Licking in Dogs

Licking in dogs is a common behavior where the dog uses its tongue to moisten objects, people, or its own skin and fur. This behavior can be normal, but it can also indicate health or psychological problems.

Can Occur with the Following Diseases:

Basics and possible causes

Licking is an instinctive behavior in dogs that can serve several functions. It can be part of grooming, serve to clean wounds, or be a form of communication. Dogs often lick their owners or other dogs to show affection or to get attention.

A common cause of excessive licking is boredom or stress. Dogs that do not receive enough physical or mental stimulation may start to lick themselves to keep busy or to calm down. This can become a habit and, in extreme cases, lead to dermatological problems.

Medical causes of excessive licking can include skin diseases, allergies, or parasite infestations such as fleas and mites. These conditions can cause itching and discomfort, which cause the dog to excessively lick the affected areas.

Pain can also be a trigger for licking. Dogs often lick the area where they feel pain, whether due to injuries, joint problems, or other internal discomfort. Licking can have a soothing effect in these cases.

Another possible reason for excessive licking is a gastrointestinal disorder. Dogs sometimes lick floors or other surfaces when they experience nausea to get relief. This may indicate an underlying gastrointestinal disorder.

Typical accompanying symptoms

Constant licking of certain body parts may indicate skin problems such as allergies or infections. This is often accompanied by redness, hair loss, or skin rashes.
Increased licking of floors or furniture can be an indicator of nausea or gastrointestinal problems. This can be accompanied by vomiting or diarrhea.
Licking of the paws can be due to stress-related behavior or allergic reactions. Redness or swelling on the paws is also often noticeable.
Licking in connection with other behavioral changes such as loss of appetite, lethargy, or weight loss can indicate more serious health problems.
If the licking leads to wounds or ulcers, it is called a lick granuloma, which is often a result of chronic licking.

When to visit the vet?

A visit to the veterinarian is necessary if the licking persists over a longer period of time or is accompanied by other symptoms that indicate health problems. Quick action should be taken, especially if there are signs of pain, infections, or severe behavioral changes.

Even if the licking leads to open wounds or skin ulcers, it is important to see a veterinarian to treat the underlying cause and avoid further complications.

If the dog is licking due to stress or boredom and shows behavioral changes such as aggression or depression, a veterinarian or animal behavior specialist can suggest supportive measures.

Symptom recognition for animal owners and veterinary diagnostic procedures

Pet owners should pay attention to when and how often their dog licks, and whether there are specific triggers or patterns. This information can help the veterinarian make an accurate diagnosis. It is also helpful to keep notes on other accompanying symptoms.

The veterinarian will usually perform a thorough physical examination and may order blood or urine tests to rule out systemic causes. Skin problems can be diagnosed by skin scrapings or biopsies, while gastrointestinal problems may require imaging procedures such as ultrasound.

If behavioral disorders are suspected, a behavioral assessment by a specialist can be useful to identify the exact causes of the licking and develop appropriate therapy approaches.

What can pet owners do and professional therapy options

To reduce licking, the pet owner can first take measures to keep the dog mentally and physically occupied. Regular walks, playtimes, and mental challenges such as puzzle games can help avoid boredom.

If an allergic reaction is suspected, hypoallergenic diets or the elimination of allergens in the dog’s environment can provide relief. Bathing with special shampoos can also be helpful for skin problems.

If pain is the cause, the pet owner should be careful to keep the dog calm and avoid unnecessary stress until veterinary treatment has been provided. Pain relievers should only be administered after consulting with a veterinarian.

In cases of nausea or gastrointestinal problems, veterinary advice regarding an appropriate diet and any necessary medication may be necessary.

Behavioral licking can be reduced through training and positive reinforcement. The pet owner should be careful not to unintentionally reward the behavior and instead promote alternative behaviors.

Outlook on current research

The symptom of excessive licking in dogs has attracted great interest in veterinary medicine because it can indicate a variety of physical and psychological conditions. Recently, research has begun to focus on the neurological and behavioral aspects of this behavior. Studies suggest that licking in some dogs may be associated with neurochemical imbalances, similar to obsessive-compulsive disorders in humans. Researchers are investigating the extent to which neurotransmitters such as serotonin and dopamine may play a role, and whether medications that affect these neurotransmitters can reduce licking behavior.

Another area of research focuses on the genetic predisposition to excessive licking. There is evidence that some dog breeds are more susceptible to this behavior, suggesting that genetic factors may play a role. Long-term studies on various dog breeds are intended to clarify which genetic markers are associated with licking behavior and how this information could be incorporated into breeding decisions. This research aims to reduce the frequency of licking behavior through targeted breeding strategies.

In addition, there are efforts to investigate the influence of environmental factors on licking behavior. Researchers are analyzing how stress, diet, and a dog’s general lifestyle might influence this behavior. It is being explored whether changes in a dog’s environment or daily routine, such as introducing new toys or increasing physical activity, can reduce licking behavior. These studies have the potential to develop simple and non-invasive treatment methods for affected dogs.

Research is also investigating the connection between licking behavior and pain or discomfort. Since dogs cannot communicate verbally, licking is often an indirect indication of physical discomfort. Scientists are working to develop specialized diagnostic tools that can help veterinarians more accurately identify the causes of licking. These technologies could improve the diagnosis of problems such as skin diseases, allergies, or joint pain.

In summary, current research shows that licking behavior in dogs is a complex symptom that is influenced by a combination of genetic, neurological, and environmental factors. The ongoing studies promise to deepen the understanding of this behavior and open up new avenues for prevention and treatment.
