Start with 2-3 pounds of meat in the slow cooker, beef, chicken, turkey or pork are usually available relatively inexpensively, just make sure you cut them up or use ground options. Stay away from sausage as it has unwanted spices, but you can mix type of meat as you choose. While we often make it with ground beef here, ground turkey or chicken is also usually available and we tend to use what's on sale. For ground beef, we like to use 90/10 beef but 80/20 works fine too. (The number is the percentage of fat, 90% meat, 10% fat and so on).We also will use boneless chicken breasts or thighs cut into cubes and chicken hearts and livers are fine in smaller amounts too. We suggest no more than 1/2 pound of these in a 3 pound mix, they add a lot of fat that can upset a dog's stomach. Using only breast meat, cut up or ground, can lead to a dryer and tougher mix so look for ground turkey and not ground turkey breast. If you want, grind your meat yourself, rabbit, venison and wild boar are good for dogs as well.The recipe says 2-3 pounds, we generally shoot for 2 1/2 pounds but packaging may change that choice. It's not overly critical. We have also thrown in a quarter pound of chopped bacon, though we render the fat out in a skillet first. Bacon grease is a staple around here anyway.
Add the canned beans, a 15 ounce can, Great Northern beans or kidney beans are a good choice. You can use lima beans, fava beans, red beans or black beans too, we just usually have cans of Great Northern or kidney beans in the pantry. Drain the beans and rinse them well before adding them to the slow cooker, we want to remove as much of the sodium these things are packed in as possible.
Add the vegetables into the cooker, we try to use about a pound and a half, 24 ounces, of mixed vegetables. Carrots, peas, zucchini, butternut squash, green beans, spinach and others are fine choices and we usually use the frozen bags for convenience and availability out of season. We do thaw the frozen vegetables first so we don't add all the extra moisture to our mix. Stay away from onions, garlic and other plants in the family though sweet potatoes and fresh pumpkin are great.
This recipe calls for brown rice but you can use white rice as well. In fact, white rice can be a little easier for some dogs. Add 1 1/2 cups directly to the slow cooker. Also add 4 cups, about one package, of a good, low sodium, stock or broth. Chicken, beef, turkey or even vegetable stock are all fins and, if you're short on stock, you can just add 4 cups of water. We figure the broth adds a bit of flavor and some additional nutrients but we basically just need to add moisture to the mix.
Set your slow cooker on low and let it go for about 5-6 hours, stirring occasionally after the first two or three hours. If you're in a hurry, set it to high and go for 3 hours or so. Let the mix cool, then serve to your pets or portion it and store it for later use. You can store in in the refrigerator for two weeks or freeze it for up to six months. Just be sure to label and date it, serving your in-laws dog food when they show up unexpectedly can be embarrassing. Of course, if to don't tell them what it is, it's perfectly good for people, though possibly a little bland.
