 It's rare that you need to entice a dog to drink because they usually will naturally want to do so. In the event that you do need to, you can always take a little chicken-flavored broth or beef broth or so forth and put it in the water. Test the broth with the pet first to make sure they like that particular flavor. I've had some where they didn't like beef broth, but they love chicken broth. But you can put a little bit of that in there as well. And if you feel like you really need to, the Pedialy or even Gatorade, but generally they don't care for that. It's usually going to be like something that tastes like their food.
