When to visit the vet?
Non-urgent see a veterinarian within 2–3 days
ORANGE for severe pain, swelling/heat, blood/pus, fever/apathy, or if the dog does not want to sit down; RED for signs of circulatory issues or severe blood loss.

Definition
Increased perianal licking in dogs is a common behavior that can indicate various underlying problems. It is a behavior in which the dog continuously or repeatedly licks its anal area, indicating discomfort or irritation.
Can Occur with the Following Diseases:
- Narrowing of the anus and rectum in dogs (anal stenosis)
- Anal Saccul Inflammation in Dogs (Anal Sacculitis)
- Intestinal infection with the pumpkin seed tapeworm/cucumber seed tapeworm in dogs (parasitic intestinal infection with Dipylidium caninum)
- Inflammatory Connections Between Rectum and Outer Skin in Dogs (Perianal Fistula)
- Rectal Prolapse in Dogs (Rectal Prolapse)
Basics and possible causes
Dogs lick their anal area for various reasons, ranging from simple behaviors to complex medical issues. One of the most common causes is the presence of anal gland problems. The anal glands, located on both sides of the anus, can become blocked or infected, leading to pain and itching. This prompts the dog to lick the area to find relief.
Parasites, especially worms like tapeworms, are another common cause. These parasites can live in the dog’s intestinal tract and irritate the anal area, causing the dog to lick this region. Flea bites can also lead to itching and irritation, causing increased licking.
Allergies, whether to food or environmental factors, can also be a cause of licking in the anal area. Allergic reactions often lead to skin irritation and itching, which prompts the dog to lick itself. Furthermore, skin infections caused by bacteria or fungi can also lead to this behavior.
Finally, licking can also be attributed to behavioral problems such as stress or boredom. Some dogs show compulsive licking as a coping mechanism in stressful situations or when they are not sufficiently mentally or physically challenged.
Typical accompanying symptoms
- Increased licking of the anal area: Dogs suffering from anal area problems tend to lick this area more often than usual.
- Scooting their bottom across the floor: This behavior, also known as “sledding”, indicates itching or irritation.
- Redness or swelling around the anus: Visible inflammation can indicate an infection or an allergic reaction.
- Unpleasant odor: Infections or problems with the anal glands often lead to a strong, unpleasant smell.
- Swollen or blocked anal glands: Examination of the anus may reveal swollen glands, indicating a blockage or infection.
- Changes in bowel movements: Diarrhea or constipation can also be associated with anal problems.
- General restlessness or behavioral changes: Dogs may appear restless or irritable if they are suffering from anal discomfort.
When to visit the vet?
A visit to the vet is advisable if the perianal licking lasts longer than a few days or intensifies. It is particularly important to see a vet if the dog shows signs of pain, the area around the anus is very red or swollen, or if an unusual odor is noticeable.
If other symptoms such as loss of appetite, lethargy, or fever occur in addition, rapid action is also necessary. This could indicate more serious health problems that require immediate veterinary care.
A vet should also be consulted if the dog shows signs of parasites like worms in the stool or if you notice the dog frequently scooting its rear across the floor, to determine the exact cause and initiate appropriate treatment.
Symptom recognition for animal owners and veterinary diagnostic procedures
It is important for the pet owner to observe the dog’s behavior closely and, if necessary, take notes on the frequency and intensity of the licking as well as other symptoms. This can help the veterinarian with the diagnosis. The vet will usually perform a thorough physical examination to check the anus and anal glands for signs of infection, swelling, or other abnormalities.
Additionally, the vet may order a stool sample to determine the presence of parasites. If allergies or skin infections are suspected, further tests such as blood work or skin swabs may be required. In some cases, an ultrasound of the anal glands may also be performed to diagnose a blockage or an abscess.
Together with the owner’s observations and the test results, the vet can make an accurate diagnosis and develop a therapy plan tailored to the dog’s specific needs.
What can pet owners do and professional therapy options
As a first step, the pet owner can try to gently clean the dog’s anal area with a damp cloth to relieve superficial irritation. It is important to ensure that no aggressive cleaning agents are used so as not to additionally irritate the sensitive skin in the anal area.
The pet owner should also ensure that the dog is dewormed regularly to avoid parasitic infections. A balanced diet can also help reduce the risk of allergies and support the dog’s overall health.
If allergies are suspected, an elimination diet under the guidance of a vet can help identify possible triggers. Regular exercise and mental stimulation can also help reduce behavioral changes like stress or boredom that can lead to compulsive licking.
If the licking persists or worsens despite these measures, it is crucial to seek the advice of a veterinarian to ensure appropriate treatment and to ensure the dog’s well-being.
Outlook on current research
Current research is intensively investigating why dogs show increased perianal licking, as this is a common symptom in many diseases and ailments. One focus is on the analysis of the gut microbiota and its influence on dog behavior. Researchers are particularly interested in the role of the intestinal flora / gut microbiota in modulating inflammatory conditions and how these influence dog behavior, especially regarding licking. Studies suggest that an imbalance in the intestinal flora can promote systemic inflammatory conditions, which in turn can lead to itching and other skin irritations that trigger licking.
Another area of research focuses on the neurobiological aspects of licking behavior. Scientists are investigating how neurochemical changes, such as an imbalance in neurotransmitters like serotonin and dopamine, influence behavior. These studies are important to determine if behavioral disorders like compulsive behavior play a role when dogs excessively lick their anal area. The results could lead to new treatment approaches aimed at regulating these neurotransmitters.
In addition, the genetic predisposition of dogs is being investigated, which could influence licking behavior. Genetic studies have begun to identify certain breeds that are more susceptible to behavioral problems that include licking. By understanding the genetic factors, researchers hope to develop preventive measures that can be used specifically in particularly susceptible breeds.
Behavioral research is also investigating the extent to which stress and environmental factors influence licking behavior. Researchers have found that dogs living in stressful environments or receiving little mental and physical stimulation more frequently show problematic licking behavior. Studies aim to develop best practices for enrichment and stress reduction to improve animal welfare and reduce the symptom of licking.
Finally, the role of nutrition and allergies as possible triggers for licking behavior is also being investigated. Scientists are examining how certain food allergies or sensitivities lead to inflammatory conditions that increase itching in the anal area. Research in this area could lead to customized nutrition plans specifically aimed at minimizing allergens and thus reducing licking behavior.
