Sheep have been man's friend for thousands of years, especially for their multiple uses. Once raised for its meat, wool and skin for food and clothing, the sheep is now a useful companion for the maintenance of public green spaces and private gardens. These peaceful animals are now invited into our homes for their qualities, especially in terms of ecology and maintenance of vegetated areas. On the other hand, the needs of the sheep are often misunderstood or simply underestimated. Social and gregarious, this animal cannot live alone.
