One of the first-mentioned written scripts referring to the feeding of dogs was by the ancient Roman poet Virgil in 37 BCE. Dogs are essentially carnivores which is why they have sharp, pointed teeth and short gastrointestinal tracts better suited for the consumption of meat. Dogs have also managed to adapt over thousands of years to survive on meat and non-meat scraps as well as leftovers of human existence which enables them to thrive on a variety of foods. Nutrition for dogs has changed immensely in the last 10 years. It has gone from basically nutritional dog food (dry or wet) to species-specific diets making sure dogs get all the nutrition they need from 'real' food. Here are some suggestions on what best to feed your dogs as well as food and drink that should be avoided as these could be dangerous to your canine friends.
