Some Chihuahuas develop the habit of excessively licking either people or objects such as furniture. While licking is a normal behavioral trait among all dog breeds, it can also be a sign of a deeper issue. Certain health-related problems may be the cause. For instance, the dog may have a dental problem such as bad teeth or gum disease. Because the dog cannot speak, it uses licking as a way of coping with discomfort.
Another health-related cause behind too much licking is obsessive-compulsive disorder. This is a disorder that causes compulsive behavior. The compulsion to lick could be triggered by a hidden psychological issue. The only way to find out for sure if the licking is connected to a persistent health problem is to bring the pet to a trained veterinarian.
If health issues are ruled out, a change of diet may help to reduce the amount of licking.Learn more about Dogs
