Dog Chewing Hair Off Tail! – Why? What to Do?

Our furry friends can sometimes exhibit puzzling behaviors that leave us scratching our heads. One such behavior is when dogs chew on their own tails. It’s a baffling sight, especially when we know they are receiving proper nourishment, exercise, and playtime. So, why do dogs engage in this repetitive and sometimes obsessive behavior? Let’s explore some of the root causes and what we can do to address it.

Emotional Issues

First and foremost, it’s important to consider emotional issues as a potential cause for tail chewing. Just like humans bite their nails when stressed, dogs may excessively bite or lick their tails as a way to cope with anxiety. If you suspect emotional issues, it’s advisable to seek the guidance of a behavioral trainer and a veterinarian. Together, they can help identify and address any underlying emotional problems that may be triggering this behavior.

Parasitic Infestations

Another possible cause of tail chewing is a parasitic infestation, such as fleas or ticks. These pesky parasites can cause irritation and discomfort, leading dogs to scratch or bite their tails in an attempt to alleviate the itching sensation. If you notice your dog continuously scratching a specific spot, it’s worth checking for fleas or ticks. Consult with a veterinarian for appropriate parasite treatment and preventive measures.


Just like humans, dogs can develop allergies. Environmental factors, such as mold and pollen, can trigger allergic reactions in some dogs. Additionally, food allergies can lead to itchiness and discomfort. If you suspect allergies, you can try eliminating potential trigger foods from your dog’s diet or consult with a veterinarian for an allergy test. It’s important to identify and address allergens to provide relief for your furry companion.

Anal Problems

Issues with the anal glands can also cause dogs to chew their tails. Signs of anal gland problems include excessive licking and chewing around the anus, scooting, and a swollen anus. If the cause is related to your dog’s diet, a veterinarian may recommend therapeutic food. In some cases, antibiotics, anal gland expression, pain medication, or surgery may be necessary to address the issue effectively.

Skin Disorders

Sebaceous glands present beneath the skin surface are responsible for keeping the skin moisturized and protected. Dogs, like humans, can experience an overproduction of sebum, leading to itchiness and a compulsion to bite and chew their tails. If you observe inflamed, red, or flaky skin and a foul odor, your dog may have seborrheic dermatitis. Consulting with a veterinarian and considering fatty acid supplements may help alleviate these symptoms.


Tail chewing can also be a response to pain in the tail region. Conditions such as arthritis, foreign bodies stuck in the skin, lower back pain, broken tails, or hip dysplasia can cause discomfort and prompt excessive grooming of the tail. If you suspect pain as the root cause, it’s crucial to observe your dog’s behavior and seek veterinary assistance to identify and address the source of pain.


Dogs with a curious and adventurous nature may sustain skin wounds on their tails during their outdoor escapades. To alleviate the pain, dogs may start to lick or bite the wound, causing further irritation. Therefore, it’s essential to thoroughly check your dog for injuries after every walk and promptly clean and treat any wounds that are found.

Attention Seeking

Some dogs may resort to tail chewing as a way to seek attention from their owners. If you notice your dog engaging in this behavior and you respond to it, whether positively or negatively, they may see it as a means to capture your attention. Socially-deprived dogs, in particular, may crave attention even if it’s negative. In such cases, a visit to the vet and a consultation with a behaviorist can help determine the best course of action.

Excessive tail chewing can lead to harmful consequences for dogs, such as the development of hot spots, which can be painful and require veterinary attention. It’s crucial to address this behavior promptly and seek professional advice when necessary to keep your dog healthy and happy. Remember, every dog is unique, and finding the right solution for your furry friend may require patience and persistence. By staying committed to their well-being, you can ensure a tail-wagging life for your beloved companion.


Why should excessive tail chewing worry dog parents?
Compulsive chewing and biting behaviors can be detrimental to your dog’s well-being. Continued tail chewing can lead to the development of hot spots, which can quickly worsen and cause significant discomfort. It’s important to protect your furry companion and seek veterinary assistance if excessive tail chewing persists.

Excessive tail chewing can have various causes, each requiring a different approach for resolution. As responsible dog parents, our aim is to find the right solutions to keep our furry friends healthy and happy. Regardless of the underlying cause, it’s essential to remain committed to the chosen course of action and work closely with professionals to ensure the best outcome for your dog. Remember, their well-being is always worth the effort!
