Dog tongues are long and flexible, which allows them to reach all parts of their bodies. This is helpful for grooming, eating, and cooling off.
Dog tongues are covered in whiskers, which help them sense objects and their surroundings.
Dog tongues are moist and salivary, which helps them to groom themselves and their food. The saliva also contains enzymes that help break down food.
Dog tongues can taste five basic flavors: sweet, sour, salty, bitter, and umami. However, their sense of taste is not as strong as humans.
Dog tongues can help them to regulate their body temperature. When a dog is hot, they will pant, which helps to cool them down.
Dog tongues can also be used to communicate. For example, a dog may lick their lips when they are feeling anxious or stressed.
A dog's tongue can also be a sign of health issues. For example, a dog with a red tongue may have a fever or an infection.
