, they’re not obligate carnivores. A dog owner shouldn’t be too worried about seeing things such as broccoli on the ingredient label of the can, box or bag of dog food. But what about additives such as preservatives? Should a dog eat only dry food, only wet food, or should they have a mix of both? What is organic dog food? How does puppy food differ from food given to an adult dog? Here are some answers:

Kibble. Kibble is simply a bunch of ingredients, such as meat, vegetables, cereals and fillers that are ground up and turned into pellets. Depending on what’s in it, some pet health experts consider kibble the most nutritious thing a person can feed their dog. Good kibble not only delivers lots of animal protein but cleans the dog’s teeth as it eats. Kibble is also inexpensive, lasts longer than wet dog food and can be bought in great bags that are easy to store in the pantry. On the other hand, some animal nutritionists believe that most kibble is unhealthy because most types of kibble are highly processed. This means they have been stripped of much of their nutrition.
