While gulping water, much air can be transported along with the liquid, making hiccups a common occurrence, especially in puppies. The tongue is covered with taste buds which aid in recognition of flavors. In the cat it is also covered with barb-like structures, very helpful in grooming. The tongue of a dog is also used for cleaning the body as well as communicating with other dogs. The gums in dogs vary greatly in normal coloration or pigmentation.
Most breeds have pink gums.
However, some breeds such as Chow Chows have deep blue-black gums. In some cases, the inner cheeks as well as the tongue are also darkly colored. Inc. All rights reserved.
