Be careful what you feed your dog. Many dog owners are unaware of the dangers! Homemade dog food is becoming a popular option, although hardly a new one, for many dog owners. Every dog alive today can be traced back to dogs who were raised on homemade natural diets. The dog food industry, in comparison to dogs themselves, is young - maybe 50 to 60 years - although canned meat was sold as dog food at the turn of the twentieth century. Originally, the commercial foods were meant to supplement homemade food.
