This is an excellent article that spells out the cost savings and ease of making your own dog food. It gives a recipe and shares some facts about what not to feed dogs. This is good if you are concerned about ingredients in your dog's food, as well as looking to save money while feeding your big dog (or multiple little one's!). You can cook the food once a month and freeze it. The author states that she saves about $30 a month on her one big dog, so if you have multiple dogs, give it a read!
