Dr. Tobin,

Do you have any recommendations for any natural toothpastes or a recipe for one that you like?? I found a recipe that calls for 1 cup of water, 1/2 teaspoon vitamin C powder, and chopped mint. I don't know what's best for his oral health. Most commercial products are loading with chemicals I can barely pronounce. I prefer not to give my dog that. Thanks in advance.
