It’s important to see a vet to get a proper diagnosis and treatment plan.
To help you better understand the many reasons behind this troubling behavior, we’ve conducted an in-depth analysis that draws on veterinary research, behavioral science, and nutritional studies.
Our investigation is interdisciplinary, looking at both physical and mental health issues that may cause a dog to bite their bum and tail. By combining the results of these studies, we hope to offer a comprehensive perspective that not only explains the symptoms but also the causes of this behavior, so you can help your dog find relief.

The Medical Reasons Dogs Bite Their Tails
Tail biting and the biting of the surrounding area can be caused by a number of medical issues. Dr. Megan Moore of the Bergen County Veterinary Center told The Dodo that full or infected anal glands, parasites, skin infections, and allergies are some of the most common reasons for this behavior.
Dogs may bite at their tails or rear ends when they are experiencing significant discomfort from anal gland issues, hoping to find relief. Parasites like fleas and ticks can cause itching, and skin infections can cause hot spots that are painful.
The range and overlap of symptoms of these issues show why it’s so important to get a veterinary diagnosis, as the cause needs to be determined in order to treat the problem. The American College of Veterinary Surgeons explains that treatment can range from expressing anal glands to antibiotics for infections, anti-parasitic medications for infestations, and anti-inflammatories for more serious issues like perianal fistulas.
In addition, the vet may suggest dietary changes or medications to help with allergies. These issues can be painful and uncomfortable for dogs, so it’s important to get them to the vet as soon as possible to help them feel better.
Untangling the Canine Mind: Why Do Dogs Bite Their Tails?
In addition to medical reasons, psychological issues like anxiety, boredom, and Canine Compulsive Disorder (CCD) can drive dogs to engage in self-mutilating behaviors like tail biting. Dogs may engage in self-soothing behaviors like tail biting when they feel anxious due to separation or other stressors.
CCD, which is similar to obsessive-compulsive disorders in humans, is a condition that involves repetitive behaviors and can include tail chasing or biting as a way to cope. According to Phoenix Dog Training, environmental stressors and past trauma can make these behaviors worse.
The relationship between a dog and its owner is also a key factor in a dog’s mental well-being. A positive relationship with an owner can help a dog feel safe and reduce stress-related behaviors. On the other hand, a negative relationship with an owner, including neglect and inconsistent training, can lead to increased anxiety and problematic behaviors in the dog.
Behavioral modification and environmental enrichment are important for addressing these issues. The Merck Veterinary Manual recommends positive reinforcement and a consistent schedule to help dogs avoid negative behaviors and live a healthy life.
It’s important to understand these behavioral issues because dietary factors also impact a dog’s behavior and contribute to their overall health.
Exploring Nutritional Influences on Dog Tail and Bum Biting
The relationship between diet and behavior in dogs is complex, and there is some evidence to suggest that certain dietary factors can impact a dog’s physical and mental health.
For example, the Clinical Nutrition Service at Cummings School explains that amino acids derived from food, such as tryptophan, are necessary for the production of neurotransmitters that can affect behavior. These protein components may impact mood and aggression, which could play a role in stress-related behaviors like tail biting.
Meanwhile, the study Impact of Nutritional Supplementation on Canine Dermatological Disorders found that deficiencies in omega fatty acids, vitamins, and minerals can lead to skin issues, which can cause discomfort that leads to tail biting.
As a result, it’s important to make sure a dog is getting a well-balanced diet that meets all of its nutritional requirements to ensure its skin and coat are healthy and less likely to become irritated and lead to tail biting.
This includes making sure a dog’s diet includes omega-3 and omega-6 fatty acids and vitamins that support skin health and overall well-being. These nutritional interventions could be part of a comprehensive plan to help manage and potentially reduce unwanted behaviors, like tail biting due to skin irritation.
Untangling the Problem: Orthopedic Issues
Orthopedic problems, like hip dysplasia and cruciate ligament ruptures, can cause pain that leads to tail biting. The American Kennel Club explains that hip dysplasia can cause dogs to show signs of pain, like not wanting to jump or having a wobbly gait. In a similar vein, cruciate ligament ruptures can cause pain and instability in the knee joint, which can lead to tail biting as a way to cope.
Pain in dogs can be hard to spot, but symptoms like lameness, stiffness, and irritability can be signs that a dog is in pain. Orthopedic problems are usually diagnosed through a physical exam and imaging tests, like X-rays and MRIs. Dr. Jeff Grognet explains that catching lameness early is important to prevent the progression of problems like arthritis.
The treatment for orthopedic pain can range from rest to alternative treatments to surgery. The American Kennel Club lists treatments like using a strong nylon in implant surgeries or changing the joint’s conformation.
However, the sooner the problem is diagnosed, the more effective the treatment will be, and it will help the dog get back to a life free from pain and discomfort, which will also lower the chances of tail biting as a sign of pain.
Summary of Tail Biting in Dogs
In summary, dogs may bite their tails and rear ends for a number of reasons, including medical problems like anal sac issues, parasites, and allergies. Behavioral issues like anxiety and Canine Compulsive Disorder and the role of diet in a dog’s physical and mental health also contribute to the problem. Pain and discomfort caused by orthopedic issues or injuries can also lead to tail biting.
It is important to work with a veterinarian to get an accurate diagnosis and develop a treatment plan that will work. A comprehensive approach that includes medical intervention, behavior modification, and dietary changes is necessary to treat the problem in a way that addresses all of the contributing factors.
In the end, it is important to understand and treat the root causes of a dog biting its tail and rear end to ensure the well-being of our pets. Every dog is different, so a personalized approach is necessary to ensure a happy, healthy, and well-adjusted pet. And remember, the best relief comes from the combination of veterinary medicine, behavior, and nutrition.
