Tail tip necrosis dog breed disease

Hedgehog Syndrome is also called Tail Tip Necrosis (TTN) or Tail Dyeing Syndrome. The Hedgehog Puppy Registry provides extensive and up-to-date information about TTN and many other hereditary, congenital or acquired diseases of dogs.

This inherited disorder is a progressive hereditary problem, that the affected puppies are born with a condition where there are spots present on the tail, which are very painful and hard.

This problem affects only the puppies and not the adults. The cause is unknown. It has also been linked with poor nutrition, infection and parasites, exposure to toxic chemicals, hormonal disorders, genetics and immune system.

It is always genetic in nature and the disease can affect the whole body in the later stages. It is caused by an enzyme disorder in the dog, due to which the enzyme called keratan sulphate is not produced in adequate amounts.

This enzyme is necessary for the skin to make a natural protection in the body. This enzyme is secreted from the liver and therefore the disease can be prevented through the normal healthy nutrition and the healthy diet.

Hedgehog syndrome is characterised by tail spots that vary in size, position and shape in a random manner, as also by other different symptoms, such as hair loss, excessive shedding, itching, skin ulceration, skin inflammation, vomiting, weight loss, neurological disorders, skin infection and loss of strength.

This condition usually appears between the ages of two to seven weeks and can last up to seven to eight years. The disease is hereditary and can cause various disorders such as:

Hair Loss

Scaly Skin

Joint Disorders

Itchy Skin


Muscle Weakness


Tail Tipping




Crusts in the mouth

The condition is commonly seen in breeds like Great Dane, Rottweiler, Yorkshire Terrier, Chihuahua, Dachshund, Pekingese, Shih Tzu and Boxer.

So, what do we mean by hedgehog syndrome?

This is a disease of dogs. It is characterised by hedgehog like skin patterns, which appear on the skin of the dog. It is due to the lack of keratan sulphate and they are also known as hedgehog dermatosis.

This is one of the most common skin disorders of canines. A healthy dog’s skin is made up of various cells and other materials. Some of the cells are dead and this is why when they are exposed to sunlight, certain things can happen. When you have a dog and this is in a small area, it affects them so it can lead to skin ulceration, hair loss and skin irritation.

The syndrome is also characterised by the presence of an abnormal amount of protein or mucopolysaccharides in the hair. The protein gives the appearance of the ‘hairy’ part of a hedgehog while the presence of mucopolysaccharides gives the appearance of the hedgehog’s skin.

Causes of hedgehog syndrome

There are several factors which can cause the development of hedgehog syndrome in dogs. Some of these are:


Genetic mutations

Nutritional deficiencies


It is important to note that these can only be one of the reasons, which cause the development of the syndrome. It is very possible that a combination of all the mentioned factors is responsible for this condition.

Symptoms of hedgehog syndrome

So, what does this disorder cause to the dogs?

The condition of hedgehog syndrome is characterised by the development of skin ulcerations on the ears, tail and other areas.

In dogs, the symptoms are the most severe when they have skin ulcers and inflammation. The most common area affected in dogs is the ear, which is due to their constant exposure to the elements.

There is also development of bald patches in certain dogs, which is associated with the hair loss. In addition, there is increased shedding of the dog’s hair.

Furthermore, the skin of the affected dog is irritated due to the presence of excess protein, which gives the appearance of spiky hair on them.

In some dogs, the hair loss and skin irritation are more severe than others. Some affected dogs lose up to an 80% of their hair within a period of time.

The mucopolysaccharides in the skin and coat of the affected dogs are responsible for the spiky hair and excessive shedding. These in turn, makes the coat look unkempt and unsightly.

As the hedgehog has no natural predators, this disease can be transmitted through direct or indirect contact. Even though hedgehog syndrome is more common in dogs than other species, the same condition is also seen in other animals such as cats, cats, horses, cattle and rabbits.

Hedgehog syndrome in dogs is a condition that is usually treated with pain medication and topical steroids. Some dogs require treatment with antibiotics and anti-inflammatory agents.

It is important to control the symptoms of hedgehog syndrome as soon as possible to minimise the pain and discomfort experienced by the dog. Once the disease progresses and affects the lungs, then it is necessary to seek professional veterinary assistance.

Prevention of hedgehog syndrome

It is important to understand that the hedgehog syndrome can be prevented and is also easily treated. It is recommended that the risk factors for developing the disease are reduced in the dog.

Since the condition is more common in the summer and autumn months, it is recommended that the dog’s caretaker provides him with plenty of fresh, clean bedding, so that he has the right microclimate to reduce the risk of developing this disease.

Make sure that your dog’s bedding is not soiled, as this could trigger an outbreak of the disease in your dog.

Also, it is necessary to keep the dog’s coat short in the summer and autumn months.

When caring for your dog, make sure that he is not over hydrated as this will make him more susceptible to the disease.

It is also recommended to trim the dog’s hair from his armpits and his tail as the hedgehog can infect the skin through scratching.

Hedgehog has a strong negative connotation to it and it can even cause dogs to associate their owners with disease. However, as there are a number of dogs that have been diagnosed with the disease, the condition is not all that dangerous for the dog.

Precautions to be taken when treating your dog are:

Always take care when treating your dog and follow the guidelines provided by your vet.

Use the right medication for your dog.

It is advisable to use a natural remedy in the event that your dog is suffering from an overdose or overdose of the medication.

If your dog has a very aggressive nature, do not attempt to treat the skin area that the hedgehog has infected.

You can keep the wound or area you have treated in a plastic bag and cover it with a bandage to prevent the hedgehog from entering the area.

You can also apply a paste made from eucalyptus and white oak.
