Until the cause of grass sickness is known it is difficult to give sound advice regarding prevention. This section provides an introduction to the disease, management strategies for nursing chronic grass sickness patients, risk factors and other related articles.


Acute and subacute cases will die eventually unless euthanized but some chronic cases are treatable and eventually return to a useful working life. Many years of experience gained by veterinarians and nurses involved in the diagnosis and treatment of large numbers of grass sickness cases at the Royal (Dick) School of Veterinary Studies, near Edinburgh has resulted in many more horses being able to be nursed at home by their owners.

Until a vaccine is trialled and proven to prevent grass sickness owners have no choice but to implement management practices which may reduce the risk of the disease occurring.
