To moisturize a fido's tongue, it is recommended to apply a small amount of olive oil all over its surface. For smaller pups, no more than a 1/4 teaspoon should be used, while larger breeds use up to one tablespoon. Other oils, such as sweet almond oil and CBD oil tinctures, can also be safely used. It is also beneficial to apply a balm to the lips to help seal in moisture. Coconut oil is also an excellent choice for overall skin and coat health.
