Non-urgent see a veterinarian within 2–3 days
ORANGE for acute Swelling, severe pain, redness/heat, Fever/apathy, or if the dog cannot bear weight on the hind leg; RED for severe general deterioration or suspected acute torsion/trauma.

Definition
Licking of the scrotum in dogs is a behavior in which a dog repeatedly uses its tongue to lick the area of its scrotum. This behavior may indicate discomfort, itching, or pain and often requires a closer examination to identify the underlying cause.
Can Occur with the Following Diseases:
Basics and possible causes
Licking of the scrotum in dogs can be caused by a wide range of factors, from minor irritation to serious medical conditions. In many cases, licking is a response to itching or pain in the scrotal area. Dogs use licking as a way to relieve discomfort, similar to how people scratch when something itches.
One of the most common causes of this behavior is an allergic reaction. Dogs can react to various allergens, including environmental allergens such as pollen, house dust mites, or certain chemicals. Food allergies can also show up as skin irritation, prompting the dog to lick the affected area.
Another possible cause is an infection. Bacterial or fungal infections can develop in the scrotal area and lead to inflammatory conditions and itching. Such infections can be promoted by injuries, a weakened immune system, or poor hygiene.
Parasite infestation, especially fleas or mites, can also trigger intense licking. The parasites cause itching and discomfort, which prompts the dog to soothe the affected area by licking.
In some cases, licking may be due to behavioral problems. Stress, boredom, or anxiety can cause a dog to self-soothe by licking excessively. This behavior can become entrenched and develop into a chronic problem that persists independently of physical causes.
Typical accompanying symptoms
- Skin redness: Redness of the skin on the testicles can be a sign of inflammation or irritation.
- Swelling: Swelling in the scrotal area may indicate an infection or injury.
- Skin lesions: Open wounds or scratches can result from constant licking and become infected.
- Unpleasant odor: A foul or unpleasant smell may indicate a bacterial infection.
- Behavioral changes: The dog may appear restless, scratch frequently, or generally appear uncomfortable.
- Loss of appetite: In some cases, the discomfort can be so severe that the dog loses interest in food.
- Increased drinking: Increased water intake may indicate systemic problems that may be related to the skin problem.
When to see a vet?
A visit to the veterinarian is urgently advised if licking of the scrotum is accompanied by additional symptoms such as severe redness, swelling, or bleeding. A veterinarian should also be consulted if the dog shows signs of pain, such as yelping when the area is touched.
If the behavior occurs suddenly with no obvious reason or does not improve despite at-home care, veterinary advice is needed. A veterinarian can ensure there are no serious medical conditions that require specific treatment.
In the event of signs of systemic diseases, such as fever, lethargy or weight loss, a veterinarian should also be consulted immediately to rule out possible serious diseases.
Symptom recognition for the pet owner and veterinary diagnostic procedure
Pet owners should pay close attention to their dog’s Behavioral changes. Sudden or increased licking of the scrotum can be an early sign of a problem. Noting whether the dog also shows other symptoms can be helpful for diagnosis.
The veterinarian will first take a thorough medical history to identify possible triggers. Questions about changes in the dog’s environment, diet, or recent activities can provide clues about potential causes.
A physical examination of the scrotum can reveal signs of inflammatory conditions, injuries, or infection. The veterinarian may also take a skin sample or swab to test for bacteria or fungi.
If allergies are suspected, blood tests or intradermal skin tests may be performed to identify specific allergens. An elimination diet plan can also help determine food allergies.
If a behavioral cause is suspected, the veterinarian can make recommendations for behavioral modification or consult a specialist in animal behavior.
What the pet owner can do and professional therapy options
Pet owners can take some measures to relieve their dog until veterinary treatment is available. Using a gentle, hypoallergenic shampoo can help soothe skin irritation and keep the skin clean.
Putting on a protective collar (also known as a “cone”) can prevent the dog from continuing to lick the area and worsening potential injuries or infections.
Keeping the dog in a clean, stress-free environment can also be helpful. Reducing stress through regular exercise and mental stimulation can lessen behavioral problems.
If an allergic reaction is suspected, removing potential allergens from the dog’s environment may provide temporary relief. This can include avoiding certain food ingredients or minimizing contact with known environmental allergens.
If a vet visit is necessary, all observations and measures taken so far should be noted and shared with the veterinarian to facilitate diagnosis and treatment.
Outlook on current research
Current research in veterinary medicine is investigating the psychological and physical causes of licking of the scrotum in dogs. It is increasingly recognized that this behavior is not only due to physical discomfort such as itching or pain, but may also have a psychological component. Stress, boredom, or anxiety can trigger behaviors such as excessive licking. Researchers are working to better understand these behavior patterns and develop effective treatment strategies.
Another line of research is examining the role of allergies and skin diseases as triggers for licking of the scrotum. Studies show that dogs suffering from allergies or certain skin diseases tend to lick excessively more often. These findings have led to the development of specialized diets and treatment plans aimed at relieving such conditions and reducing the behavior.
In the field of neurology, the neural activity of dogs that show this behavior is being studied more closely. Researchers are analyzing whether there are specific neurological patterns associated with licking of the scrotum. Early results suggest that some dogs have neural dysfunctions that may affect behavior. This could lead to new approaches to diagnosis and treatment.
In addition, genetics is being explored as a possible factor. There is evidence that certain breeds may be genetically predisposed to show this behavior. Genetic studies have begun identifying specific genes associated with excessive licking. The aim of this research is to develop breeding programs in the long term that minimize the risk of such behaviors.
The role of hormones is also being investigated more closely. Hormonal fluctuations, especially in intact male dogs, can influence licking of the scrotum. Studies show that castration / neutering can reduce the behavior in some cases, although this is not universal. Researchers are working to better understand the exact hormonal mechanisms and develop alternative treatment options that are less invasive.
Overall, research in this area is diverse and interdisciplinary. It includes aspects of behavioral biology, dermatology, neurology, genetics, and endocrinology. This comprehensive approach aims to deepen understanding of licking of the scrotum and develop effective treatment strategies tailored to each dog.
