There are several reasons we might add water to a dog’s food, but the most common reasons would be to add moisture or soften the food. Puppies might not always drink as much as they should to stay healthy, so this is one way to ‘sneak in the good stuff’!
Adding water also makes the whole digestion process in general much easier, from chewing and swallowing to digestion and absorption in the gut. It can even make food smell yummier (to them, at least!) and make mealtimes more enjoyable. As long as you don’t leave the moist food out for too long, it’s usually a risk-free way to mix things up for your pooch.
