Dog Biting Base of Tail, but No Fleas: Causes and Remedies

My dog keeps biting their tail, but no fleas?

If your dog keeps biting its tail and you have confirmed that there are no fleas, it might be because of allergies, anal gland issues, or an injury. It can also be that your dog is bored or anxious.

In this article, we explain 8 potential reasons for your dog biting its tail, how to identify the problem, and home remedies to try.

Why is my dog chewing their tail?

The most common reason for your dog chewing its tail is because a parasite like fleas, mites, or ticks have latched on and caused irritation. Other times, it might be that your dog’s anal glands are infected or blocked, your dog is allergic to something in its environment, or it has injured its tail.

Allergies

Dogs can develop allergies like humans. If your dog is allergic to something in its environment, like plant pollen, dust mites, certain foods, or even cleaning products, it can lead to itchy skin.

If you notice this happening frequently, you should see a vet to help you determine what is causing the allergic reaction and suggest changes to your dog’s diet or environment.

Other parasites besides fleas

Mites (a common cause of mange) and ticks can latch on, cause localized irritation, and make your dog’s tail incredibly itchy. Additionally, if your dog has lice, it can lead to intense itching. 

These pests are sometimes harder to spot than fleas, so a thorough check by a vet might be necessary to identify and treat them.

Infections and wounds

If your dog has injured its tail or the surrounding area, it might chew on it to try to soothe the pain. However, this can worsen things, leading to more irritation and even open sores.

Sometimes, the pain might be from a deeper issue like arthritis or a spinal problem that causes referred pain in the tail area. 

Anal gland issue

Your dog’s anal glands are small sacs near their anus that release a smelly secretion during bowel movements. These glands also help dogs mark their territory and get to know other dogs by leaving a unique scent. This is why you see dogs sniffing each other's rear ends when they meet.

Sometimes, the glands get blocked or infected, making your dog uncomfortable. Chewing on the tail may relieve some of that discomfort. You might also notice your dog scooting its rear end along the ground or licking the area more than usual. 

You should see the vet if you suspect an issue with your dog’s anal gland.

Behavioral issues

Sometimes, dogs chew their tails out of boredom, anxiety, or stress, especially if they lack mental or physical stimulation. This behavior is also common in dogs dealing with separation or sudden changes in the home. 

In this case, try providing more mental stimulation with things like squeaky toys, or increase your dog’s exercise. If these simple remedies don’t work, you might need to consult with a vet or a professional trainer.

Hormonal imbalances

Hormonal issues like hypothyroidism or Cushing’s disease can cause changes in your dog’s skin, leading to dryness, thinning hair, and increased risk of infections. These conditions can make your dog itchy and lead to tail chewing. 

Your vet can diagnose these issues with blood tests and prescribe treatments to manage the condition.

Perianal fistula

Perianal fistula, also known as anal furunculosis, is a painful and serious condition where infected tunnels form around the anus. These tunnels cause severe discomfort and itching, leading your dog to chew or lick at the area to relieve the pain. 

If your dog has perianal fistula, you might also notice other symptoms like difficulty defecating, blood or pus around the anus, or a foul odor. This condition requires urgent veterinary attention to manage and relieve your dog’s pain.

A foreign object stuck on the tail

Sometimes, dogs chew their tails because they have something stuck on or wrapped around them, like a splinter or even a piece of fabric or string. 

If you notice your dog suddenly starting to chew its tail, it’s a good idea to check for any objects that might be caught. Carefully remove anything you find, and monitor the area for signs of continued discomfort or infection. 

If the object caused a wound or you can’t safely remove it, it’s best to see your vet for help.

Home remedies for dog biting its tail

Dog tail covers

Dog tail covers act as a protective shield for your dog’s tail. If your dog has sores, wounds, or hot spots from excessive biting, a cover can help protect these areas from further trauma. 

However, you should also address the underlying cause of the tail biting. For example, if your dog is biting due to allergies, skin infections, or anxiety, treat those conditions while using the tail cover as a supportive measure.

Cones

Putting a dog cone (also known as an Elizabethan collar or e-collar) around your dog’s neck can prevent your dog from licking or biting at its tail, wounds, or stitches. These collars extend outward from the neck and form a barrier that stops the dog from reaching most parts of its body with its mouth, like the tail.

Apple cider vinegar

Apple cider’s antibacterial and antifungal properties can help with any parasite and itching that might be causing your dog to bite its tail. Plus, the bitter taste of apple cider can discourage your dog from biting its tail.

Mix equal parts of apple cider vinegar and water in a spray bottle. Then, spray the solution on your dog’s tail. However, be careful to avoid open wounds, as this can sting.

Aloe vera gel

Aloe vera is especially effective if your dog’s tail biting is due to minor skin irritations or hot spots. Apply a small amount of pure aloe vera gel directly to the affected area.

Chamomile tea rinse

Chamomile has anti-inflammatory and soothing properties that can calm irritated skin. Brew a cup of chamomile tea and let it cool completely. Then, pour it over your dog’s tail.

Distract with a chew toy

A chew toy (especially one that squeaks) can redirect your dog’s attention away from their tail and keep them busy. 

Regular grooming

Grooming plays a key role in managing dog tail biting. Keeping your dog’s coat clean and free of tangles or debris reduces skin irritation and discomfort. Likewise, brushing your dog’s fur helps to distribute natural oils throughout their coat and reduces dryness.

Allergen management

If allergies contribute to your dog’s tail biting, identify and eliminate them from your dog’s environment. This might include switching to hypoallergenic dog food or reducing exposure to pollen and dust. 

Additionally, regularly clean your dog’s bedding and use air purifiers to minimize allergen levels.

Calming pheromone diffusers

Calming pheromone diffusers reduces stress and anxiety, which may be contributing to your dog’s tail biting. These diffusers release synthetic pheromones that mimic the calming signals dogs naturally produce and are useful for stressed or anxious dogs due to changes in their routine or separation.

Treatment for dogs chewing tails raw

If your dog has been chewing its tail raw for more than 24 hours and you have tried different home remedies, see a veterinarian as soon as possible. Open wounds can easily become infected. In the meantime, use a cone or e-collar to prevent further chewing.

Tail biting in dogs: summary

If your dog bites the base of its tail without any signs of fleas, it could either be bored or in need of grooming.

If you notice additional symptoms, such as intense pain, redness, swelling, bad odor, discharge, prolonged chewing, or hair loss, you should schedule a visit to the vet immediately.

Meanwhile, have an e-collar or tail cover on hand to protect the area from your dog.
