Description

A PREPARATION

FIELD OF INVENTION

The present invention relates to a preparation or composition for treating itchy skin. Reference will be made in the specification to the use of the invention with respect to animals. The present invention has particular but not exclusive application for use with dogs. The patent specification describes this use but it is by way of example only and the invention is not limited to this use.

BACKGROUND OF THE INVENTION

Itching can be very common in pets, especially dogs. Itching is one of the most common reasons dogs are taken to vets, with about 1 in 10 dogs suffering from itching.

Scratching of the skin can intensify itching and even cause further damage to the skin. Persistent scratching can lead to secondary skin infections and lesions. Itching can also lead to depression in animals.

There are a number of reasons why pets and dogs in particular may suffer from itchy skin, these can include insect bites, fleas, infections, food intolerances and allergies.

There are a number of ways that itching can be treated. These include the use of antihistamines, Corticosteroids, local anaesthetics and the application or ingestion of omega oils amongst others.

A problem with some of these treatments is that they can be harsh and have dangerous toxic side effects particularly with prolonged use. Steroids, both topically applied and orally ingested steroids can soften bones and affect the heart in dogs.

The application or ingestion of omega oils may be able to help prevent itching, but may not be sufficient to treat an existing itch.
