Dog owners often ask, why do dogs bite their tails?
Unlike the tail-chasing phenomenon which is quite harmless, tail-biting can prove to be a little dangerous for your four-legged friend. Hence as a dog owner should you see this behaviour repeatedly in your dog try to stop him by using methods best suited to both you and your dog.
Although there could be various reasons why a dog biting its tail. Some of the common ones are listed below.
1. Skin infections
This is the most common answer to why is my dog biting its tail. Skin infections can cause discomfort and itching sensation on the tails hence to relieve that discomfort a dog will chew on his tail. Take your dog to a vet for a proper examination of the tail and get the infection treated.
2. Wound/Injury
Sometimes while playing a dog might injure himself which becomes a cause of irritation and discomfort to him and to get rid of that pain the dog will either lick his tail or chew on it. This will worsen the situation, hence if you find your dog biting his tail, talk to him in a soothing voice to calm his nerves, and then try to see what the cause dog to bite his tail. If it is a wound clean it with lukewarm water and cotton and take your dog to the vet for treatment.
3. Docked tail
Tail docking is a procedure whereby groomers or vets cut the nip of the tail of purebred dogs to conform to a breed standard. However, sometimes what happens is that while tail docking some of the nerves is also cut which induces pain in that area thus causing discomfort to the dog and thus making him gnaw his tail. Talk to the vet for the best possible advice on this.
4. Fleas/ticks
Fleas or ticks are another reason why dogs chew their tails. Examine the tail and watch out for fleas and ticks and spray some anti-tick powder after thorough grooming of your dog. This will soothe his irritation and he will not chew on his tail.
5. Fractured tail
Tail fractures are very common in dogs, especially in dogs with big tails. Tail fractures happen when a tail gets stuck in a door, or someone steps on it accidentally. It is another very common reason why do dogs bite their tail. Take your dog to the vet for treatment before it becomes bad.
6. Hunting instinct
Dogs are born hunters and it is this instinct which makes them chase their tails and if and when they finally catch hold of it to chew on their tails. However, as a pet owner, you should remember that while tail chasing is not dangerous for your dog but biting his tail is. So make efforts to stop this behaviour by getting your dog to wear a collar.
7. Compulsive behaviour
Some breeds of dogs are prone to tail chasing and tail biting. The result is a vicious circle wherein a dog bites on his tail to get rid of irritation, however, biting results in more irritation, and thus increased biting. You can talk to the vet regarding it and put a collar so that he is not able to bite on his tail.
8. Previous trauma
Another reason why is my dog biting his tail could be because of some previous trauma or wound he suffered on his tail. Sometimes the wounds heal but the pain remains and it could be this pain that causes your four-legged friend to chew on his tail. If you have just bought a puppy inquire about any trauma or wound that the dog has suffered so that you are better equipped to deal with his tail-chewing phenomenon.
In all these above-mentioned reasons the common thing is irritation in the tail. So if your dog is biting on his tail remember that there is some irritation or pain that your dog is trying to get relieved of. So now that you know it is the irritation that causes your dog to bite his tail the next step should be to identify the cause of that irritation.
Why Dogs Bite Their Tails: Behavioral Reasons to Watch Out For
Sometimes, it’s not just a quick itch or a flea that’s got your dog going at their tail. Here are a few behavior-related reasons that might be behind all that tail-chewing:
- Boredom – Just Plain Old Boredom!
Ever feel restless with nothing to do? Dogs do too! When dogs don’t have enough to keep them busy, especially high-energy types like Border Collies or Jack Russells, they start looking for something to fill their time – and sometimes, that “something” is their own tail. It’s like when we twiddle our thumbs or bounce our legs! Giving your dog more playtime, daily walks, or a fun puzzle toy could be just what they need to stop the tail-chewing. - Stress and Anxiety – They Feel It Too
Dogs pick up on stress just like we do. Changes in their routine, loud noises, or separation anxiety (yep, dogs can miss us a ton!) might lead them to chew their tails as a way to self-soothe. Maybe your pup is stressed from moving houses, a new pet, or just the usual hustle and bustle of home life. Look for other signs, like whining, pacing, or chewing up things they shouldn’t. A vet or pet behaviorist can help with training or calming aids to ease their nerves. - Compulsive Behavior – When It’s Hard to Stop
Sometimes, tail-biting isn’t just a habit; it can turn into something like an obsession. For dogs, this behavior might even be linked to their breed, especially the smarter, high-energy ones. If your pup can’t seem to stop, it could be a sign they need extra help to manage this compulsive behavior. A vet can work with you on this, maybe with a mix of training, environment tweaks, or even meds in certain cases.
When to Call the Vet?
Not sure if it’s time to get some help? Here’s a quick list for when a vet visit might be a good idea:
- If your dog’s tail-biting is getting out of hand or happening all the time.
- You spot any redness, swelling, or smell something funky (infection alert!).
- They’re hurting themselves or losing fur from dog chewing on tail so much.
- You’ve tried keeping them busy or easing their anxiety, and it’s still happening.
AVMA might say something like:
“Tail biting is often linked to underlying medical issues such as allergies, infections, or external parasites. If left unchecked, it can lead to chronic problems.”

How to Prevent Dog Chewing on Tail: Practical Tips and Solutions
If you’re tired of seeing your dog bite at its tail, there are several steps you can take to prevent the behavior and keep your pup happy and healthy. Here’s a breakdown of what you can do:
- Provide Enough Exercise and Mental Stimulation
Just like us, dogs get restless when they’re bored. A tired dog is a happy dog (and a dog that’s less likely to chew its tail)! Make sure your dog gets enough exercise—daily walks, runs, or even doggie playdates can help burn off energy. Puzzle toys or treat-dispensing toys can also keep their brain engaged. - Use Chew Deterrent Sprays
Sometimes, a little bit of help from a product can make all the difference. You can try using a chew deterrent spray, which tastes bitter or unpleasant to dogs. A few sprays on their tail can make the habit less tempting. Brands like Vet’s Best Bitter Cherry Spray or Grannick’s Bitter Apple are popular choices. - Introduce a Cone Collar (Elizabethan Collar)
If your dog can’t seem to stop biting their tail, a cone collar might be necessary to prevent further damage and allow healing. It might look funny, but it’s effective! This temporary measure ensures that your dog won’t be able to reach their tail to chew it. - Address Underlying Health Issues
If your dog is biting their tail because of a skin issue, allergy, or infection, treat the root cause. Regular vet visits and the right treatments, like flea control or anti-itch sprays, can help prevent tail-chewing behavior triggered by these conditions. Don’t hesitate to ask your vet for specific products tailored to your dog’s needs. - Behavioral Training
For dogs with anxiety or compulsive behaviors, behavioral training can help. You can work with a professional trainer to teach your dog better ways to cope with stress, anxiety, or boredom. Positive reinforcement can also be helpful—reward your dog for staying calm and not chewing on their tail. Training might take time, but with patience, it can make a big difference. - Keep Them Busy and Distracted
Sometimes, all your dog needs is a distraction. Chew toys, bones, or interactive toys can keep them occupied and prevent them from turning to their tail. You can even try long-lasting chew treats like Bully Sticks or Kongs filled with peanut butter (just make sure the treats are safe for your dog’s size and breed!).
