Making yogurt is easy, economical and it helps both you and your dog to stay up on your probiotic regimes. With only two ingredients and a few tools, it couldn't be simpler. (While a commercial yogurt maker is convenient, it is not necessary.)
1 qt. milk (low fat or non-fat; cow’s or goat’s milk)
2 or 3 tbsp. of fresh plain yogurt (from the previous batch or store-bought—but be sure it contains a live-culture!)
Step One: Heat the milk
Pour milk into a pot, heat slowly until the temperature reaches 185 degrees, stirring frequently (this can take up to 20 minutes). The longer you maintain this temperature, the thicker the final product. Be sure not to scald or burn the milk.
Step Two: Cool the milk
Pour the hot milk into a bowl or keep it in the pot—it will need to cool down to 110 degrees. You can place the bowl/pot into a larger bowl (or in the sink) with cold water or ice cubes around it to help the cooling. This takes around 15 minutes. It is important that it cools down before adding the culture. High temperatures can destroy the culture.
Step Three: Add the culture
Pour about a cup of the cooled milk into a small bowl or into a two-cup measurer and add 2 to 3 tbsp of yogurt. Whisk. Add it back to the rest of the milk, whisking again to make sure the milk and culture is thoroughly mixed.
Step Four: Incubate
Pour this mixture into yogurt-maker jars or into 2 large glass jars. If using glass jars, cover them and wrap in towels. Place them on a heating pad (set on medium, or a setting that assures 110 degrees) for 8 to 12 hours or until thickened. Or wrap the jars in towels, and place them with other jars filled with hot water into a cooler, close the cooler and let set for 8 to 12 hours. (There are many other methods to provide this low-warmth level, but the key is to hold the mixture undisturbed for 8 hours or more at 110 to 115 degrees.) After the yogurt has set, put in the refrigerator where it will set more. It can keep up to 1 week chilled.
Remember to make your next batch, use 2 tbsp. from the present batch.
There is also an easy crockpot  method you might like to check out, we have heard that it works well.
Extras for Dogs:
Frozen Yogurt Treats:
Your pups will love e a frozen yogurt treat. Pour into silicone ice cube trays, with a few blueberries or other fruit or juice. Dogs eagerly lick up these tasty, healthy treats! Or share your smoothies with them.
Extras for You:
Eat yogurt plain (a French meal favorite) or add honey or an easy-to-make fruit compote like this blueberry one adapted from Anson Mills .
For the blueberry compote:
Place berries into pot with the sugar, salt, lemon juice, and cinnamon stick, and set over medium-low heat. Stir frequently as the berries begin to sizzle softly and melt. They will quickly begin to release their juices and cease sticking. Bring them to a simmer until soft and saucy, about 5 minutes. Transfer to a bowl, remove cinnamon, cover, and refrigerate until ready to use. Stir into a portion into individual yogurt servings.
To use yogurt as a sour cream substitute, thicken it by straining through a coffee filter. Or to make yogurt cheese (dog’s favorite), wrap the yogurt in fine, unbleached cheesecloth and hang it up for a day, for a quick cheese.
