Common Causes & Treatment for Tail Biting and Chewing

Below are just some of the reasons that dogs start biting or chewing their tails.

External Parasites

Fleas, ticks, and worms can drive a dog crazy. A dog will chew their tail excessively in reaction to a parasitic infestation. This becomes an issue when your dog spends a lot of time outdoors, especially, during the spring and summer months.

Some dogs and cats are allergic to flea saliva, which causes them to itch uncontrollably.

If your dog has ever had fleas before, you know they will bite, lick, and scratch at the spot in an attempt to get rid of the discomfort. Relief won’t come until you use preventative measures such as a flea bath, or over the counter flea medications.

Internal Parasites

Both tapeworms and roundworms can be the cause of making your dog’s hind itch. The itching can cause your pooch to lick, scratch, rub, and scoot to relieve the itch. Dogs become infected when they ingest a flea that is carrying the immature tapeworm larvae, hunting, and grooming.

Nursing mothers can pass roundworms and hookworms to her pups. Roundworms can be transmitted to humans when they come into contact with contaminated stool or soil.

If your pooch has become infected with internal parasites, they will need to go to a veterinarian, which will administer a medication.

Like people, dogs can develop compulsive behaviors if they are stressed or anxious. Stressed dogs are known to fly bite, chase, bark, suck or bite on different parts of their body, spin, tail chasing, and etc.

Impacted Anal Glands

It could also be that your dog is biting at the base of her tail until it is bleeding because of an impacted anal gland. Your Pugs anal glands play an important role in your pup’s life. They are the way that dogs greet and learn about each other.

This is one of the reasons that dog’s sniff each other’s rear ends when they first meet. Their anal glands give off unique smells that helps dogs learn about each other. It sounds disgusting, but it’s similar to how we shake hands when we meet someone new.

It’s not unusual to see dogs scooting, biting, and licking their rear end if their anal glands are bothering them. Your dog won’t stop biting or scooting until you secrete the anal glands. A high fiber diet may also help make your dogs stool harder, which will help their anal glands secrete better.

Stress and Anxiety

All dogs are vulnerable to separation anxiety, even Pugs. Pugs are companion dogs and love being around their human family. When left alone for long periods of time, your pup might start showing signs of obstructive behavior. This could lead to chewing their tail, scratching walls and etc.

Hot Spots

A hot spot ( aka pyotramatic or moist dermatitis) is a condition when your dog’s skin develops infected lesions or open wounds from scratching and licking so much. These spots can appear anywhere on the body, even the tail.

Hot spots require moisture and bacteria to form. Untreated hot spots can quickly become large red, irritated lesions.

Poor Hygiene

Without proper hygiene, your dog’s anal area can become itchy. The hair around their anal area can have fecal matter, or they can even have poop on their behind from where they just went bathroom.

Dogs in general are pretty clean and are constantly grooming themselves. However, it is hard for them to reach all the way around and clean their behinds.

If this is what’s causing your pup to chew her tail until she draws blood, just give her a bath using a good dog shampoo and this should take care of the issue.
