Your dog is doing this because he is itchy and feeling discomfort on his tail. There are a number of reasons why this could be happening. Fleas are the number one cause for itching and for a dog to chew the hair off his tail. Other usual causes of a skin irritation are allergies, mites and ticks.
Fleas: In one day, one flea can bite your dog almost 400 times. One female flea lays hundreds of her eggs onto a dog. A dog might become over sensitive to the saliva of fleas and will develop dermatitis due to a flea allergy. This can cause anaemia in your dog if left untreated.
Allergies: A dog allergy will either be a food allergy, an environmental allergy or a contact allergy. A food allergy occurs when a dog is sensitive to a certain ingredient in their food. An environmental allergy usually involves a dog inhaling certain allergens. A contact allergy involves any allergen touching a dog's skin. When a human gets an allergy they get a runny nose. When a dog gets an allergy they get an itchy skin.
Mites and ticks: A tick infestation occurs more rarely than a flea infestation, but the consequences are more serious. They can give a dog Lyme Disease or Tick Bite Fever. They have to have an injection at the vet otherwise it may prove fatal. Ear mites and mange mites cause irritation and intense itching to a dog. This must also be treated promptly to prevent a serious health problem.
Other causes: There could be an underlying condition for a dog's itching, for example cancer. Damage to the nerve endings that are caused from disease or injury can also cause extreme skin discomfort. A dog that has experienced any psychological trauma through confinement or abuse will probably pull out its hair compulsively. Any case of hair pulling or skin chewing must be taken to the vet. There are effective treatments for a dog's flea control.
