Whether your pup isn't eating enough or you're looking to provide a heathy, wholesome treat, broth is an excellent additive to your dog's everyday meal. Store-bought broths contain all kinds of additives, though, ranging from potentially harmful MSG to deadly onions to belly-upsetting sodium. Fortunately, making a healthy broth for your dogs at home only takes a little time, a couple ingredients and is a far healthier alternative to store-bought products.
Place the large pot on the stove but don't add heat. Unpackage the beef bones and place them in the pot. Don't worry about removing fat, gristle, skin or meat just yet.
Add approximately 2 cups of cold water and 2 tablespoons of cider vinegar to the pot. There should be enough water to cover the bones completely but not enough to create a soup effect. Stir the contents for 5 to 10 seconds to mix the vinegar into the solution. Allow the mixture to sit for an hour.
Add medium heat to bring the contents to a boil. Once boiling, reduce heat and allow the mixture to simmer for 12 to 72 hours. The bigger or thicker your beef bones are, the longer your mixture will need to simmer. When the bones are soft and gelatinous, you'll know the broth is finished.
Remove the large chunks of soft bone, meat and fat from the finished broth with tongs. Strain the remaining broth through a colander or sieve to remove all non-liquid parts. The broth can be stored in quart baggies and placed in the refrigerator for five days or frozen in freezer-safe containers for several months.
